I might build a scale version of it actually

#

And run it at Train Mountain

#

Hauling a comically long train

tender root
#

huh neat

solid elbow
#

It’d be quite the thing

gusty kestrel
solid elbow
#

No

#

It has no destination

gusty kestrel
#

.... And the crew set off, doomed to ride the rails for the rest of eternity, never to stop, for their destination never existed

solid elbow
#

I just did some quick math, and if I build this at 1/8 scale it would be 20ish meters long including the tenders

gusty kestrel
#

Oml

#

Long boi

solid elbow
#

12ish meters for the loco itself

#

The rest is tenders

gusty kestrel
#

....how long would that be IRL?

solid elbow
#

160 meters

#

ish

#

"...and when they came back, the locomotive was missing, and the crew was never heard from again! Hahahah!"
"Anyways, that's how I lost my engineer's license."

Pffff

over 3000 posts in this thread 🥳

shadow raft
#

Gee

ornate spindle
#

I’m happy I made this thread.

#

Even if nobody knows who I am.

tender root
#

I like that the 3000th message is "ish" haha

solid elbow
#

3000ish messages

tender root
#

oh no wait I counted wrong

solid elbow
#

The scale 4-10-10-10-10-10-10-10-10-10-10-4 would be almost as long as the Big Boy

#

Without counting its tender

#

But counting the decuplex’s tenders

gusty kestrel
#

Oh....oh

#

Wall of locomotive

solid elbow
#

The approximative tractive effort of the real size decuplex is 3MN

#

3,000,000 N

#

Many much powa

#

Many much fun

gusty kestrel
#

Haul anything, maybe somewhere.

solid elbow
#

Could someone calculate the scale version’s tractive effort?

#

I estimate its power at about 5 times that of the Big Boy

shell briar
#

idk what you using but cant you grab the smoke box nodes? (like in blender basically)

tender root
shell briar
#

i see the problem

shadow raft
#

Just one long cylinder, not 2 cylinders 😔

tender root
#

yeah

#

that's a way better way of explaining it haha

shell briar
#

o well
keep up the good work🫡

broken lion
#

Question, what would be the highest power configuration for the ingame 282 that could be created (that isn’t necessarily in the mod) 🤔

#

2-18-2 supremacy

shadow raft
#

Where was that graph...

#

So, in theory, the more wheels you add, the more TE you have.

#

0-∞-0 would be your best bet.

broken lion
#

xD

#

Nice

shadow raft
#

In terms of best adhesion, it seems 0-10-0 and 0-8-0 are the best.

broken lion
#

Why is the 2-8-0 and fast 2-8-2 so much worse 🤔

shadow raft
#

Bigger wheels.

broken lion
#

Ohhh

shadow raft
#

Well to be fair about the wheel count.

#

They get smaller and smaller.

#

So that's the actual thing behind the TE.

broken lion
#

So you want adhesion to prevent wheel slip right?

#

Or is that smth else

shadow raft
#

Yeah.

#

Satiric can tell you better, but if I'm not mistaken, as you get smaller wheels and get more TE out of them, it's easier to slip thanks to the increased power that gets transmitted?

#

Because the axle load gets smaller and smaller.

broken lion
#

Ah Kk thanks

#

I am the average steam enjoyer and wish to haul exceedingly heavy things out of places they probably shouldn’t be hauled out of 😎

#

ignore the massive amount of times things stall

solid elbow
#

Indeed. That also means a 0-4-0 with wheels the size of those on the 0-12-0 would slip the least

shell briar
#

I wonder if its possible for the locos to keep there wheel arrangements after loading back in
Coz when i start my RSO play trough i would like to have a set loco with specific drivers for there respective jobs

solid elbow
#

You can adjust it with the comms radio

ornate spindle
#

But he said it would never be possible.

#

Well, not never.

#

It was something about the save state.

shell briar
#

🤔(probably already in the thred but ima go at it anyway)
Theres this mod that saves the loco stats like windows and doors i wonder if that would be compat with this then

solid elbow
#

Such a mod exists?

shell briar
solid elbow
#

It might be a mod to fix te issue of the doors closing when leaving the locos

#

Which is now obsolete because of Sim

shell briar
#

🤔nuts

#

Have you considered keeping the vanilla trailing wheel for X-X-2 configurations?

solid elbow
#

if I’m not mistaken you can set that up in the mod settings

tender root
#

Yeah you can

ornate spindle
#

I was thinking about making a video with it.

tender root

#

in the mod config screen (which opens at the start of the game by default) you can click on the slider icon on the line where rearranged S282 is.

ornate spindle
#

I can’t wait for the next update

gusty kestrel
#

Neither can I, I'm also enjoying watching this mod evolve.

humble frost
#

same, also gives me accurate enough polar express so 8 year old me would be super proud

#

but can't wait till duplexes

rich steeple
#

Now we just need a 6-4-4-6 and a prr S1 body kit

humble frost
#

the s282 tweaks mod gives it an s1 styled boiler

ornate spindle
#

@tender root is there a setting to change the topspeed of a wheel configuration?

tender root
#

no, you change top speed by changing wheel diameter

ornate spindle
#

I wanna make the SH282 reach 145

#

Mainly just mod it to reach 145

tender root
#

Hyce has made the stock S282 do 152

ornate spindle
#

Really?

#

Huh.

tender root
#

Yeah on that long straight through the steel mill I believe

ornate spindle
#

I keep winding it up to 90 and then I usually have to slow down,

tender root
#

Wait maybe that was with the 4-4-0

ornate spindle
#

I wanna reach it in a Berkshire,

tender root
#

you and your berkshire haha

#

I've never seen someone so obsessed over a single wheel arrangement

ornate spindle
#

The perfect one if anything,

#

8 large drivers, perfect for both speed and power,

#

And four trailing wheels to support the massive firebox,

#

And two pilots just to balence it out

tender root
#

Clearly 2-10-2+2-6-2 is the best

ornate spindle
ornate spindle
#

Roughly around 142kph

ornate spindle
#

what is the max tonnage for the high speed 2-8-2

tender root
ornate spindle
tender root
#

huh, interesting. But you can get up it in the regular S282 with 1100t?

ornate spindle
#

I had 13 bars

#

Full cutoff

#

And I just stalled.

tender root
#

Weird, IDK what's going on there

ornate spindle
tender root
#

Shouldn't make a difference

ornate spindle
#

I was already kinda going slow,

#

But the cutoff was full, it shouldn’t have mattered.

tender root
#

Yeah I'll have to look into that. There could definitely be a mistake in my calculations somewhere

ornate spindle
#

I even turned off wheel slip and wheelslide

#

I should have had the full power of the Fast 2-8-2

#

I mean, you could just slightly tweak the power of the piston stroke

tender root
#

Well I'd rather figure out why my calcs don't match the game's calcs first

ornate spindle
#

Alright,

#

I’d be happy to help run some tests,

tender root
#

Yeah would be nice to see if any of those tonnage ratings are vaguely accurate

ornate spindle
#

Same 690,000

tender root
#

So the atlantic made it, but the high speed 2-8-2 didn't?

ornate spindle
#

What-

#

Heavens no!

#

That stalled almost immediately.

tender root
#

ok I see. Was gonna say, that'd be real strange

ornate spindle
#

I did however make it up the grade when I swapped it to the 2-8-4

#

Incase it mattered I was pulling 20 empty coaches and 3 aux tenders

#

Which added up to 690,000kg

#

Which should still somewhat be within the limits

ornate spindle
#

Might have been a fluke

tender root
#

yeah if you could that would be nice

ornate spindle
#

Alright, I'll use the high speed 2-8-2

#

same grade,

#

Say, what is the steepest grade there?

#

from OWN to IME

tender root
gusty kestrel
#

the first quarter of the spiral it seems, with the 2.3-2.4% grade there, then it looks to level, then jumps to a 2%, and then drops to a 1.0-1.5 percent grade from there

ornate spindle
#

I stalled on the 2.9 grade

#

Around here,

#

Which is weird, because I made it up the 2.8 grade just fine

gusty kestrel
#

the 2.8 looks to be half that length though

ornate spindle
#

Was it just simply to much?

gusty kestrel
ornate spindle
#

I was only pulling 690t

#

Which should have been within the range

ornate spindle
gusty kestrel
#

then I guess that particular stretch out of MB isnt much of an option to use closer to tonnage? unless there is an equation for %max tonnage limit reduction per % of grade?

tender root
#

traction is scaled by 1 - 5 * grade / 90

#

where grade is an angle between 0 and 180 degrees

ornate spindle
#

And what’s the conversion for tonage?

tender root
#

There's no easy equation for tonnage, it can really only be found through experimentation

#

which actually says 1130 tons going out of the harbor

#

Which is a short stretch of 2.4% followed by a longer stretch of 1.5%

gusty kestrel
#

hmmm.

#

Imma try something

ornate spindle
gusty kestrel
#

ok.... wait

#

reckon it could be not so much a question of tonnage here, but a question of momentum?

ornate spindle
#

Slowly making my way up,

#

I’m gonna try and see if I can get her up to 60 before it’s too late

#

Too late,

#

JUST ABOUT MADE IT TO MB

#

Almost didn’t make it.

tender root
#

nice, congrats

ornate spindle
#

…I think I’m about to stall again.

#

In the exact same spot

#

And I have.

#

Right here.

#

So close

#

So I make it past the 2.9 grade

#

But not the 1.8????

gusty kestrel
#

so, I started with a runup out of harbor with 16 cars worth of steel rolls plus an aux tender, and got this far with the high-speed mikado

#

so roughly about 1,014 tons is too much for the high-speed, imma knock off a couple of cars. each is worth about 63 tons

ornate spindle
#

Yeah, I only went for 690 tons

gusty kestrel
#

imma knock it down two cars and try again

#

that should put me under the estimated tonnage

#

it made it after knocking off a couple of cars

#

the lowest speed it got to was about 17 or 18 kph, it hovered at about 20 when it got to the 1.5 grade and stayed there.

#

staying at about 12 bar

ornate spindle
#

That wasn’t the grade I was at though,

gusty kestrel
#

I know, I figured i would do the harbor test

#

so the tonnage I did out of harbor was 888, if my math is correct

#

could abosolutely pull more, though it would be a slog

tender root
#

Modelling is 99% done. Been working on the simulation side of things for the past few days. The front and rear engines are now simulated separately and will wheelslip separately

tender root
# swift island What's the 1%?

The main rods need to be shorter. RIght now I'm just scaling them in one axis but that makes them look squished so I've got to edit their mesh to make a shorter copy of the existing main rod mesh

#

In terms of simulation, I have to get the rear cylinder cock particle effects working, the rear wheelslip sparks working, and I need to scale up the weight of the duplexes so that they don't wheelslip quite as bad as they do now

plush kraken
#

like 2-6-6-2

broken lion
#

would the duplex be more powerful? (im not good at train lore)

silver prairie
#

Has long it can also grip the rail

broken lion
#

nice

silver prairie
#

but.. also uses more steam

#

Also is the new Caprotti valve gear going to change performance of the loco and how?

shadow raft
#

Duplex gaming

tender root
gusty kestrel
#

How much more steam does the duplex use?

tender root
silver prairie
#

And were going to need it because its going to use more steam

tender root
#

It's still not that much more efficient though. It'll have about 1.5 times the power as the regular S282, but also about 1.5 times the steam usage.

gusty kestrel
#

this is gonna be fun to use

tender root
#

Actually technically it'll be more efficient with the reverser all the way forward or all the way backwards, since it only goes up to 80% cutoff instead of the stock 90%. Still uses crap loads of water though

tender root
#

Yeah I forget exactly what my spreadsheet says

silver prairie
#

Will we be able to change the valve gear?

tender root
#

Nah it'll only be on the 2-4-4-2 and 4-4-4-4

#

If there's a lot of demand for that though I could do it in a future update

silver prairie
#

so the x-4-4-x only uses the Franklin B2 valve gear?

tender root
#

Yeah. The original inspiration for doing this, was that making the x-4-4-x would have required significant animation changes to work with walschaerts, and I suck at animation. And the animation for rotary valve gear is braindead simple

silver prairie
#

k

tender root
#

I still suck at modelling parts in Blender, so I modeled everything in Autodesk Inventor instead

silver prairie
#

Now I'm wondering if can out pull a DE6

#

In tractive effort

tender root
#

It should yeah

broken lion
#

Steam only runs out the harbour just got interesting XD

tender root
#

Yeah that picture was from a run pulling 1500t out of the harbor

silver prairie
#

The west side?

tender root
#

Yeah

broken lion
#

:D

tender root
#

And that definitely didn't feel like the limit, although there are still simulation changes to be made so we'll see

tender root
#

The limit is the job spawning - you can't really take 1500t to one location haha

broken lion
#

I wonder if it’s possible to hook every job on the map to a few locomotives and then couple it to the front and then pull it in a giant circle

silver prairie
#

So a duplex is 1.5 more powerful then the tonnage of a stock 282

tender root
#

Still haven't finalized the tractive effort, but it will probably be about there

silver prairie
#

which is 1400 tons

ornate spindle
#

How much can the DE6 pull?

silver prairie
#

but you took like 1500 tons

silver prairie
ornate spindle
#

Huh.

broken lion
ornate spindle
#

@tender root Will you make a 2-8-2 and a 2-8-4 booster

tender root
#

like a tender booster?

ornate spindle
#

No trailing

#

A locomotive booster for steam locomotives is a small supplementary two-cylinder steam engine back-gear-connected to the trailing truck axle on the locomotive or one of the trucks on the tender. It was invented in 1918 by Howard L. Ingersoll, assistant to the president of the New York Central Railroad.A rocking idler gear permits the booster en...

tender root
#

I've thought about it. Would be more modelling, and I'd also have to figure out the cab controls

ornate spindle
#

I mean

#

You could cheat out by just making a second lever next to the cylinder cocks,

#

It wouldn’t change the performance other then making the steam pressure take longer to build I’d reckon

#

It uses exhausted steam

tender root
#

That's basically how they worked I think. A single lever with forward, neutral, and sometimes reverse. I just haven't needed to mess with the cab controls before.

#

I thought they used steam straight from the boiler - did they really use exhaust steam?

ornate spindle
#

I mean they could use both,

#

To make it differ from the duplex you could make it a low pressure unit using reserved steam

tender root
#

Well, if it were realistic it would take damage if used at medium to high speeds

#

That could be a neat mechanic

ornate spindle
#

Yeah,

tender root
#

Although wikipedia says they can run up to 56 kph

ornate spindle
#

Yeah,

#

I’d say it should take damage when up to 80 kph

tender root
#

might be nice to take some damage @ 40 or 50 kph too, I don't think we want people doing mainline speeds with it on

ornate spindle
#

I mean, I fully plan to,

#

Probably just turn it off when I get to mainline speeds

nova cove
#

man i cant believe how far this mod has come

ornate spindle
#

I can’t believe someone actually went through with my idea

tender root
#

it's been super fun to work on

ornate spindle
#

That has always been a relief!

nova cove
#

just wait until i start asking satiric to make different valve gears

tender root
#

It will be Walschaerts and Franklin for the forseeable future

ornate spindle
#

Best case you could ask the same person that modelled the German loco’s to make the bogies

tender root
#

I suppose. I have other stuff I want to do first though. I want to do the tank S282/tender S060, then the S060 arrangements, then make articulated engines, and all that will take a while

ornate spindle
#

Alright,

tender root
ornate spindle

Oof

#

Well I’m just waiting for the high speed 2-8-4

the only reason why I wanted this mod

silver prairie
#

When will the duplexs be released?

ornate spindle
#

I mean satiric said modeling is 99% done

#

Coding wise it seems 76%

tender root
#

modelling is 99% done, the sim is about 75% yeah. hopefully in a week or two

silver prairie
#

k

tender root
#

I mean, there is a large tolerance on these measurements, I'm just guessing

ornate spindle
tender root
#

4-4-4-4 is in currently, but with the second leading axle underneath the front cylinders. At some point I want to redo the front valvegear to make enough space to put the second leading axle behind the front cylinders

ornate spindle
tender root
#

not if I don't have to unfortunately. I've realized that my original strategy for modifying meshes (looping through all vertices, and moving them if they're in a certain range) is way too slow (it's gotta loop through all 50 thousand vertices on the S282)

ornate spindle
#

Oof,

#

Nevermind then!

tender root
#

If altfuture ever gets around to releasing their EULA, that will hopefully allow me to just package the mod with an updated mesh

shadow raft
#

Where 👏 EULA 👏 update 👏

ornate spindle
#

Just like, gone up.

#

And asked em?

tender root
#

In September, they told me they intended to release it "in the next few months". It sounds like the basics have all been figured out but there's a bunch of complex legal stuff they have to work through to release it for real

ornate spindle
#

Ah,

#

Good to know then!

can one of you's send me the mod

since i upgraded pc parts i lost all of my mods

#

congrats!!!

rich steeple
#

It would be cool if you could change the bogie appearance

#

To make it look abit better with the x-x-4 appearance

tender root
rich steeple
#

Yeeee

tender root
#

would definitely look cool, it'd be a pain to model though. If someone else wants to model it then it could be added

rich steeple
#

yeah. I've tried modeling a bogie like an canadian 4-6-4 and uh....
You can see it.in the back and it's just.
Not good-

ornate spindle
#

Not a whole loco,

rich steeple
#

Yeah but I mean the bogie I made at the back under the cabnis god awful

ornate spindle
#

Still it’s easier to put your 100 in one thing then a while loco

rich steeple
#

True.
Just need the right references and prints.

ornate spindle
#

Here give me a sec,

tender root
ornate spindle
#

Oh

#

Forgot about this

gusty kestrel
#

I am gonna sound really dumb here, but once they get the Diesel Electric Sim back up to par, what is the chances of being able to mess with the axel count of the DE6 and potentially have it be able to work as a DE4? I have no knowledge in how diesels are designed though.

tender root
#

Shouldn't be too hard, if the simulation is anything like the steam simulation. Again the tricky part is the modelling

ornate spindle
#

I’d just advise hollowing them out.

#

And only worrying about the visible outside

tender root
#

The second and third photos are of booster trucks, which look a little different then a regular two axle trailing truck

ornate spindle
#

The only thing that would have to be removed is the small boiler assembly

#

The general frame however is the main focus

#

Because this is is what a normal trailing truck looks like, but I don’t really see a difference

ornate spindle
#

If a two truck was modeled you could actually extend the firebox

rich steeple
#

The hudsons class has 2 different wheel sizes in the back truck and have abit more spacing between them

ornate spindle
rich steeple
#

Fair.

ornate spindle
#

You could make the floor of it deeper because the trailing truck isn’t connected to the firebox

#

I mean for the SH282

tender root
ornate spindle
#

But mostly the firebox

#

Let me get a side profile of the SH282

tender root
ornate spindle
#

That’ll do!

#

Thanks!

tender root
#

As you can see, there's a ton of crap there that would need to be figured out. It'd be a lot of work no matter what

ornate spindle
#

I mean you could also cheap out and not move the anything.

tender root
#

wasn't planning on it tbh

ornate spindle
#

Stuff like the dynamo.

#

If you do lengthening the boiler

#

Just leave it all in the same spot

#

But something like this

#

Where the firebox basically rubs against the trailing truck

#

Because it’s supposed to

#

I mean going back even here the only point of the trailing trucks is so the engine doesn’t tip backwards

#

It’s not actually connected

#

But for the most part, you could make the “extended” firebox purely a extension

#

Here have the new firebox model be its own separate piece (marked in red) and have it connect to the normal SH282 model (highlighted in green)

#

All the green would just be the model shifted back

#

And the red would be new/extended parts

tender root
#

Well I'd still need to mess with all those steam pipes + the whistle cord if I move the cab back

ornate spindle
tender root
#

To me the easiest place to extend the boiler is here

ornate spindle
#

True,

#

But would we have room to extend the firebox?

tender root
#

nah I think you're right, that moving the cab is the easiest way to extend the firebox

ornate spindle
#

We could even make it longer

tender root
#

If you have to move the rear coupler, that could mess with spawning

ornate spindle
#

Or just make it less weird,

ornate spindle
#

We would just have the cab overhang

tender root
#

If you move the cab back, you move the coupler

#

otherwise the cab clips into the tender

ornate spindle
#

Good point,

#

I’m pretty sure it could be easily fixed

tender root
#

I'm not haha

ornate spindle
#

…ye of little faith!

tender root
#

Could move everything but the cab up, but then you have the same problem with the front coupler

ornate spindle
#

I mean it’s like when this all started!

#

Like with the gauge mod.

#

The code exists

#

It just needs to be heavily altered

tender root
#

Well, I've never done mesh alterations this drastic. Keep in mind that all of these mesh changes still have to happen at runtime

ornate spindle
#

It should be fine.

#

Now that I think about it.

#

There was a mod a while ago called 'Cut pasengers' or something,

#

It made the coaches smaller for pax mod

#

The coaches still spawned and were still connected for their jobs.

#

while the SH282 isn't a coach,

#

I'm sure the game could adapt to the change in size,

#

for the actual making of the mesh,

#

...

#

that would have to wait for the EULA....

tender root
#

hmm yeah I could see what they did for that mod

#

game might handle it automatically

ornate spindle

Does anyone have the chart that designates the tonnage for each wheel arrangement?

I can’t wait to see it in the game!

But uh,

I just wanted a Berkshire and Pacific wheel arrangement.

hybrid silo
# ornate spindle But uh,

A pacific with large drivers for speed…. Will go well with the future planned straightening of some sections of track 🙂

ornate spindle
#

I’m more of a Berkshire guy,

#

With larger drivers

hybrid silo
#

Berkshires from any particular country?

ornate spindle
#

USA,

hybrid silo
#

The Japanese and Austrians had some interesting Berkshire designs. We even had a tank engine here in Western Australia of the 2-8-4 Berkshire configuration. The “K” class. Nowhere near as impressive as what the Americans had and still have.

ornate spindle
#

How is the mod going Satirtic?

tender root
#

it's going good, main thing I'm trying to figure out right now is why the rear driving wheels aren't clocked right. Which is the only major thing keeping the duplexes from release

rich steeple
#

Damn wheels-
We need you wheelin and dealin

#

We need a 4501, 611 and T1 triple header since we can't do the 1307 we can take the T1.

tender root
#

Been wondering, should the duplexes still make the valve gear sound that the default S282 makes?

ornate spindle
#

I mean you could slightly lower the chuffing sound

#

The pitch I mean

#

Unless it doesn’t use vented steam

tender root
#

it doesn't use steam, it's just the sound of the walschaerts valve gear clinking

ornate spindle
#

No I mean for the actual chuffing

tender root
#

Well I was wondering about the valve gear sound

ornate spindle
#

Hmmm

tender root
#

the sound that people confuse with the "cylinder's got too much water" sound

ornate spindle
#

I’d say yes for the people who are big train nerds and would appreciate the different

tender root
#

as in, yes, the duplexes shouldn't have it?

Do u plan to go past a 4-4-4-4?

ornate spindle
#

But the drivers would be tiny

#

Tinnnnyyyyy

#

I mean if you look here

#

I’m not actually too sure how much space there would be

#

Might be able to pull off a 2-4-6-0

#

Which…. Did exist?????

#

Huh.

tender root
#

I was considering 2-6-6-2 and 2-4-6-0. Not sure if anyone ever made a 2-6-6-2 duplex (there were definitely articulated 2-6-6-2's, but no duplex ones)

#

For now it will just be 2-4-4-2 and 4-4-4-4

#

actually I don't think anyone has ever made a 2-4-4-2 duplex either, but it looks a bit better than the 4-4-4-4

#

The pennsy also made a 6-4-4-6, a 4-4-6-4, and a 4-6-4-4, but all three of those would be pretty tricky to fit into the game

Nvm s1 has 84 t1 with 80

tender root
#

Even if they had the same driver size, there's no way I could fit 3 leading axles and 3 trailing axles under the S282 without extending it somehow

#

Or decreasing the driver size to make room for the leading and trailing axles. But it would feel weird to make an S1 with, like, 48" drivers

#

Keep in mind the vanilla S282 has 56" drivers. Shows you how massive the T1 and S1 were

I Do wonder when T1 Streamlining will be made for the SH282

hybrid silo
ornate spindle
#

compared to just...

#

making a mesh to put over the loco?

hybrid silo
#

It won’t look right. The T1 is physically larger than the S282. And as far as modders making a whole locomotive, there’s modders doing that in the mod development thread right now. I don’t have the time unfortunately to learn the ins and outs from scratch 😦 or I’d give it a crack for you.

ornate spindle
#

Making a whole engine (which can't even really be put into the game) compared to a fun addition to the SH282 seems overkill.

hybrid silo
#

I suppose you could, but you’d have to get all the proportions to look right.

ornate spindle
#

I mean, its techinally already been done.

#

The S282Tweaks exist.

#

and it echos the S1

hybrid silo
#

I’ll have to have a look 🙂

ornate spindle
#

I just meant something similar,

#

Even without the duplex arrangment

#

Having a streamlined SH282 sounds fun

hybrid silo
#

I did read somewhere that Derail Valley is narrow gauge?

ornate spindle
#

....it shouldn't be?

#

Last I checked its standard gauge.

#

it just has a diffrent loading gauge.

hybrid silo
#

Thanks 🙂 wasn’t sure. I’ll have a look at the S282 tweaks mod and try and change my way of looking at putting a T1 style body on the S282. In the real world, South Australian Railways did build a loco in the style of the T1, the 520 class, so I guess there is precedent.

ornate spindle
#

I mean it is the same logic as the reason why I wanted this mod to exist,

#

Of course you could just 'model the locomotive you want..' but for people that don't want to model a whole locomotive, or people that want the SH282 Itself to have those wheel arangments

#

They can.

#

If someone wants a German pacific? now they can grab a German skin of the SH282, and then use a smoke deflector mod and this mod

#

Wether if be people want a german locomotive that isn't a mod, or people want to see the SH282 look more german,

#

they can.

hybrid silo
#

I’ll have to try it 🙂

ornate spindle
#

I’d find the mod for you but I don’t actually know where to start,

#

Just ask around in mod’s discussion,

#

Or look in one of these posts

#

Actually…

#

Wait no found it.

#

If someone doesn’t make a T1 streamline for the SH282

#

I’m definitely using this,

ornate spindle
#

@tender root Question will the duplexes have a higher speed?

tender root
#

No, the wheel size will be the same as the regular S282 so the top speed should be the same

ornate spindle
#

So they just... pull things faster?

solid elbow
#

More power, not more speed

tender root
#

They can pull more without wheelslip

ornate spindle
#

Wait wait-

#

Having two extra sets of pistons doesn't make it faster?

solid elbow
#

Why would it

#

A V12 doesn’t go faster than a V6

ornate spindle
#

...

solid elbow
#

It just has more power

ornate spindle
#

It makes perfect sence to?

solid elbow
#

Two MUed DE6es won’t go double the speed

#

Even though they act as one engine

ornate spindle
#

they dont????

#

I thought they did?

solid elbow
#

You won’t go 240 just because you have 2 DE6es

ornate spindle
#

Wait does it mean that I can reach its top speed faster?

solid elbow
#

Yes

ornate spindle
#

Ah.

#

This makes sence,

solid elbow
#

But it doesn’t make the top speed faster

ornate spindle
#

what is the SH282's top speed anyway

solid elbow
#

120ish

ornate spindle
#

The speedo said-

#

ah,

#

has anyone actually reached that?

solid elbow
#

120?

ornate spindle
#

((without death

solid elbow
#

Yes

ornate spindle
solid elbow
#

I do that whenever I can

ornate spindle
#

((on the vanilla map?

solid elbow
#

Gotta get that bonus time ya know

ornate spindle
#

I've never been able to get it up to 120,

ornate spindle
#

100 at most,

#

80 usually,

solid elbow
#

It is hard to hit 120 with a load that’s close to tonnage

ornate spindle
#

Ah,

solid elbow
#

But it is possible

ornate spindle
#

That explains it,

#

I was pulling 690t

solid elbow
#

That’s basically nothing for the S282

#

Tonnage for it would be between 1200 and 2000t, depending on the grade

ornate spindle
#

forgot a zero there,

solid elbow
#

Still not a lot

#

I have hauled close to 2000t a few times

ornate spindle
#

Then explain why I couldn't get up the +3.5 grade

solid elbow
#

Bad firing and steam management I guess

ornate spindle
solid elbow
#

Cutoff is a powerful tool if you know how to use it well

ornate spindle
#

Maintaning 12.5 bars?

#

or having the cutoff at 100

solid elbow
#

The simplest way of doing things is to just keep shoveling coal and the cutoff full forward

ornate spindle
#

I usually try to maintain 12.5 bars while having the cutoff as full as you can,

solid elbow
#

Although that uses much more coal and water than necessary

ornate spindle
#

and its 'slower'

solid elbow
#

It uses more resources

ornate spindle
#

It does,

solid elbow
#

That’s basically it

ornate spindle
#

...

#

So they were lying to me?

#

riding at 6 bars at high speed is fine?

solid elbow
#

No it’s not

#

14 bar is the maximum, and ideally you want to stay at that

#

Always

ornate spindle
#

Its 13.

#

The safety blows at 13 bars

solid elbow
#

Then I guess it’s the S060 that pops at 14

ornate spindle
#

Sounds about right,

#

Its always the little ones that explode

ornate spindle
solid elbow
#

But for more efficient steam usage: full cutoff uses much steam and gives you much power, close to center uses much less steam but uses it more, allowing you to go faster

#

Usually I try to get to full throttle as fast as possible and then run the engine using only the cutoff

#

That’s how real engines are run

ornate spindle
#

So how do I go fast?

solid elbow
#

Full throttle and cutoff as close to center as you can get it without decelerating

ornate spindle
#

Even if it keeps popping the safety valve?

solid elbow
#

Yes

#

Popping the safety means you are at full pressure

#

Which you basically always want to be at

ornate spindle
#

So opening the cutoff to stop it from constantly blowing is a bad idea?

solid elbow
#

Not necessarily

ornate spindle
#

Isn’t that technically wasteful?

solid elbow
#

It is

ornate spindle
#

Your just letting steam constantly blow,

solid elbow
#

If the safety pops a lot, throw less coal in the fire

ornate spindle
#

So when I have my cutoff at half forward at 12 bars

#

That’s bad?

solid elbow
#

Again, not necessarily

#

It’s a thing of experience, really

ornate spindle
#

…using all that logic,

#

Why wouldn’t the duplex be as fast as something like the T1?

solid elbow
#

Driver size

ornate spindle
#

…wait really?

solid elbow
#

Yes

ornate spindle
#

That’s it?

#

That’s the key to speed?

solid elbow
#

It is

ornate spindle
#

#

Not how many revolutions you can make per minute?

solid elbow
#

Nope

#

There is an upper limit for that, but it depends on how well the connecting rods are built

ornate spindle
#

So even with several pairs of drivers on a duplex.

#

Spinning.

#

As fast as possible.

#

It still won’t be faster?

solid elbow
#

Not as long as the wheels are bigger

ornate spindle
#

So with this final logic,

#

Would I not pull a load faster in a duplex then a normal SH282?

solid elbow
#

Nope

#

But you could pull heavier loads

ornate spindle
#

#

That doesn’t make sense.

solid elbow
#

It does

ornate spindle
#

If a SH282 was pulling a 17 ton load

#

Would a duplex not pull that faster?

solid elbow
#

No

#

Assuming the wheels are the same size

ornate spindle
#

What about a 20 ton load

solid elbow
#

Same thing

#

It just changes how much time it will take to reach the speed

ornate spindle
#

If you give the SH282 a load it can’t pull

solid elbow
#

Then it won’t move

ornate spindle
#

Would a duplex not pull it faster?

solid elbow
#

The duplex could pull a load that would be too heavy for the S282

#

But not faster

ornate spindle
#

So would it not technically be pulling the load faster than a SH282 could?

solid elbow
#

No, why would it?

#

It will pull a load at the same top speed

ornate spindle
#

Is 0kph not slower then literally any other speed?

solid elbow
#

Well yeah

#

But we’re talking about top speed

ornate spindle
solid elbow
#

Oh

ornate spindle
#

Would I not be able to to achieve the SH282’s topspeed in the duplex effortlessly?

#

It would be easier to pull loads

solid elbow
#

Yes

ornate spindle
#

And I would be able to reach that top speed.

#

Faster.

solid elbow
#

Yes

#

Acceleration would be greater

ornate spindle
#

So is a Duplex not

#

Faster

solid elbow
#

It isn’t

ornate spindle
#

Then a S-

#

The SH282’s top speed is limited by how much it is pulling.

solid elbow
#

No

#

It’s limited by driver size

#

Of course, it will accelerate slower with bigger loads

#

But it will eventually reach its top speed

ornate spindle
#

But would it would not reach it top speed

solid elbow
#

It would

#

It would just take more time

ornate spindle
#

In a perfect world?

solid elbow
#

Even in an imperfect world

ornate spindle
#

But everything isn’t perfectly levelled.

solid elbow
#

True

#

Assuming the track is flat, regardless of weight (of course if it is actually below tonnage) both the S282 and the duplex would reach the same top speed

#

The duplex would achieve it faster though

ornate spindle
#

Why would it not be faster?

solid elbow
#

Because of driver size, again

ornate spindle
#

Even with more steam flowing into the pistons per pistons?

#

That adds, nothing?

solid elbow
#

That just gives more power

plush kraken
#

beef has said it is DRIVER SIZE

#

duplexs have more power

#

not speed

#

it aint that hard to understand and read

ornate spindle
#

Would this power not in turn give more speed?

plush kraken
#

no

solid elbow
#

No

plush kraken
#

ffs

#

why you no listen

solid elbow
#

Speed and power aren’t always linked

plush kraken
#

there is a certain rpm, loco drivers can operate without throwing rods

#

large drivers means less rpm per steam usage

#

the can go faster without wrecking itself

ornate spindle
#

But DV doesn’t simulate that.

plush kraken
#

no

#

but it does simulate the max speed part

solid elbow
#

Self destruction? No. Driver size mattering? Yes.

ornate spindle
#

So would having more power not contribute to high rpms?

plush kraken
solid elbow
solid elbow
#

So no

ornate spindle
#

It feels like school has failed me.

solid elbow
#

It’s physics

#

It ain’t black magic

gusty kestrel
#

The vice versa with the same thing, you get more torque, and less speed.

#

If I am remembering that right.

#

If I'm wrong on anything, please correct me

solid elbow
gusty kestrel
#

Huh. I was thinking it went by similar rules as gearing, I guess not.

solid elbow
#

The factor that limits how fast an engine can go is the driver size

hybrid silo
# plush kraken the can go faster without wrecking itself

500-550 rpm apparently in real locos. If you calculate it out Mallard was pushing 529rpm when she set the record of 126mph and she broke down doing that. For the Doctor, think of driver size like gearing in a car. My Ute could theoretically pull 6 tons but it would have to do so in 1st gear (small drivers, high tractive effort, low top speed at 550 rpm or revolutions per minute of those drivers). Now I could not start that same train in 6th gear at all (larger drivers), but I could start half ton load that way and accelerate it to 100kmh, like a passenger steam locomotive with large drivers (high gear). I can attain a higher speed with larger drivers but my pulling power is lower. This is why freight steam locomotives have lower top speeds, higher tractive efforts and therefore more pulling power for large freight trains, than their high top speed, lower tractive effort passenger train breathren. Does that make sense?

plush kraken
#

yeah but they can throw rods if they get too fast

hybrid silo
# plush kraken yeah but they can throw rods if they get too fast

Yes they can (Happened in a catastrophic way to a Milwaukee Road Class F7, which were likely faster than Mallard but never officially timed) but the physical rpm limit for a steam locomotive due to the way steam flows, expands and reacts in a steam engine is 500-550rpm. If you’re pushing beyond that, then you’re out of control running downhill with gravity taking charge, or you’ve implemented Chapelon and Portas ideas in a modern clean sheet steam locomotive and found a way to beat physics. Failing that you increase driver size to get a higher top speed.

Anyone got estimated tonnage for the duplex yet? lol

omg, 4-0-4: drivers not found lol

ornate spindle
#

How did you manage that?

gusty kestrel
#

it was the last option, after the 4-4-4-4

gusty kestrel
#

I found a bug! or two

#

So, I applied throttle with the 4-0-4 no drivers, then switched to the duplex, and the throttle wouldnt apply throttle no matter how far I moved it. It then suddenly fixed itself when I messed with the reverser, and there was apparently water in the cylinders, and I busted the back end of the rear right cylinder before I could get the cylinder cocks open as the locomotive launched forward, and turns out the busted cylinder effect for that cylinder is underneath the cab

#

also, the tender derails before the 4-4-4-4 does, I got to going 60 out of harbor on the uphill 40.

broken lion
#

Lmao

#

How slippery is this boi BTW

gusty kestrel
#

no clue, I was trying to get the auxillary tender hooked up, and I had no weight to speak of when hell broke loose

#

she almost made it through this 40 curve going 80, and derailed as she was coming out of it

#

I know I was going 60 through the inital 40 section when the tender said screw it

#

So, I guess everything else will derail long before the locomotive does

#

70! the locomotive can do 70 around a 40, but no more

#

with the 4 pilot and 4 trailing wheels

#

roughly

#

lost the tender just before the last switch between the southernmost track between sawmill and harbor and the loop, ran out of water and coal, derailed twice, and still made it to the summit of the loop

#

I was also not being effecent, I just hail mary'ed it all the way

It makes things smoother,

tender root
tender root
#

Which means the 4-4-4-4 is about as slippery as the 4-4-4

shadow raft
#

I'd expect the extra power from using just 2 drivers with the same cylinder size would make it easier to slip.

#

The 4-4-4-4 would be applying twice as much power to the rails as the 4-4-4 at a given time.

Are you on Windows?

Actually side note, why does it seem the duplex builds steam faster?

#

Is that intentional?

silver prairie
tender root
ornate spindle
#

Odd,

tender root
#

There's more airflow through the exhaust, so it will be a hotter fire once you get going

ornate spindle
#

Perhaps that’s it?

#

But it definitely feels like it’s easier to build steam,

tender root
#

But that's only when using steam - when stationary or coasting, it should be the same as the vanilla S282

ornate spindle
#

Well, that’s not what happening,

#

I’ll have to run more tests, but it definitely feels like I’m gaining steam faster

#

Perhaps it has something to do with valve gear?

#

Because not only can I keep the cutoff closer to the corner, I can do so without even worrying about killing the steam pressure,

gusty kestrel
#

Ok, there is currently only one issue I have with the duplexes, that being the light that illuminates the drivers cant illuminate the front drivers, and barely does anything for the rear drivers

#

two ideas to fix this could be to either add and move the current driver light, or maybe add platforms to put lanterns?
