Coupling

[slow willow]

Add 2 new blocks, it allowed to attach the trains between them. And a new block to auto detach them.

Basic couplers:
Attach when the tow train chock each other; And can be detach by the player whit a wrench.

Auto couplers:
Like the basic, but the player can detach the couplers from the locomotive whit a new key bind.

De-coupler block:
Place like a signale on the rail, activate by redstone. Decouple all Auto couplers passing over it.

This would make it possible to make marshalling yards!

We already have a coupling block

And as for the shunting yard thing: https://youtu.be/xj-LgAy_nPU

[slow willow]

ho ok

[slow willow]

but that's not exactly what I'm looking for, I prefer that the attachment system be closer to reality, that is to say that if two couplers touch it clings. And this does not allow to make push trains. I think my idea is not currently feasible because the wagons should keep a velocity.

[bronze island]

wait for simulated to release

then it might be possible

since you need to simulate blocks on the trains

[wicked siren]

you wouldn't need simulated for that, but it would require a significantly more complex system than the one we have right now

[hidden creek]

I would love to see this implemented. It’s much more simple and logical than the current coupling/uncoupling system, it would provide much more flexibility in Create train operations, and it would encourage more complex gameplay as a result of its ease of use. I think it would fit seamlessly into Create and believe it would be well worth the work to implement

[real elbow]

The problem is, trains already have a predefined behavior when they bump into each other (crash), and overriding that to make knuckle couplers work would be enormously complicated.

[real elbow]

I'm not saying it's not doable, but it would be very complicated.

[wicked siren]

I doubt it would be much more complex than anything else

Just give the knuckle couplers their own hit box that when it intersects with each other the trains combine and their velocities are added

[real elbow]

Ahh

[valid chasm]

Yeah but if you move to fast you trigger a crash 🤔

[bronze island]

hmm, most of the time, only one train will be moving

since you are likely to have a shunter or a transport loco disconnecting

so if it defaults to the velocity of the moving train - some speed

it could help prevent the overspeed issue?

and another thing could just give it a max speed for coupling

if the collisions generators speed above that, you get the crash result

[hidden creek]

Yeah that’s what I was thinking yesterday

[wanton lance]

I wonder if block counts * velocity can be a way to approximate momentum so the resulting speed can work like a completely inelastic collision for added realism?

[barren linden]

only when bogies hit

[hybrid phoenix]

How about there’s just a huge cargo train

And then one kid comes along

And detaches the coupling

So that the steam engine keeps going but all the other wagons are left behind

I think thats hilarious tbh XD

[valid chasm]

Not if the train is running the wagons can speed up using gravity and create problems

In Poland we had catastrophies like that

[nocturne compass]

Wouldn't it also mean trains bend on the couplings not the bogeys?

[west pond]

that wouldn't be physically possible without the bogeys moving laterally

I think the real couplers have their own pivot

[barren linden]

real

couplers

Have a pivot

[candid narwhal]

What if the weight of a cart effects the speed of how fast the freight or coaches accelerate and decelerate when not coupled to a locomotive

[barren linden]

yes

[soft valley]

I could be a block like the size of a slab and when the train hits the block it knows that it needs to connect

[vagrant barn]

I think this would be better than the current system

[normal cairn]

I agree

[strange summit]

been using the coupler blocks a lot lately on a survival server in 1.19.2 and honestly I'd absolutely love to see some kinda overhaul
main idea I've had has to do with having a shunter's pole type item that lets you click on two trains to couple em,

but. the idea of having knuckle-style couplers that also let you push trains around without colliding sounds REALLY fun, and exactly what i've been looking for.

[timid fulcrum]

would be nice to have it abit like how train sims do couplering/de-couplering
but properly need a whole rework on how the create trains works
but ability to choose what is a locomotive and what is a wagon is properly the 1st step

[bronze island]

honestly weight could be annoying since there is no weight system in minecraft rn, but used blocks could work

[normal cairn]

Maybe bogies with the control blocks are registered as the main loco while the rest are wagons?

[normal cairn]

So kinda like mixing the wrench and coupler block? Sounds viable

[strange summit]

Ya, exactly

but, ofc it'd be a seperate item since the wrench already has a use in picking up and moving trains
