Is this the most efficent way to signal this intersection?

#

#

looks like a bit of a mess

#

in this upper area, you can move the rail signal earlier and remove the chain
the other chain can become a rail signal

#

Yeah, looks like you're better off designing a T or Y intersection and using that

digital basalt Mar 19, 2025, 9:13 PM

#

in the bottom right you have a random chain after a merge that you can remove

#

you're allowing trains to stop in this crossing - normally people want to stop trains from being able to stop there, so it's always open for other paths

#

also not sure what purpose you have for these yellow chains

#

ideally i'd like them to exit the junction 100% of the time

#

i've made the modifications you specified

digital basalt Mar 19, 2025, 9:16 PM

#

have an updated image?

#

#

i'm concerned about the lower track acting as part of the junction when a train is on it

#

would a signal help here?

#

#

something like this

digital basalt Mar 19, 2025, 9:20 PM

#

can add chains here

#

since the left portion is bidirectional for a bit, doesn't look like enough space for a train

#

and the upper part also doesn't have enough space for a train

#

done

digital basalt Mar 19, 2025, 9:21 PM

#

and then ideally change this rail signal to a chain

brisk fox Mar 19, 2025, 9:22 PM

#

done

#

#

thank you for your help

@brisk fox did you do this one?

brisk fox Mar 19, 2025, 9:24 PM

#

yes

#

fiery eagle Mar 19, 2025, 9:25 PM

#

Ah you just didn't move it

fiery eagle Mar 19, 2025, 9:26 PM

#

brisk fox

#

This can be rail as long as a whole train can stop at the next signal and not block the intersection

brisk fox Mar 19, 2025, 9:27 PM

#

it can't, it's 4 long

fiery eagle Mar 19, 2025, 9:27 PM

#

Going left?

brisk fox Mar 19, 2025, 9:27 PM

#

no right

fiery eagle Mar 19, 2025, 9:28 PM

#

Well that signal is for trains going left

#

You have left hand drive pretty much

brisk fox Mar 19, 2025, 9:28 PM

#

yeah

#

wait i think i know what you mean

#

ok thats adjusted

#

actually you know what

#

ignore thos

#

this*

#

#

thats the end of the track

#

i have 2 signals, i want to allow trains to use the track up to the station

#

so as long as nothing is actively on the track the 2nd signal will read green

#

and allow a train up it

#

this is fine
