cant got it - im making two stations A anb B, 2-3 trains from A to B and place them on A. then i make B station enabled by locomotive(as item) >0 and from constant combinator trying to send on B station signal locomotive(as item) = 1 / and then all trains try to reach B - as in vanilla does. Please help

oh, i finally got it. good mode

but it seems quite instable i think

How do you managed to make it work ?
i do simple test making a loop Station A->B->C.
There are 3 station A, 1 station B and 1 station C,
And i make a junction before B so a train can pass station B, go straight to C.

In Station B i set the station condition with Locomotive signal > 0, just as instructed.
Then i connect a constant combi, outputting 1 Locomotive signal.

But all three train keep trying to reach station B., not passing just like the screenshot.

Edit :
Managed to make it work, it doesn't work because compatibility issue with other mod, namely FARL
(that i know so far).

For those who want a quick fix (in case the mod author haven't patch it), i mention how to fix it in other thread:
