Interchange in the middle

Entering/Exit

the useless expensive solution but working perfectly : make a 4 track circuit with 4 lines ! :

but in case of a 2 track circuit  :
with opposite direction for each couple of platform:

with same direction for each couple of plaftorm  :

as you can see , the station in the right is doing exactly what i want , but the station in the left keep using 1 platform for the “blue / yellow” line

it’s really anoying , you need to have exactly the same track lenght for each stations , and of course , the same speed limit , if not , the game use the same station , even if there is a train already waiting

and sometime , game reset the station , even if you replace a track , pouf , everything is broken
