TIL: You can have train stops with identical names and they'll act as 1 large station with multiple platforms.

I've been wondering about how it was impossible in Factorio to create true RORO stations because I've always assumed that train stop names had to be unique.

I was building a new stop for an outpost when I accidentally clicked on the list of names, while renaming the stop. Was quite surprised that the name was allowed and decided to try it out with a chain signal and some normal signals.

Was pretty shocked the trains then actually pathed themselves correctly and used the next available stop!

If you wanna give it a try: Just put a bunch of train stops in parallel and have a normal signal for their entry. 1 single chain signal will be enough on the 'main' track.

STOP1 ====N1=\
STOP2 ====N2==C====
STOP3 ====N3=/

If there's a train at STOP1, chain signal C will turn blue and signal N1 will be red. Any train coming in will then go to N2/N3 as long as their signals are green!
