One thing that would allow us to alternate tracks for trains is island platforms right now we have this:
on a 2 track station. Passengers need to choose which platform. But if we had this:
TPT a train going to either side could be loaded. So on a 4 platform station we’d see:
TPTTPT this was 2 going in one direction and 2 going in the other direction could allow them to choose. Though, honestly it doesn’t take long to load trains, and you really shouldn’t have trains sitting there “waiting to full” so I’m not sure what the big deal is about having trains which are both stopping at the station choose their platform. and if a train is meant to bypass a station, build a bypass track and they’ll use that.
