Just spawned at Reigate on foot at platform 1 and found this: On the left hand side there's a class 166 that after few minutes departed southbound. On the right side there's a class https://100001.onl/ https://1921681254.mx/ 377 showing "not in service" on the display but doors were open. The strange thing is that both trains were on the same tracks. Before listing this as a bug, is this something normal on BML in real life or it's indeed a bug?
Just to be clear, this is Redhill, not Reigate. This is a real occurrence as the GWR services head to Gatwick and/or Reading while the Southern 377 departs later on the service to Tonbridge. They simultaneously use the terminating platform 1 as it is the only one to feature buffers which makes sense as they remain out of the way for the through-platform services to/from London. Just to be clear, GWR also use Platform 0, but Tonbridge is normally just on 1.
