I was wondering if we could have a 12 car of the class 377 on the timetable from Brighton to Eastbourne as a express and back again so we and maybe have a 4 car class 377 to Eastbourne and then connect a 4 car to 8 car to a 12 car depending if we would like a express and maybe have a certain time and maybe have a working timetable with station announcements and maybe get more AI trains so it can be more realistic please
Easiest way of adding 12 cars, whilst still making it realistic, would be to add the London Victoria services running as 1FXX.
