There haven't been dedicated local lines to East Croydon for years - a local service has to borrow some fast track for the final approach, and there was no problem timetabling this in the past. But now with the increased number of thameslink trains, they have deliberately chosen to choke our service off.
There is a minimal service via Norwood junction, which is subject to delays, but does allow easy interchange outbound. However the policy for the return journey is to strand passengers on a central platform, remembering there are no ramps or lifts here, just an old narrow staircase, obviously ideal for wheelchairs/pushchairs, and luggage from a flight. We are better served by the bus now to get to/from E Croydon, and that is a long journey during the day.
Anyway, it doesn't take much effort to join the dots and realise they don't particularly want our local rail services at london bridge either, clogging up their lines. With trains.
