Sun 4 Sept: Southern Trains run just one route

[ianr]

As announced during the week on the down platform indicators, there are no trains between Tulse Hill and Crystal Palace on Sunday 4 Sept.

That's not actually the whole story. The National Rail Journey Planner shows no trains at all from ED, up or down, on the Crystal Palace-London Bridge route. The full Southern engineering work details are here.

That leaves just the East Croydon branch running through ED, with trains:

To East Croydon 04 & 34 min past the hour

To London Bridge 07 & 37 min past the hour
