At East Croydon, the departure screens on the platforms have a very annoying habit of resetting to the beginning of the list of station stops BEFORE the previous cycle has finished. You never get to the end of the message.
In this example, which shows the screen on platform 3 for the five minutes before the arrival of the Eastbourne & Ore train (speeded up before the train arrives) passengers for Collington never get to find out which part of the train they should be in. They only find out from the audible announcement just before the train departs!
