Just been on the following service: http://www.realtimetrains.co.uk/train/G19771/2019/05/11/advanced We skipped South Croydon, a scheduled stop. This was apparently unplanned. A group of approx. 15 passengers caught up with the guard at Sanderstead, who was very polite and spoke to control, who told us we'd just have to walk back. I know the distance between these two stops is not vast - and as it turns out there was one more bus left for the evening back towards town - but what *should* have been done?
