Was on the above train today, which was meant to call at Duddeston at 1119, but I was slightly bemused to find that the train overshot the platform, with rapid deceleration only stopping the train about 200 yards past the station. The train then had to continue forward to Aston. The guard had already announced the stop for Duddeston, and could only apologize for not stopping at Duddeston. I can only imagine that as 2/3 trains on the cross city line don't stop at Duddeston, the cause for this would just be human error and the driver not realizing the train called at Duddeston until too late. What I'm wondering is does this happen often with stations that are rarely called at? And in what situation would the train be allowed to reverse back into the station?
