A couple of Saturdays ago, my friend caught the Northern service back to Barnsley from Sheffield having visited me for the day - bog standard express service with a 158. On arriving at Meadowhall, the woman sat next to her noted that the departure boards announced that the train would be routed via Wakefield Westgate for some reason or other, and would completely miss out Barnsley and Kirkgate. They asked the TTI what was going on, and he had no idea, telling them to go and find out on the platforms, and it was a few minutes before it was even officially announced.
My friend doesn't cope very well with situations like this and she phoned me in a panic. Luckily, I was able to use RTT to help her get home as Northern Rail weren't much use.
Instances like this are not uncommon, and it's just pathetic.
