Yeah the 3 cars have been showing up on the busy peaks already. I noticed for example on Wednesday that the 17:19 Leeds-Skipton was a 3 car, followed by the cancellation of the 17:42. Given the time of year services in the evenings can and do get very busy, and so any 3 car workings are going to put more strain on an already fractured service. And people are already noticing the shorter units, I've heard several comments along the lines of "they're making the trains smaller". I know the idea is to diagram the 331/0s away from the busy services until 6 cars can be run, but this week proves that if it can possibly happen it probably will, especially at Northern.
