The amount of short platforms on the marches!!Crewe gets a few in the week, but Nantwich is a big one now. I take the 18:30 (dont want to risk the 17:30 and the 19:30 and 20:30 are 2 or 3-car) on a weekday and that has a huge number going to Nantwich. I know it because they all have to walk forwards because only 2 carriages are platformed when it is a Mk4 set (I think).
