The main allocation for Monday to Thursdays is a Class 153 with a number of exceptions which are the 06:07 and 19:07 departure from Crewe as well as the 17:42 and 20:42 departures from Derby which as booked to use Class 158s.
On Fridays however the departures from Derby are: 06:40 single Class 153, 07:40 Class 158, 09:40 2x Class 153. The Friday changes were brought in as too many passengers were being left behind in the evenings at Stoke-on-Trent as many University students were using the trains.
I am not sure about weekend allocations and if there is racing on at Uttoxeter more coaches are put on.
On a recent Sunday the 1429 SOT to Derby was formed of a 158+153, normally on a weekday it is formed of a single 153. Surely there will be more use on a weekday?
Kind of related I'm sure I've heard of or seen pictures of 180's or even a HST on this route - can anyone confirm?
Never seen a Class 180 along the line although thats not to say there hasn't been one.
HSTs and Class 222 Meridians use the line if the Midlands Grand National is on at Uttoxeter or the West Coast Mainline is closed and I have seen them occasionally. A couple of years ago East Midlands Trains used 2 Class 37s and a rake of Mark 2 coaches but there were more enthusiast on the train than passengers causing severe overcrowding.
