I may be wrong but I think the morning M1 (excluding Wednesdays) typically uses Solo M14PCL as I think it interworks with the S1, whereas the 15:00 from Morpeth and return is normally R222LOT. MH06WCU often tends to be on the 808 (and sometimes M1 as I may be wrong but I think it interworks with the 808 on somedays).
I'm hoping to have a ride on Optare Excel Y249DRC which they've acquired from Grand Prix Coaches, apparently they only paid £1000 for it but I've heard it's in great condition.
Versa's are supposedly arriving sometime next week.
