Yep, WMR and LNWR are subbrands for the (badly named) West Midlands Trains.No one is sub leasing anything to anyone... its the same TOC! They just have subbrands for the routes.
The ticketing system can't handle this so all tickets say West Midlands Trains, issue for occasional travelers who interpret them as West Midlands Railway only and not WMR/LNWR. Naming the operator WMR & LNWR in the ticketing system would have solved this.
Back to this thread - same company, the 319s needed replacing ASAP and sooner than the 323s.
24m cars, so 72m for a 3-car unit. About the length of a 3.5-car 350.And - I could be wrong - but I'm pretty sure all the 730s much like the majority of the AC Aventras are 23-24m long compared to the 19-20m 4 car fleets. So a 6 car is not too far off the length of a 8 car 350 / 319.
