Supplementary to the Class 150/2 on WCL, the Class 153 in Regional Railways livery would be a good fit as a dlc. The British Rail Class 153 Super Sprinters are single-coach railcars converted from two-coach Class 155 diesel multiple units in the early 1990s. The class was intended for service on rural branch lines where passenger numbers do not justify longer trains, or to boost the capacity on trains with high passenger volume. Class 153 number 1 cab front layout as originally built by Leyland. Cab front of number 2 end as converted by Hunslet Barclay.
It would be quite unique to drive, having different style cabs at either end. Train formations would be interesting too, either working as a 1-car, 2-car or a 3-car coupled to a Class 150. Hopefully the car limit matching problem thing can be overcome for timetable substitution, or just implement a separate timetable like with the Class 313.
I think the Class 158 turned up in Cornwall later but I would still also like to see Class 158 and 159 at some point soon.
Excellent idea and you need to know these use BSI Couplers to go multiple-unit combinations with Class 150/2. Present Day use is Northern Rail if they need to combine a Manchester Victoria to Leeds City via Halifax Bradford train with a Blackpool to Leeds City Train via Hebden Bridge using Class 150/2 158 155 153 156 Calder Valley Line service
