Class 57 Gwr Night Riviera

I would like a class 57 to represent the GWR Night Riviera Which could layer into GWE for part. 1 and Riviera line for part 2 it would mean you can do half of the GWR Night Riviera up to Plymouth

 

You'll need the Mk3s too !
I would love that

 

I didn’t know this but on the Mk3s’s the tail lights are built into the back of the carriage
