Yes. It is an inverse universe as far as DTG are concerned 37, 40, 45 and blue 47 SHOULDN'T be on EC. Nice idea to prove it can be done or rub it in your face (no headlight, wrong era warning flashes for OHE)... 37, 40, 45, 66 and HST could be on WSR (as you can conceivably run ANYTHING on a preserved line). 31 should be on NTP 33 should be on EC (IT'S a SR loco) Green 47 and 52 should be on GWE... ("North Star" was a WR 'namer' when named 47's were small in number). Heavy Freight Pack vacuum braked van could be on WSR as demonstration freight. JNA hopper off EC should also be on GWE as Acton Yard is where working on EC originates from!
