I propose Doncaster to York In the mid 1970s It could have all 22 BR Blue Class 55s with nameplates with some having white Finsbury Park window surrounds. York Diesel Depot and possible Doncaster Carr depots for stabling, it would be great to take control of the Napier beasts!!!!! Classes 40, 45 and 47s could be also used as an extra layer from NTP maybe even the 31 from TVL
