The British Rail Class 58 is a class of Co-Co diesel locomotive designed for heavy freight. The narrow body with cabs at either end led to them being given the nickname "Bone" by rail enthusiasts The loco add on featured in tees valley line will have the rail-freight livery the same as the class 20 already in the game these will run 46 services along the route but if you own the class 31 you can increase it to 61 they go from lackenby steel works to Redcar ore terminal and eaglescliffe to Redcar 43 of these services will be substituting for the class 37
Much as I would like to see more BR Traction these never saw service in the North East of England, more at home on MGR (Coal) from Toton area around the East Midlands, they did sometimes venture off region but not for long. Bit more travelled after Privatisation with EWS but not to the North East still. Class 56 would be more at home or 47 for that matter of which Thornaby had an allocation.
Class 56 would be OK for NTP also. Can see one appearing one day and they still have a handful operating on todays railways.
Not when the route was set, but the route was released in 2019, 2 years have passed, this brings us firmly to the introduction of the Class 60 with the route date now being somewhere in 1991
That should work and if DTG needs a working one to measure and get proper recording and Drivers Cab it's going to be located in Leicester lip Depot. This one is in British Railways blue
