The main freight route from Drax power station to Immingham Docks via Scunthorpe. Plenty of freight services run on this route mostly DB Cargo and GBrf class 66's running biomass wagons, but the route also includes Freightliner 66's running steel trains, Colas and DB 60's hauling petrol tanks and of course TPE 185's and Northern 142's running along the route. Potential for tons of scenarios; especially if Scunthorpe steel works is included. Maybe set the time period in the 90's and include Kellingley pit, which could also open the door for Eggborough power station too. Alternatively, the route could run from Drax to Hull, via Goole and via Selby. This could then include Ferrybridge and Milford sidings and would still offer passenger services from Northern, TPE and Hull Trains between Selby and Hull. You'd also have the added bonus of the very scenic Humber Bridge to pass under.
Definitely a route that would get my approval. Spent many a day on Barnetby station and it would be best set in the semaphore era. Wrawby Junction just doesn't look the same with colour lights.
