Having used tsw for a good few months now, I really think there is a need for a route with fewer point to point operations.... Now, within the route lengths could it be possible to have a route that contains a TMD a colliery and a power station that runs all around the clock. My uncle knew someone who worked at shirebrook TMD so I got a tour once (around 1987) and it was just so different to other railfreight operations. Very cool 56's and 58's. And the operations actually happen within a feasible size for tsw. The only draw backs would be freight only, and being able to model from archive imagery....
I've been thinking along similar lines for a while but a bit further south. I'm going to say no more as I may well build it when we get the editor.
