I have some route suggestions for Train Sim World: Xbox One Edition Extension of the Great Western Main Line to Swansea from London West Coast Main Line: London to Glasgow East Coast Main Line: London to Edinburgh Cross Country Route from Penzance to Aberdeen Hope these routes will be included on Xbox One soon.
Nice ideas but the longest route we have so far is around 45 miles to it is unlikely we will see any of these soon I would imagine.
Good idea in principle, but these very long routes - especially Penzance to Aberdeen - would need to be split up into various sections, both because of the distance involved and because of the long journey time. Perhaps a third party developer might consider creating some of these routes section by section - although it could take several years to reach production stage.
Yes it would be too long as a whole route to drive for 14 hours. The idea of splitting into different sections of the route sounds good.
