Dovetail Games has released some information on Train Simulator 2017 (TS2017). The annual iteration of the existing TSX core engine will include routes from Germany, North America, Great Britain and France (Hamburg Lubeck, North Jersey Coast Line,LGV Marseille - Avignon and South Wales Coastal).
Further in the future, plans for Train Sim World have been announced. This new sim will be base on Unreal Engine 4 (UE4), offering new levels of realism. The video shows samples of what this will look like.
As part of this, there will shortly be available a TS2017 Pioneers Edition with two additional routes, Semmeringbahn and Train Sim World: CSX Heavy Haul Beta. This will allow users an early look at what Train Sim World has to offer.
