Rail Works 2 - rail simulator can be downloaded here:br For all you train fans out there SKIDROW brings us RailWorks. This game is also known as Rail Simulator 2: RailWorks if you were a bit confused. Strangely enough this game uses PhysX. I really don't know how much physics trains driving on tracks needs, but I doubt it is really using all PhysX can offer. If your second love in life is trains, then I would give this one a go.
