How does two trains pass each other on a single track? Well, one of the trains stops completely while the other passes by. Makes sense?
This business simulator was one of the finest of its time. Lay track and build stations, make sure that the right merchandise ends up in the right city where you'll make most profit.
My favorite starting point was building a railroad from Brussel to Lille and Amsterdam. Connect it to Osnabrück and Leipzig. I usually didn't care much for the objectives. I just wanted to build a lot of railroad tracks, stations and see my trains go.
