“Due to the fact that the product that Carsten developed is very strong in terms of professional background, we decided to contact him and do Zusi with him.” “A lot of people were asking us to do some more specialised train simulation, which is not that casual, and more accurate in terms of professionals using it,” says Aerosoft head of product management Dirk Ohler. Zusi 3 – Aerosoft Edition was released in June, repackaging Hölscher’s software along with the newly-added Cologne-Düsseldorf route.

While Hölscher has primarily marketed the Zusi series to the German market himself, for Zusi 3 he teamed up with German sim developer and publisher Aerosoft, which has logged more than 25 years in the world of simulation. The game, developed by Carsten Hölscher, models more than 500km of driveable routes on the German rail network, including Cologne-Düsseldorf, the upper Ruhr valley railway, the marsh railway Heide-Westerland and the Intercity-Express (ICE) route Kassel-Göttingen. Zusi 3 is an excellent example of the latter style of professional-level train sim games.
