After the many positive reviews of Pro Train 14 with the Frankfurt main station - Giessen - Kassel also I bought this addon for Microsoft Train Simulator (MSTS). The landscape is very well represented on the current technical conditions. The trains have a good design (VA ET 423). However, I can only again stress that the time of MSTS and its few functions (open, no doors, no attendant, no Sifa and Indusi, no driver position change) has expired. Although the program Pro Train Perfect (separate railway Simulator) has almost all these functions, but it is not better because of the poor implementation and landscaping. I'm waiting for finally a realistic Zugsimulato is developed and no longer add-ons are created for MSTS.
For true fans of MSTS but it is a must to buy this AddOn because this is still the best route for the MSTS.
