ZDSimulator, is like the equivalent of the German Zusi 3, but in Russian
I guess that if you want to get into EU locos then the only way to get a realistic simulation is by either of these two sims.
At the price point of ZDSimulator, I can safely say it´s well worth it, if you can get by the language and of course the out-dated graphics. This is the same way with Zusi 3.
Even in beginners mode, the sim puts some learning curve to it. As for the rest, well you do need your thinking cap on, and also a bit of digging around to find stuff. I tried to make it simple for you all if interested...
