I just installed the game myself on Win7 64-bit and it does the same for me. I've let it sit there for a good 20 minutes, and it's doing not much. Is this normal for a first run?
Every time I open trainz, it says that my computer is not able to work with the simulator because my video card is out of date and that i don't have directX9. I tried all those but still can't get it to work. :'(
