The problem will be the graphics because of the Intel integrated graphics chip. Trainz TS12 needs a discrete graphics card such as an NVidia or ATI (AMD) card. Some newer laptops have this graphics capability built-in, however, yours does not.
You can try running the program using Open/GL with the settings moved down to an acceptable, but very degraded performance level.
Sorry to be the barer of bad news.
As others have said, your best bet is to go with the MAC version.
