What graphic cards did these other computers have? Curious that they all had your problem.yes they updated the drivers but i tried the game on several other computers and it didn't work either. And I even bought a new copy of Trainz thinking maybe it was something with the disc. But the new copy did the same thing.
Is anyone else using the OP's graphic card?
video card is a Vision Tek Radeon HD 5450. 4094MB Ram.
