I agree with the others here. You've got other problems outside of just Trainz having issues. Please post your system specifications to let us know what hardware (the physical PC) and software (Windows version - XP, Vista, W7, etc.). This will help us help you with your problem.
If anything your system may be overheating as that will cause a BSOD. Check that your case is clean, well ventilated and your fans are working properly.
