What are your computers spec's ?

 

[CasyJ]

What version of Trainz are you running?

Hate it when that happen's....

Try turning off your anti-virus program & firewall before starting Trainz & also defrag your HDD's. C:\ & whatever HDD you have Trainz on.
That possibly might make a difference, particularly if you are trying to run Trainz on a low spec computer.
Worth a try.............
