no i am using ts 2010 as you can see against my username.now after posting my last comment i again drive on that route on one of the passenger session.every thing is fine and wonderful but at the end same thing happens ang again"trainz has stopped working"@kamran: Do you use the TS12? Because I have the same problem. The sessions which crashes my TS12 are all LW Bogdanka sessions. May be the crashes are a result of the script errors which occurs after the start of any sessions of this route.
