PC game help: Trainz Railway Simulator 2004?

Question

The game I need help on is TRAINZ RAILWAY SIMULATOR 2004. I was wondering if anyone who has/had the game can help me. I want to be able to drive any train that is currently on the game, just like on TRAINZ VIRTUAL RAILWAY, where on that game you can select the train you want to drive and away to go. But on this one it wont let you, it will only let you drive one train per track. I KNOW YOU CAN CREATE YOUR OWN MAP WITH BUILDINGS AND TRACKS etc. Please help. 1st best answer will get 10points.

Answer 1

Track definition defines the trains available to use on that track. No way around it that I know of.

Of course you could load a track into the editor, add your own favourite train to it, and start the sim from there.
