I've had a chance to "play" with the Trainz railroad simulator game. I find the 3D amazing. I played a little with the terrain maker where you create your own world from scratch. I noticed you can choose the scale you want to model in. But the track (at least on the demo), is a point/drag/click type operation. It's not like you lay a piece, and then another piece, etc
My question is this...are there any 3rd party products/tools that allow you to import track such as Kato unitrack or other brands so that one can actually lay "virtual track" which can later be actually laid on a home layout.
