3D Ultra Lionel Traintown was released by Sierra in 1999. It's a third person
railroading game. It's sequel, Deluxe, was released in 2000. If you have one or
both of these games, you're really lucky! Me, I got the game back when I was
young and I had a lot of fun with it, and it became my favorite train
simulation game. There's others like Lego Loco, Thomas the Tank Engine, Lionel
Trains Trains-Con!, Trainz, etc., but Traintown and Traintown Deluxe are the
main focus here. It may be simple, but it gets harder as the game progresses.

A port was planned for the Sega Dreamcast, but was cancelled for unknown reasons.
