3D Ultra Lionel Traintown is a 3rd person railroading game by Sierra Entertainment. It consists of train layouts, some of which the player can edit. Some of the locomotives include: Union Pacific EMD SW1500 switcher, an Atchison, Topeka and Santa Fe Railway F3A diesel locomotive (usually used to pull passenger trains), a generic 2-8-0 steam locomotive, and a 1950s passenger railcar. 3D Ultra Lionel Traintown Deluxe succeeded this game.
