Taking you back to the days of trainsets running around the living room floor, this PC implementation of a childhood (and grown-up) favourite allows you to lay track, choose engines and carriages and add scenery, all by dragging and dropping from menus to the main window. Items click into place when dropped near a valid location, furniture in the room can be moved and all layouts and trainset combinations are inifinitely reworkable. Then you can run trains between stations, over bridges, and round layouts created by your own imagination.
