We have some great tutorials that walk through a lot of the RailxRail Train Set app. Each tutorial is less than two minutes and you can play alongside us!

Can I hide the track or cover to get at the pieces underneath? Yes! When you are editing track layouts, you can use the Layer Toggle in the gizmo to hide the cover layer so you can get at the track, or hide both the cover and the track layers so you can fix up the houses, roads, and ground. One more tap restores all three layers so you can finish up pieces in any layer.
While you're running a train, of course, all layers are visible.

Can I group pieces of track to move or rotate them all at once? Not yet—but we're working on it!
