Train Kit

This simulation game is part Minecraft, part virtual reality, and all fun, despite its minor limitations. Creating your landscape and setting your trains in motion is consistently absorbing and lets parents and kids work together to problem-solve to make their trains go as far and fast as possible. It's especially fun to get your train moving and tap the video-camera button, which gives you a rider's view as the train moves along your creation.

One downside is that if you place your trees or windmills too close to the tracks, your trains may knock them over or push them along. Also, since you can't rotate objects, if you'd like the road to bend to the left, you have to select the particular shape you need. It's also too bad that you can't save multiple landscapes for later use and that there aren't human characters to play with, but aside from these minor complaints, Train Kit does a nice job of providing the fun of a traditional train set and adds the cool on-screen feature of being able to virtually ride the train, so for families without the space or funds for elaborate setups, this app has a lot to offer.
