Do you dare to colonise a fiery meteor? DEEP SPACE SURVIVAL What will you need to add to protect your trains on a hostile planet. Add some lasers to blast dangerous meteors before they destroy your tracks. Wind turbines and solar panels will help generate power but how will you feed the occupants of your space station. 3D TRAIN DRIVER Switch to train driver view to get a first person view of your interplanetary space port as you whizz around.

Kids of all ages will love this app if they can stop a parent from playing with it.......” “This is an amazing game where you can use your imagination and create your own city with trains, bridges, archways, buildings, windmills, and so much more! Download this awesome game now!” “My four-year-old loves this game… The controls are easy enough that it’s easy to let him go with the game and even do some building with his grandparents…“ “This is a great little app. It is fun and simple to play. Almost like having one of those small wooden train sets. Easy assembly of the tracks and just drag objects to the water boundary to remove. This is a good game for little kids because there are no in app purchases, settings, feedback, connect Facebook, etc.“ “While recommended for ages 6-8, this kid-at-heart loves playing with Train Kit. The simple to use touch controls make it a joy to create train lines and diorama, then watch the trains run through your custom worlds, even in first person view.“ ABOUT OUR APPS Our range of Kit apps are designed to allow children to create fun immersive worlds to explore.
