My friends, in this video we will build an incredible track together with you! As many as three engines will be traveling along it at the same time! There will be tunnels, unbelievable descends and ascents, curvy bridges, criss-crosses, rail interchanges and a lot of other stuff. Right after we finish building the track there will be a competition during which we will find out which of the engines is the fastest one! It’s time to get creative, my little engineers! All aboard!
