Hi guys! in this video we have a discovery train that we have to build. This steam engine toy train has real steam and has lights and sounds. We can modify this train toy and make it motorized on lego tracks. We use lego train parts to modify this train and make it motorized. We then put the discovery train on the train tracks and take out our lego mta subway train and drive on the tracks. We drive both trains at the same time and even use our lego high speed train to make crashes and fun. We have fun lego subway train crashes and drive around lego train tracks.
