The Mighty Machines are hard at work making tracks from the train yard to the city, and on the highway! It all starts with the tough trains that haul cars and freight across the country. It's no easy job to get them chuggin'! Then, Buddy the Bus shows us how he and his friends get people to work and school each day! The 'O' trains, the GO trains, the subway trains and the street cars all rumble down the rails to do their part! Dig it out over here; pile it up over there! Life is a highway for Sammy the big orange shovel, Dozer and Scooper. They're all pitching in to build a new road. So many Mighty Machines are needed to roll out a road for all the cars, trucks and buses that travel each day. All aboard for an adventure in railways and roadways!
