It's winter time and icy temperatures are causing all kinds of problems throughout Chuggington. The docks are covered by thick fog, the tracks are slippery and haulers can't get in and out with their deliveries. When the town runs out of fuel and all diesel engines are grounded, it's wheels-to-the-rails as Chief Jackman and his team of brave Chug Patrollers work together to find a way to the frozen docks to retrieve fuel and get the town moving once again. In this cool new, super-sized collection of Chuggington adventures, the chuggers perform one winter rescue after another! Watch as Fletch tries to repair the much-needed lighthouse all by himself, Calley tests to become a first responder, Brewster gets closer to being a Chuggineer, and more! Your own little Chugger will discover important lessons about safety, responsibility and teamwork as they ride alongside friends like Wilson, Koko, Brewster, and Asher!
