It's time for the three trainees to move up to advanced training. Wilson joins the Chug Patrol rescue squad, Brewster teams up with the Chuggineer construction crew and Speed Fleet recruits super-fast Koko. When Koko finds herself in peril, Wilson rushes to her rescue and pulls her out of a collapsing mine tunnel. Then when Emery breaks down in the forest, Chug Patroller Wilson uses his new skills to locate him with the aid of a flare and gets him back on track with a huge crane. Wilson proves that he's in control and ready to roll!
