Chuggington Season 4
Backup Brewster
Brewster is learning to use the mega-chug crane, but his training time is cut short when they are called away to fix some damage in a mine tunnel. As they cross the old rickety bridge it collapses, leaving Zack stranded on the other side. How will they ever reach him? Brewster has an idea. The chuggers help him transport the mega-chug crane up the steep mountain. It's a tough challenge and they nearly don't manage it, but Brewster is determined. He uses all his crane skills to lift Zack safely out of the high tunnel. Zack could not be prouder of his trainee.
