What does it take to bring the entire Island of Sodor Railway System to a halt? Just a crack in the track. Well, a crack in the track and some hail on rail . . . and a toad in the road, and a fuss on the bus. In fact, one thing leads to another until just about everything that can go wrong does go wrong. Luckily, there's a breakdown train with a couple of cranes that can fix a big mess (and they don't mind the rain).
