Thomas & Friends - Season 10 Episode 6

The hill clock tower’s bell needs to be given a good polish off for the country fair. The Foreman tells Duncan to travel slowly with the bell, but Duncan ends up becoming so enraptured by the bell’s sound it makes, going along the bumpy sections of track, that he doesn’t listen. It is only when the bell flies off his flatbed truck, upon hitting a dip, that Duncan realizes he should have listened. Duncan will have to put in quite an effort to retrieve the bell – which has become dangerously stuck in a tree. Any second, it could fall.
