5x15 - Thomas & Friends

Whilst waiting for his fish vans to be loaded up, a crate of fish is accidentally dropped on poor Thomas! On the way to the docks, Thomas notices that the coastal line is damaged, and on his arrival with the "Flying Kipper" trucks which are to be passed on for Henry to pull, Henry teases him about his fishy smell. Then when Henry heads off, the signalman is unaware till too late that he has accidentally switched the train onto the damaged coastal line, which won't be able to take Henry's weight for sure!
