Thomas & Friends (1984)

S5E15 Something In The Air

While Thomas is at the docks waiting for his fish vans to be filled, disaster strikes when a crate of fish is dropped right on him! As he makes his way to the docks with the "Flying Kipper" trucks for Henry, he observes that the coastal line is in disrepair. Upon arrival, Henry can't resist teasing Thomas about his fishy odor. However, as Henry departs, the signalman mistakenly directs him onto the compromised coastal line, which certainly won't support Henry's weight!
