Four Little Engines is the 83rd episode of Thomas and Friends
Edward is on his way to the Works to be mended. He later meets a narrow gauge engine called Skarloey, who is resting in a shed and is lonely, because his friend Rheneas is going to be mended. The 2 talk for a while, until some workmen come to take Edward. Edward says goodbye and that Skarloey's railway is lovely before leaving.
Meanwhile, Sir Handel is having issues with some coaches. His punishment has ended and tries to be kind to the coaches but they refuse to trust him and become awkward and rude. When he has to stop due to a flock of sheep straying onto the line, the coaches angrily think that he deliberately bumped them, so they lurch into Sir Handel and bump him off the rails. Not even a disaster strikes and no one is hurt, but Sir Handel limps home. With no engine to take the passengers home, Skarloey volunteers and goes to fetch the coaches.
When Skarloey arrives, he scolds the coaches for their behaviour and how they could have hurt their passengers. The coaches apologise and as soon as the guard blows his whistle, Skarloey's journey begins. Skarloey stops at every station making good time until they get to a hill. Skarloey thinks it would be easy when they go down, but it is not, as his springs become weak from age and the rail joints jar his wheels. But as soon they come down the hill his springs become completely broken, tilting him on 1 side. His driver says they now need a bus to take the passengers. Skarloey refuses the idea as he is determined to get them back to the last station.
Later, James waits impatiently at the station but Skarloey makes it on time. James collects the passengers and takes them home. Everyone is pleased, but Skarloey reflects afterwards that he is in no state to pull trains, but is delighted when his driver tells him he will be mended and that he deserves it.
