— Mighty Mac

Mighty Mac is the fifth (fourth in Australia) episode of the ninth season.


During the height of the busy Summer season, the Thin Controller purchases a new engine for his railway. Thomas meets the new engine at the Transfer Yards and the new engine reveals himself as Mighty at one end and Mac at the other. Thomas is surprised as he has never seen such an unusual engine before. Then the Thin Controller tells Mighty Mac to take holidaymakers to the campsite in the mountains. However, there are many tracks between the passengers and Mighty Mac, who are nervous as they have only worked in the shunting yards. Thomas advises them to look where they want to go and follow the track that will take them there. Mighty sets off, but then Mac takes the lead, thinking his way is quicker. As Mighty and Mac fight over who should take the lead, they end up going in all sorts of directions, even going on the turntable. As a result of their leadership battle, they end up back where they started and nowhere near the holidaymakers at all, making Mr. Percival very cross.

Eventually, Mighty Mac sets off with the holidaymakers. However, their feud is far from over, as they argue at junctions on which way to go. Mighty pulls one way and then Mac pulls the other. All of this is making an uncomfortable ride for the holidaymakers and they end up at a dead end. The holidaymakers are cross and Mighty and Mac blame each other. This results in an accident, as they push the coach off the rails and into a giant, solid rock on a bottom cliff of the mountain. This triggers a rockslide and it blocks their path. Mighty and Mac now realise how silly they have been.

The holidaymakers set to work to getting their coach back on the rails and soon it is back on track. Impressed by this, Mighty Mac work together to shift the rocks out of the way and then collect their coach. They see the flag of the campsite high above them. Remembering Thomas' advice, they set off for the campsite. After they bring the holidaymakers to the campsite, Mighty and Mac set off for home. Mighty and Mac both agree that working together makes them a Really Useful Engine.
