Mighty Mac (later re-titled Mighty and Mac Work it Out) is the thirty-seventh book in the My Thomas Story Library series.


The Island of Sodor is a popular tourist destination in the summertime and the engines are so busy that the Fat Controller has asked a new engine to come and help out. The new engine will take holidaymakers to the mountain campsite and has to be very strong as the track is steep and twisty. Thomas meets the new engine at the Transfer Yards and is surprised to see it has two faces! The engine introduces himself as Mighty Mac (one end Mighty, the other end Mac). When Mr. Percival, the Thin Controller, tells them their job, they are worried as they do not know how to get to the other side of the platform where the passengers are waiting - but Thomas is there to help and explain. He tells them to look where they want to go and follow the track that goes in that direction. But when Mighty and Mac start trying to get to the campsite, they get in an argument over which track they should take and are both puffing in different directions. This only angers Mr Percival, so Thomas shows them the way. Mighty and Mac couple onto their carriage and start the journey uphill to the campsite. But when they come to a fork in the road, they start arguing about which way to go, pushing and pulling each other onto different tracks.

But as Mighty and Mac have been too busy arguing to look where they were going, they soon go the wrong way and end up at a dead-end. Mighty and Mac start arguing about whose fault it was and are pushing and shoving each other - and accidentally knock their carriage off the rails. Now the holidaymakers are annoyed. They work together to push the carriage back onto the rails and Mighty and Mac watch them helping each other. This gives them an idea - "Let's work together!" says Mac. Mighty couples onto the carriage and this time Mac takes the lead - and they are off. The holidaymakers cheer and Mighty and Mac remember what Thomas had told them to help them find the camp site. They discover that when they work together, they can be a Really Useful Engine!
