Mighty Mac

Mighty Mac is a Double-ended Fairlie locomotive, and the newest addition to the Skarloey Railway. Despite the opposing personalities of the two ends, they are technically one engine, painted a rich royal blue with gold and orange stripes. Mighty is the older of the two, and is distinguished by a small flick of hair. Mac is the younger half, and is distinguished by his youthful features and freckled cheeks.

Prior to their adoption into the Skarloey family, Mighty Mac had only ever worked in the shunting yards. Their lack of knowledge beyond their boundaries created much conflict between the two halves (for example, which end is in charge of doing what), which places themselves and their passengers in great danger whilst running an important errand. But with advice from Thomas in mind, they were able to complete their task and realise the value of working as one.

Mighty Mac made their debut in Series 9 of Thomas & Friends, in an episode of the same name. Since their initial appearance they have had a number of cameos, but have not been the featured characters in any subsequent stories. They have not appeared in The Railway Series books.
