Mighty Mac is a double-ended Fairlie locomotive. Mighty is the "older" of the 2 and is distinguished by a small flick of hair. Mac is the "younger" half and is distinguished by his youthful features, round nose, and freckled cheeks.


Mighty Mac is 2 engines in 1! He is Mighty on 1 end and Mac on the other making him one of the most unusual engines working on the Sodor Narrow Gauge Railway. When Mighty and Mac work together, Mighty Mac is the strongest engine on the Railway. But when they don’t, Mighty and Mac pull each other backwards and forwards, only to end up right where they began.[1]

Mighty Mac are a Double-Fairlie locomotive on the Skarloey Railway and they had only worked in the shunting yards. Their lack of knowledge beyond their boundaries created much conflict between the 2 halves, which placed 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 is based on Double Fairlie locomotive of the Ffestiniog Railway with added bufferbeams with low-set buffers and couplings.

Trivia Edit

  • Despite the opposing personalities of the 2 ends, they are technically 1 engine.
