Bio
Prior to their adoption into the Skarloey Railway family, Mighty Mac had only 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) when they pulled their first train, 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.

Persona
Mighty Mac is two engines in one! He is Mighty on one 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.

Basis
Mighty Mac is based on a Double Fairlie locomotive of the Ffestiniog Railway with added buffer beams. A Double Fairlie locomotive from the same railway appeared in the 1979 Annual. Three of these are currently in service on the Ffestiniog, another is preserved at the National Railway Museum and another is under construction at Boston Lodge.

Livery
Mighty and Mac are painted royal blue with yellow and red lining. On Mighty's side, his cab windows and tank caps are lined with yellow, while on Mac's side, they are lined with red.

Trivia

 * Unlike most Double Fairlies, Mighty and Mac have a whistle at both ends of their model.
 * Mighty is the only engine to have what appears to be hair (besides Iron Duke's and Etienne's moustaches), though 'Arry and Bert both have 5 o'clock shadows in the form of facial hair.
 * In the eleventh season, their whistles were changed to Harvey's at a higher pitch.
 * Mighty's original whistle sound was later used for Bert, albeit at a half-step higher in pitch.
 * Mac's original whistle sound was later used for Rex.
