Mighty Mac

Mighty and Mac, collectively known as Mighty Mac are a blue double-ended Fairlie duplex engine, and conjoined twins. 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, round nose and freckled cheeks.

Despite the opposing personalities of the two ends, they are technically one engine.

Biography
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.

Personalities
Mighty Mac are two engines in one. He is Mighty on one end and Mac on the other- making them one of the most unusual engines working on the Skarloey Railway. When they work together, Mighty Mac is the strongest engine on the Railway. But when they do not, Mighty and Mac pull each other backwards and forwards, only to end up right where they began.

Basis
Mighty Mac is based on a Ffestiniog Railway Double Fairlie engine. Unlike the FR double Fairlies, Mighty Mac have added buffer beams and buffers. Little Giant shares the same class.

Mighty Mac has been modified in order to work on the Skarloey Railway. Whereas their original basis was built to 1 ft 11 1⁄2 gauge, Mighty Mac was built to 2ft 3in gauge and they have been given buffers and screwlink couplings in order to work with the other engines.

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.
