Mighty Mac

Mighty and Mac are a double-ended Fairlie duplex locomotive, 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. 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 Lo
