Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A Fairlie is a type of articulated steam locomotive that has the driving wheels on bogies. The locomotive may be double-ended or single ended. Fairlies are most associated with the Ffestiniog Railway in Wales. While the Fairlie locomotive has all but disappeared, the vast majority of diesel and electric locomotives in the world today follow a form not too dissimilar from Fairlies two power trucks with all axles driven, and many also follow Fairlie's idea of being double-ended, capable of being driven equally well in both directions. The Fairlie was invented and patented by the Scottish engineer Robert Francis Fairlie in 1864. He had become convinced that the conventional pattern of locomotive was seriously deficient; they wasted weight on unpowered wheels and on a tender that did nothing but carry fuel and water without contributing to the locomotive's adhesive weight. Furthermore, the standard locomotive had a front and back, and was not intended for prolonged driving in reverse, thus requiring a turntable or wye at every terminus. Fairlie's answer was a double-ended steam locomotive, carrying all its fuel and water aboard the locomotive and with every axle driven.
