What is fairlie locomotive?

The Fairlie locomotive is a type of articulated steam locomotive that was invented by the Scottish engineer Robert F. Fairlie in the mid-1800s. These locomotives were specifically designed for use on steeply graded railways and narrow-gauge tracks.

Unlike traditional steam locomotives, Fairlie locomotives had a unique double-ended boiler and two separate engines that were connected to a central frame. This allowed the locomotive to negotiate curves and steep inclines more easily, which was particularly important for railways in mountainous regions.

The Fairlie locomotive was popular with railway companies in Britain, Australia, New Zealand, and South Africa during the late 19th and early 20th centuries. However, with the rise of diesel and electric trains, the Fairlie locomotive fell out of favor and very few of them remain in operation today.

Despite their declining popularity, Fairlie locomotives are still highly regarded among railway enthusiasts for their unique design and engineering ingenuity.
