تعريف ومعنى "Fairlie locomotive"

What is a "Fairlie locomotive"?

A Fairlie locomotive is a type of steam locomotive with a unique design, featuring two sets of driving wheels, one at each end, and a central boiler located between them. This design gives the locomotive greater flexibility, allowing it to navigate tight curves on narrow tracks more easily. The Fairlie locomotive was particularly useful in areas with steep and winding rail lines, often found in mountainous regions. Its ability to haul heavy loads on such tracks made it popular in places like Wales and other parts of the UK in the 19th century. Although less common today, the Fairlie locomotive remains an interesting example of early rail engineering.
