Isle of Man Railway rolling stock

The rolling stock used on the Isle of Man Railway today is entirely original. Although the number of serviceable carriages dropped from an original total of 75 to as low as 14, this total is once again increasing due to recent rebuilds. The 3 ft (914 mm) gauge railway has been provided with a variety of stock from different manufacturers over its time. Types of coaches were categorized according to a lettering system: the original four-wheeled coaches were designated as A, B, C, and D types, and so on. The F prefix encompassed all bogie vehicles, including conversions from the A-D series. Letters G-M denoted goods stock, while N referred to ex-Manx Northern Railway six-wheel carriages.
