The Douglas Breakwater Crane Railway was a massive self-propelled steam crane that ran the length of the original breakwater at Douglas, for the loading and unloading of vessels. It was built by Cowans, Sheldon of Carlisle (capacity 25 tons; carried on two four-wheel bogies; Works number 9057 of 1948 to Drawing 18087). The crane was owned by the Isle of Man Harbour Board and ran on 10 feet (3.05 m) gauge track, the broadest in the British Isles. It was in action until the 1970s.
