Canterbury Railway 0-4-2 Locomotives in New_Zealand
Class Details by Steve Llanso of Sweat House Media
Class 5 / M (Locobase 5682)
Data from Douglas Colquhoun's entries presented in the Australian national railway museum site: [
] (visited 14 October 2003). Works numbers were 740-741 in 1868, 855 in 1872, and 964, 1020 in 1874. Locobase can't place the sixth locomotive.
The New Zealand railway took delivery of three well-tankers and three side tanks over a s-year period (1868-1874). The first pair were a well tank and a side tank. Next came a well tank n 1872, then a well tank and a side tank in 1874.
Data refer to the side tankers, but the differences were confined to bunker and water capacity as well as maximum axle load (well tanks were lighter).
All of the class went across the sea to the South Australian Railway in 1880-1881 as M-class locomotives. Rebuilt in 1887-1888, these little engines carried on until 1913 (1), 1916 (1), and 1917 (3).
