New Zealand DI class locomotive

The New Zealand DI class was a class of five diesel-electric locomotives built for New Zealand Railways by English Electric at its plant in Rocklea, Queensland, Australia. It was seen as an alternative to the DB class for lightly laid secondary and branch lines, mainly in the South Island, and had an American-style high front hood and a full adhesion Co-Co wheel arrangement. The design evolved from the Queensland Railways 1600 class, and Queensland Railways in turn ordered a development of the DI as its 1620 class. When the World Bank financed the Japanese-built DJ class in 1968, no further DI locomotives were bought. The class worked around Dunedin, Wellington and Napier, was withdrawn between 1986 and 1989, and DI 1820 survives with the Diesel Traction Group.
