EMD G22CU

The EMD G22CU is a metre gauge diesel-electric locomotive designed and built by the Electro-Motive Division of General Motors and manufactured by several licensees. It was exported to many countries, including Argentina, Australia, Brazil, Egypt, Iran, New Zealand, Nigeria, Pakistan, South Korea, Yugoslavia and Taiwan. G22 locomotives were first built in 1967 with export markets in mind, so they carried a low weight per axle. The CU version has a C-C traction motor arrangement and suits one-metre gauge, with an EMD 12-645 main engine. They were produced at the General Motors plants at La Grange and London, Canada, and under licence in other countries including Argentina and Spain. In 1972 Ferrocarriles Argentinos bought 250 locomotives including G22 and GT22 models, 96 of them the metre gauge CU version for the Belgrano line, and many still run in 2015.
