The GE U26C diesel locomotive model was introduced by GE Transportation Systems in 1971. All examples of this model are six axle units, and have the wheel arrangement C-C (AAR classification) or Co'Co' (UIC classification).
The U26C locomotives were built for 1,000 mm (3 ft 3 3⁄8 in) metre gauge networks in Brazil and Kenya, and 3 ft 6 in (1,067 mm) networks in New Zealand and South Africa. All had a power output of 2,050 kW (2,750 hp) as built, except the locomotives delivered new to Kenya, which were derated to 1,950 kW (2,610 hp). Some of the New Zealand units were later uprated in power output, and four of the Brazilian units were later regauged to 1,600 mm (5 ft 3 in) broad gauge.
Another more powerful version, license-built by Krupp, and referred to as a GE U30C model, was delivered to the 3 ft 6 in (1,067 mm) TAZARA Railway, which links Tanzania with Zambia.
The U26Cs have the typical hood unit configuration of North American diesel locomotives, and a road switcher design.
The turbocharged V12 four-stroke diesel engine, generator and auxiliary equipment are easily accessible under a long hood equally as high as, but narrower than, the single cab, which is mounted at one end. This arrangement allows the driver to see in both directions. However, in line service the leading locomotive is usually operated with the cab end ahead.
