The South African Class 34-200 of 1971 is a South African diesel-electric locomotive from the South African Railways era.

Between October 1971 and March 1972 the South African Railways placed fifty Class 34-200 General Motors Electro-Motive Division type GT26MC diesel-electric locomotives in service.[2]

Manufacturer[edit]

The Class 34-200 type GT26MC diesel-electric locomotive was designed and built for the South African Railways (SAR) by General Motors Electro-Motive Division (GM-EMD) and imported. Fifty locomotives were delivered between October 1971 and March 1972, numbered in the range from 34-201 to 34-250.[1][2][3]

Class 34 series[edit]

GE and GM-EMD designs[edit]

The Class 34 locomotive group consists of seven series, the General Electric (GE) Class 34-000, 34-400, 34-500 (also known as "34-400 ex Iscor") and 34-900, and the GM-EMD Class 34-200, 34-600 and 34-800. Both these manufacturers also produced locomotives for the South African Classes 33, 35 and 36.[2]

Distinguishing features[edit]

On the GM-EMD Class 34 series locomotives, Class 34-200 and 34-600 locomotives are visually indistinguishable from one another, but they can be distinguished from the Class 34-800 by the thicker fishbelly shaped sills on their left sides, compared to the straight sill on the left side of the Class 34-800.[4][5]

Service[edit]

Transnet Freight Rail[edit]

In Transnet Freight Rail (TFR) service the Class 34-200s work on most mainlines and some unelectrified branchlines in the central, eastern, northern and northeastern parts of South Africa.[3]

NLPI Ltd.[edit]

NLPI Limited (abbreviated from New Limpopo Projects Investments), a Mauritius registered company, specialises in private sector investments using the build-operate-transfer (BOT) concept. It has three connected railway operations in Zimbabwe and Zambia that form a rail link between South Africa and the Democratic Republic of Congo.[1]

In Zambia the RSZ locomotive fleet includes former ZR locomotives, but the rest of the locomotive fleet of all three operations consist of South African GM-EMD Class 34-200, 34-600 and 34-800 and GE Class 35-000 and 35-400 locomotives. These locomotives are sometimes marked or branded as either BBR or LOG or both, but their status, whether leased or loaned, is unclear since they are still on the TFR roster and still often work in South Africa as well.[1]

Sheltam[edit]

One of the Class 34-200 locomotives, no. 34-221, was sold to Sheltam where it became their number 4, since renumbered to 2601. Sheltam is a locomotive hire and repair company that undertakes complete operating contracts and maintenance contracts, based at the Douglas Colliery near Witbank in Mpumalanga. By the turn of the millennium Sheltam locomotives were operating at Randfontein Estates Gold Mine in Gauteng, and in Mpumalanga at Douglas and Vandyksdrift Collieries and at SAPPI, Ngodwana. They also operated on Spoornet’s Newcastle-Utrecht branch in KwaZulu-Natal and on Kei Rail in the Eastern Cape. Outside South Africa they operate on the BBR, NLL and RSZ lines through Zimbabwe and Zambia and in the Congo.[1][6]

Works numbers[edit]

The Class 34-200 builder’s works numbers and deployment are set out in the table.[1]

Liveries illustrated[edit]

The main picture shows the right side of no. 34-227 in the Spoornet orange livery. The left side and the NLPI LOG livery as applied to Class 34-200 locomotives are illustrated below.
