South African Class 32-000
No. 32-029 and 32-042 at Oudtshoorn,
22 September 2007
The South African Railways Class 32-000 of 1959 was a diesel-electric locomotive.
Between November 1959 and November 1961, the South African Railways placed 115 Class 32-000 General Electric type U18C1 diesel-electric locomotives with a 1Co+Co1 wheel arrangement in service in South West Africa.
The South African Class 32-000 type GE U18C1 diesel-electric locomotive was designed and built to South African Railways (SAR) requirements by General Electric (GE) and imported. They were numbered in the range from 32-001 to 32-115.
Class 32 series
The Class 32 consisted of two series, the high short hood Class 32-000 and the low short hood Class 32-200, both GE products and both with a 1Co+Co1 wheel arrangement. The short hood end was the front on both versions and both had single station controls.
The pony truck affair
In the United States of America, the South African Class 32-000 is credited with being a major factor in the demise of the American Locomotive Company (ALCO) and the rise of GE in the locomotive building business.
In the late 1950s South Africa, at the time one of the last bastions of steam traction, planned to embark on a massive dieselisation program. A SAR technical team was sent to Europe and the United States to prepare an assessment of design alternatives, finalise specifications and compile a list of qualified bidders.
In the United States only ALCO, GE and General Motors Electro-Motive Division (EMD) were considered to be qualified bidders. The SAR was not very enthusiastic about two-stroke cycle prime movers and had a strong preference for ALCO's Model 251 prime mover and GE's transmission systems. As a long-time prior supplier of steam locomotives for the SAR, ALCO appeared to be virtually assured of receiving the order.
The SAR's tender for bid was issued in 1957, with two options:
- 115 1,800 horsepower (1,300 kilowatts) locomotives with a 1Co+Co1 wheel arrangement; or
- 230 1,000 horsepower (750 kilowatts) locomotives with a Co+Co wheel arrangement
These units were intended for operation in South West Africa (SWA) under very light rail conditions that necessitated lighter axle loadings which could not be achieved with conventional Co bogies under a heavy locomotive. General Steel Castings had a design on paper for a 1Co bogie, a Co bogie with an integral pony truck, which could be utilised by either ALCO or GE and which would enable the SAR's specifications to be met for the heavier 1,800 horsepower (1,300 kilowatts) units.
The SAR made it clear that, despite the two options afforded by the tender, its strong preference was for a 1Co+Co1 locomotive. The use of a pony truck was not universally accepted by ALCO's engineering management, however, and the result was that ALCO bid on only the Co+Co option and lost out to GE, who had bid on both options.
South African Railways
Some initially entered service at Germiston to work coal trains on the Witbank coal line where electrification was approaching completion. From Germiston they worked all sorts of traffic, including the Trans-Natal Express between Johannesburg and Volksrust. Ten of these units were temporarily allocated to De Aar in the last quarter of 1961 to work the mainline to Beaufort West. Between 1964 and 1976, several were also allocated to the Eastern Transvaal for service around Waterval Boven.
Of the original 115 locomotives, only five survived into the Spoornet era in the 1990s. In SWA they began to be replaced by the Class 33-400 during the early 1970s. After being withdrawn from Spoornet service, a few were allocated to the National Collection, later the Transnet Heritage Foundation, and two of these, numbers 32-029 and 32-042, still saw occasional service as Outeniqua Choo-Tjoe excursion locomotives based at George, Western Cape. Numbers 32-021 and 32-094 were staged at Danskraal for years and were sold in 2013, believed to be for further use by the buyer.
After withdrawal from SAR service in the 1980s, almost fifty of the Class 32-000 locomotives were sold to Zaire's Société Nationale des Chemins de Fer Zaïrois (SNCZ) which became the Société nationale des Chemins de fer du Congo (SNCC) after the country's name change to the Democratic Republic of the Congo. Of these at least one, SNCC no. 1405 (ex SAR no. 32-019) was seen on local workings around Lubumbashi in 2013.
Numbers 32-007, 32-010, 32-013, 32-069 and 32-113 went to Zambia, two to Nchanga and three to Nkana, two of the Zambian copper mines, where they were used on the mine systems at Nchanga and Kitwe on both ore trains and miner's passenger trains. The three locomotives at the Nkana Mine retained their SAR numbers. No. 32-013 is depicted alongside on the Nkana-Chibuluma miner's train at Nkana Mine Sidings in Zambia. The coaches behind it are second-hand Tata bus bodies mounted on freight wagon frames and bogies which were initially made for the Mulungushi Commuter train service in Lusaka, which was later taken over by Zambia Railways and renamed Njanji Commuter.
LEGE in Durban, who operates an active hire and overhaul business, owns two of these locomotives, numbers 32-070 and 32-084. Of these, no. 32-070 has been observed shunting in the Merewent Oil Refinery on the Bluff as late as 2014.
The class 32-000 were delivered in the new Gulf Red livery with yellow side-stripes and a yellow V on each end. They wore this livery throughout their SAR and Spoornet service life.
The Class 32-000 builder's works numbers and known disposition are listed in the table.
