. Both these manufacturers also produced locomotives for the South African Classes 33, 35 and 36.

Distinguishing Features

As built, the GE Class 34-000, 34-400 and 34-900 locomotives were visually indistinguishable from each other. The Class 34-500 locomotives could be visually distinguished from the other series by the air conditioning units mounted on their cab roofs and initially, when it was still a feature unique to them, by their running board mounted handrails. At some stage during the mid 1980s all Class 34-000, 34-400 and 34-500 locomotives had saddle filters installed across the long hood, mounted just to the rear of the screens behind the cab on the sides. Since then Class 34-900 locomotives could be distinguished from the older models by the absence of the saddle filter.

South African Railways

GE Class 34-400s work on most mainlines and some branchlines in the central, western, southern and southeastern parts of the country. Some eventually joined the Class 34-500 on the 861 kilometres (535 mi) Sishen-Saldanha iron ore line to haul export ore from the open cast iron mines at Sishen near Kathu in the Northern Cape

Running board mounted handrails

Class 34-400 locomotives that are allocated to the Sishen-Saldanha Orex line are often modified by having removable running board mounted handrails installed. All South African diesel-electric locomotives have their side handrails mounted along the upper edges of their long hoods. The ex Iscor Class 34-500s, however, came equipped with additional removable running board mounted handrails. Since these handrails are slide-fit into brackets welded onto the running board, they are easily removed.

Since circa 2009 other mainline diesel-electric locomotive types also emerged from the Koedoespoort Transwerk shops with running board mounted handrails after major overhauls.

Fuel capacity

The Class 34-400 has a 5400 litre fuel tank as built, while the Class 34-500 was delivered new to Iscor with a 7000 litre fuel tank in order to cope with the longer distance between refuelling points on the Sishen-Saldanha Orex line. To facilitate the larger fuel tank, the inter-bogie linkage found on all other models was omitted on the Class 34-500.

In order to be usable on the iron ore line, Class 34-400s that end up working there are modified to a similar capacity. The inter-bogie linkage is removed and the fuel tank is enlarged by changing it from saddle shaped to rectangular shaped, as illustrated by the welds on the end of 34-080’s fuel tank in the picture alongside.

Leased and sold

Eleven Class 34-400s were leased to the Kenya Railways for some years, regauged to gauge and numbered 9501 to 9511. They were returned to Spoornet in April 2002.

Several Class 34-400s were sold into industry. 34-429 went to the Douglas Colliery near Witbank as D10. Five went to Sasol

 diesel-electric locomotives. In South Africa mixed electric and diesel-electric consists are unique to the iron ore line.

A Class 9E or Class 15E electric locomotive serves as the master of each mixed electric and diesel-electric consist, with a total of between nine and twelve locomotives per train, twelve being the maximum number allowed. Before the Class 15E was placed in service in 2010, motive power usually consisted of three sets of locomotives, each set made up of one or two Class 9E electrics and one or two Class 34 diesel-electrics, with each set’s leading electric locomotive controlling its respective set of diesels by means of a slimkabel (smart cable). In effect each ore train was made up of three separate 114 wagon trains consisted together, with the locomotives of all three trains controlled by means of a Locotrol

 radio distributed power control system by one crew in the leading electric locomotive. A typical train would therefore be made up of locomotive set A, 114 wagons, locomotive set B, 114 wagons, locomotive set C, and 114 wagons.

Some problems were experienced using this configuration, and after a couple of major derailments the locomotive configuration was changed to four sets, with locomotive set D initially made up of two Class 34 diesel-electric locomotives at the rear end of the train, pushing at between 40% and 50% of tractive power at all times, depending on the grades being traversed. The total maximum number allowed was still between nine and twelve locomotives per train.

As more Class 15Es were delivered and placed in service, Class 9E or 15E electrics replaced the pair of Class 34 diesel-electrics in set D. At the same time the more powerful Class 15E also made it possible to use as few as seven locomotives per train, with locomotive sets A, B and C each made up of one Class 15E and one Class 34, and set D of a single Class 15E.

Liveries and modifications

The main picture shows 34-401 in Spoornet blue livery with outline numbers. Since 2010 some locomotives are being equipped with electronic fuel injection and GE Brite Star control systems. Evidence of this modification is the raised portion of the long hood, visible in the photograph of 34-418 below.
