The '''South African Railways Class {{nowrap|35-600}}''' of 1976 is a branch line diesel-electric locomotive.
Between September 1976 and June 1978, the South African Railways placed one hundred Class {{nowrap|35-600}} General Motors Electro-Motive Division type GT18MC diesel-electric locomotives in branch line service. In 1977, one more Class {{nowrap|35-600}} locomotive was built for Columbus Stainless in Middelburg, Transvaal.<ref name="Middleton">{{Middleton-SA Loco Guide|pages=38, 42-43, 46}}</ref><ref name="E&D diagram-book">South African Railways Index and Diagrams Electric and Diesel Locomotives, 610mm and 1065mm Gauges, Ref LXD 14/1/100/20, 28 January 1975, as amended</ref>
== Manufacturer == The Class {{nowrap|35-600}} type GT18MC diesel-electric locomotive was designed by [[Electro-Motive Diesel|General Motors Electro-Motive Division]] (GM-EMD) and built in two batches for the South African Railways (SAR) by [[General Motors South Africa]] (GMSA) in [[Port Elizabeth]]. Fifty were delivered between September 1976 and May 1977, numbered in the range from {{nowrap|35-601}} to {{nowrap|35-650}}, and another fifty between May 1977 and June 1978, numbered in the range from {{nowrap|35-651}} to {{nowrap|35-700}}.<ref name="Middleton"/><ref name="E&D diagram-book"/><ref name="Paxton-Bourne">{{Paxton-Bourne|pages=141–142}}</ref><ref name="EMD Exports">[http://emdexport.railfan.net/africa/safrica7.html EMD Exports – South African Railways GT18MC]</ref>
In addition, another single Class {{nowrap|35-600}} GT18MC locomotive was built new in 1977 for [[Middelburg, Mpumalanga#Economy|Columbus Stainless]], a large [[stainless steel]] plant which was established in [[Middelburg, Mpumalanga|Middelburg]], Transvaal in 1965.<ref name="Middleton"/>
== Distinguishing features == Of the GM-EMD Class 35 locomotives, the Class {{nowrap|35-200}} and {{nowrap|35-600}} are visually indistinguishable from each other.<ref name="E&D diagram-book"/>
== Service == The Class 35 family is South Africa's standard branch line diesel-electric locomotive. The GM-EMD Class {{nowrap|35-600s}} were designed for light rail conditions and they work on most branch lines in the central, eastern, northern and northeastern parts of the country.<ref name="Paxton-Bourne"/> A number of them also saw service in Richards Bay working the Golela line.

== Liveries == The Class 35-600 were all delivered in the SAR Gulf Red livery with signal red buffer beams, yellow side stripes on the long hood sides and a yellow V on each end. In the 1990s many of them began to be repainted in the Spoornet orange livery with a yellow and blue chevron pattern on the buffer beams. Several later received the Spoornet maroon livery. In the late 1990s many were repainted in the Spoornet blue livery with outline numbers on the long hood sides. After 2008 in the [[Transnet Freight Rail]] (TFR) and [[Passenger Rail Agency of South Africa]] (PRASA) era, many were repainted in the TFR red, green and yellow livery and at least one was repainted in the PRASA blue livery.<ref name="Middleton"/><ref name="Soul of a Railway 7-9">[https://sites.google.com/site/soulorailway/home/system-7-1/south-eastwards-as-far-as-volksrust-2nd-section-wattles-to-union-junction-by-les-pivnic Soul of A Railway, System 7, Western Transvaal, based in Johannesburg, Part 9.
