In 1902 the Natal Government Railways placed ten 4-6-4T tank steam locomotives in service. In 1912, when these locomotives were assimilated into the South African Railways, they were renumbered and classified as Class E.[1][2]
Manufacturer
The last locomotive to be designed for the Natal Government Railways (NGR) by Locomotive Superintendent G.W. Reid before he relinquished his appointment in 1902 was a 4-6-4T tank locomotive. It was built for the NGR by Neilson, Reid and Company, who delivered ten of them in 1902, numbered 1 to 10. In NGR service they were known as the "Neilson Reid" locomotives.[1][4]
The Neilson Reid class was a larger version of the rebuilt NGR Class K&S 4-6-4T locomotive that later became the Class C2 on the South African Railways (SAR), and many of the main dimensions were identical. They had plate frames, Stephenson valve gear and used saturated steam.[1][4]
South African Railways
When the three colonial railroads were amalgamated into the South African Railways (SAR) in 1912, these locomotives became the SAR’s Class E and were renumbered 87 to 96.[2][3][4]
Service
The locomotives were built specifically for use on the Natal South Coast and the Richmond branch. In SAR service the Class E was mainly used for shunting. They were later transferred to the Cape Midlands, where they remained until they were withdrawn from service in 1937.[4]
