South African Class 7E 4-8-0

The South African Railways Class 7E 4-8-0 of 1899 was a steam locomotive from the pre-Union era in the Cape of Good Hope.

In 1899, the New Cape Central Railway placed one Cape 7th Class 4-8-0 Mastodon type steam locomotive in service. Another three were commissioned in 1900, two more in 1903 and another one in 1904. In 1925, when the New Cape Central Railway was amalgamated into the South African Railways, these seven locomotives were renumbered and designated Class 7E.^[1][2][3]

New Cape Central Railway

The New Cape Central Railway (NCCR) was formed in January 1893, when it purchased all the assets of the bankrupted Cape Central Railway (CCR), who had constructed a railway line from

The tracks were originally laid with 46+1⁄2 pounds per yard (23.1 kilograms per metre) rail. When Voorbaai near Mosselbaai was reached in 1904, 211 miles (340 kilometres) from Worcester, it made the NCCR the longest private railway in South Africa.^[1][2][4]

Manufacturers

The original Cape 7th Class locomotive had been designed in 1892 by H.M. Beatty, at the time the Cape Government Railways Western System Locomotive Superintendent. The NCCR acquired its first seven Cape 7th Class locomotives piecemeal over a period of five years. The first locomotive, NCCR no. 1, was ordered from Neilson, Reid and Company in 1899, followed by three more from the same manufacturer in 1900, numbered in the range from 2 to 4.^[1][2][3][5]

Two more were ordered from Neilson, Reid in 1903, numbered 5 and 6, but since three Scottish locomotive builders (Dübs and Company, Neilson, Reid and Sharp, Stewart and Company) merged into the North British Locomotive Company (NBL) while the locomotives were being built, they were delivered as having been built by the newly established NBL at the Hyde Park works of the former Neilson, Reid.^{[1][2][3][6][7]}

The seventh 7th Class locomotive, no. 7, was acquired in 1904, also built by NBL. On the NBL works list, this locomotive is shown as actually having been built for Pauling and Company, the contractors who constructed the railway.^{[1][2][3][6][7]}

Class 7 sub-classes

In 1925, the NCCR was amalgamated into the South African Railways (SAR) and these seven 7th Class locomotives were taken onto the SAR roster, designated Class 7E and renumbered in the range from 1344 to 1350.^[1][3]

Other 7th Class locomotives which had come onto the SAR roster from the Colonial railways in the Southern African region in 1912, namely the

During the 1930s, many of the Class 7 family of locomotives were equipped with superheating and piston valves. On the Class 7B and Class 7C, this conversion was sometimes indicated with an "S" suffix to the class letter on the locomotive number plates, but on the rest of the Class 7 family this distinction was not applied consistently. The superheated versions could be identified by the position of the chimney on the smokebox, the chimney having been displaced forward to provide space behind it in the smokebox for the superheater header.^[3][8]

Service

In SAR service, the Class 7 family served on every system in the country. They remained in branch line service, particularly at Tarkastad and Ladysmith and also on the Touws River-Ladismith branchline, where three Classes 7 and 7A and one Class 7E were on strength in January 1956.^[3][9][10]

By April 1962, two Class 7Es, numbers 1347 and 1348, were still shedded at Touws River to work the Ladismith branch. The Class 7Es were long-lived and these last two engines of the class were withdrawn from service in 1965.^[10]
