The South African Railways Class 2E of 1937 is an electric locomotive.
In 1937 the South African Railways placed three German-built Class 2E 3 kV DC electric locomotives with a Bo+Bo wheel arrangement in mainline service.[1]
Manufacturer
South Africa's second mainline electric locomotive type, the Class 2E, entered service in Natal in 1937, intended for mixed traffic haulage. The electrical equipment was designed by Siemens-Schuckert and the three locomotives were built for the South African Railways (SAR) by Henschel and Son in Germany. Numbered in the range from E134 to E136, they were the only German-built electric locomotives ever supplied to South Africa.[2][3]
The Class 2E was very similar in external appearance and dimensions to the Class 1E, the main visual distinction being the difference in window and grille layout on the locomotive sides. The internal arrangement of their electrical components differed from those of the Class 1E and their four 402 horsepower (300 kilowatts) traction motors made them more powerful. Even so, only these three were ever acquired, after which the SAR reverted to the Class 1E, Series 5 to 7, for its subsequent acquisitions of similar electric locomotives.[2]
Orientation
These dual cab locomotives had three windows with a grille between each pair of windows on one side, and a line of five grilles and two windows on the other side. When observing the locomotive from the side with the five grilles, the number 1 end of the locomotive would be to the left.[1]
The Class 2E had a Bo+Bo wheel arrangement with an articulated inter-bogie linkage. Like the Classes 1E, 3E and 4E, it had bogie mounted draft gear, therefore no train forces were transmitted to the locomotive body.[1]
Service
The three Class 2E locomotives spent most of their years in service on the mainline between Transvaal and Natal and only briefly served in the Western Cape, near the end of their service lives. They were withdrawn from service in 1973.[2]
