In 1937 the South African Railways placed three German built Class 2E 3 kV DC electric locomotives with a Bo+Bo wheel arrangement in service.[2]

South Africa's second 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 E134 to E136, they were the only German built electric locomotives ever supplied to South Africa.[3]
The Class 2E was similar in external appearance 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 that 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.[3]
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. The number 1 end would be at the front when the side with five grilles was to the left.[2]
Like the Class 1E, Class 3E and Class 4E, the Class 2E had bogie mounted draft gear, therefore no train forces were transmitted to the locomotive body. It had a Bo+Bo wheel arrangement with an articulated inter-bogie linkage.[2]
The three Class 2E locomotives served between the Transvaal and Natal, and briefly in the Western Cape near the end of their service lives, before being withdrawn from service in 1973.[3]
The main picture shows a Class 2E, with its right side visible, running consisted to a Class 1E.
