The **South African Railways Class 3E** of 1947 was an electric locomotive.

In 1947 and 1948, the South African Railways placed twenty-eight **Class 3E** electric locomotives with a Co+Co wheel arrangement in mainline service.[1]

## Manufacturer

The South African Railways (SAR) placed orders for the design and construction of the 3 kV DC Class 3E electric locomotive with [Metropolitan-Vickers](/source/Metropolitan-Vickers) (Metrovick) in 1944. Although the locomotive was designed by Metrovick who also supplied the electrical equipment, its construction was subcontracted to [Robert Stephenson and Hawthorns](/source/Robert_Stephenson_and_Hawthorns). Twenty-eight locomotives were delivered and placed in service in 1947 and 1948, numbered in the range from E191 to E218.[1][2]

## Characteristics

These dual cab locomotives have three windows between the side doors on one side and four on the opposite side. When the locomotive is observed from the side with three windows, its no. 1 end will be to the viewer's left. As on the later [Class 4E](/source/South_African_Class_4E), the locomotive had side doors on both sides behind each cab.[3]

[Builder's plate](/source/Builder's_plate)

Like the [Classes 1E](/source/South_African_Class_1E), [2E](/source/South_African_Class_2E) and 4E, the Class 3E had bogie-mounted [draft gear](/source/Draft_gear), therefore no train forces were transmitted to the locomotive body. It had a [Co+Co](/source/Co%2BCo) wheel arrangement with an articulated inter-bogie linkage.[3]

For the passenger role, provision was made for both electric and steam heating of passenger coaches, although the electric heating feature was never used on mainline passenger trains. The Class 3E had an on-board steam-heating boiler for train heating and were the only electric units to have this feature. Subsequent electric locomotive models like the Classes 4E, 5E and 6E used separate steam wagons on passenger service during the winter months.[1][4]

Class 3E on the Pretoria-Johannesburg express commuter

Unlike Cape Town's and Durban's suburban trainsets, those working around Johannesburg had jumper connections on the roof above the end connecting doors. The Class 3Es were also equipped with these connections, immediately to the right hand side of each headlight. During a shortage of suburban motor coaches c. 1948–1949, Class 3Es were used to haul suburban sets on the Witwatersrand and it is likely that the electric heating system was used during those winters. In the picture alongside showing rarely seen snow on the ground along the [Johannesburg](/source/Johannesburg)-[Pretoria](/source/Pretoria) line on the Transvaal Highveld, the roof jumper connections between the suburban coaches and next to the unit's headlight are visible.

The locomotives entered service in an all-green livery which was changed to green with yellow whiskers in the 1950s and to gulf red with yellow whiskers in the 1960s.[5]

## Service

The Class 3E was the first six-axle electric locomotive in SAR service and was geared for a maximum safe speed of 105 kilometres per hour (65 miles per hour). It was designed for both goods and passenger working on the Western Transvaal System, where higher speeds were possible on track with less severe curvature than on the lower Natal mainline. Some did enter service in Natal in 1948, but since they were not really suitable for Natal's tight and constant curvature, some difficulty was experienced with cracked frames and these units were soon also transferred to Johannesburg. The whole class was based at the Electric Running Shed at [Braamfontein](/source/Braamfontein), where they remained for the rest of their service lives.[1][6]

The Class 3E was a versatile locomotive, equally at home on heavy goods trains or hauling the Blue Train at its maximum speed. Since it was a powerful locomotive, it invariably worked as single unit and double-heading was rare. In 1951, after the Cape mainline west of Johannesburg was electrified from [Randfontein](/source/Randfontein) via Bank as far as Welverdiend 60 miles (97 kilometres) from Johannesburg, Class 3E locomotives were assigned to work top-link south-bound passenger trains to that station, from where a [Klerksdorp](/source/Klerksdorp)-based [Class 23](/source/South_African_Class_23_4-8-2) would take over. This was part of the scheme to eliminate steam traction out of the new Johannesburg station. All surviving 3E's were staged at Braamfontein in c. 1983-84 and scrapped, with the exception of no. E201.[4][7][8][9]

## Preservation

No. E201, the only survivor of the Class, was stored for several years under a shelter at the [Bellville](/source/Bellville%2C_South_Africa) locomotive depot in [Cape Town](/source/Cape_Town) along with a few other early SAR electric and diesel-electric locomotives which were earmarked for preservation.[2] During 2015, most of these locomotives were relocated to Bloemfontein, including the Class 3E.
