South African type JT1 tender

Type JT1 tenders were built between 1947 and 1953 by the South African Railways (SAR) and North British Locomotive Company (NBL).^[1][2]

In 1947 and 1948, the SAR built and placed twelve Class S1 eight-coupled shunting steam locomotives in service. The engines and tenders were built by the Salt River shops in Cape Town to the design of Dr. M.M. Loubser, Chief Mechanical Engineer (CME) of the SAR from 1939 to 1949, and were initially placed in service in the yards in Cape Town. A further 25 Class S1 locomotives were subsequently ordered from NBL in Glasgow, built in 1953 and delivered in 1953 and 1954. The Type JT1 entered service as tenders to these locomotives.^[1][2][3]

The tender was arranged for manual stoking and had a coal capacity of 11 long tons (11.2 tonnes) and a water capacity of 6,000 imperial gallons (27,300 litres). As on the Type GT tender of the Class S shunting locomotive, the top sides of its coal bunker were set inwards to improve the crew's rearward vision. The front of the engine and the back of the tender were fitted with modified and strengthened draft gear and both were fitted with vacuum brakes. It was built with an underframe and bogies identical to those of the Type JT tender.^{[1][2][3][4][5]}
