Data from DeGolyer, Volume 79, pp. 546+; see also the Brecon Mountain Railway site at [], last accessed 10 October 2013; and Bill Hogan, Uloliwe Volume 3, No 11 Baldwin works number was 61269 in March 1930.
The EPCC was a wholly owned subsidiary of the Pretoria Portland Cement Company that opened in 1927. It operated a very narrow gauge railway between the factory at New Brighton in Port Elizabeth and the junction with the Avontuur Railway at Chelsea Junction. Clearly the locomotive buyer for the EPCC was familiar with the South African Railways' NG10 class that had come from Eddystone in 1916 (Locobase 986) and thought it suitable for the EPCC. So the company ordered a duplicate sixteen years later.
It was obviously satisfactory for it was still in service in 1974 when it ran away and wrecked. The UK's Brecon Mountain Railway believed it could restore the locomotive and bought it after the insurance company wrote it off. Restoration, which began in 1990, was "extensive as the loco had suffered severe damage in the accident" according to the BMR's history, but the engine entered museum service in 1997 as an oil-burner. Ten years later the 2 was converted back to coal burning.
