Allanridge is a Gold Mining Town in the Lejweleputswa District Municipality of the Free State province in South Africa, 34 km North of Welkom. It was founded in 1950 and administered by a village management board. Named after Allan Roberts, who was one of the prospectors in the Orange Free State. Refering to the image of the train-coach; this 4-8-2T locomotive, supplied new to Loraine Gold Mine as No 1, was built in 1951 as works no 27090 according to the standard NBL 20" x 24" design. Somewhere during its History it also picked up plates from NBL 27404, which served as No 2 at the mine. By 1991 No 1 was plinthed outside the Mine Offices.
