In 1911, the Lüderitzbucht Eisenbahn (Lüderitzbucht Railway) in German South West Africa placed two tank locomotives with a 0-6-0 wheel arrangement in service as shunting engines. They were apparently no longer in service when all railways in the territory came under the administration of the South African Railways in 1922.[1]

Manufacturer

During 1911, two Cape Gauge tank locomotives with a 0-6-0 wheel arrangement were delivered to the Lüderitzbucht Eisenbahn by Orenstein & Koppel. The locomotives, with works numbers 4256 and 4257, were supplied in January 1911 to the order of Consortium Bachstein-Koppel. They were numbered 201 and 202 and were placed in service as shunting engines.[1][2]

Characteristics

The locomotive's coal bunker had a capacity of 1 long ton (1.0 tonne) and the side-tanks had a water capacity of 484 imperial gallons (2,200 litres). It had coupled wheels of 31 ¹⁄₂ inches (800 millimetres) diameter and cylinders of 13 inches (330 millimetres) bore and 15 ³⁄₄ in (400 mm) stroke. The total weight of the engine in full working order was 22 long tons (22,350 kilograms) and it had a tractive effort of 8,660 pounds-force (38.5 kilonewtons) at 75% of boiler pressure.[1]

Service

The two engines were placed in shunting service in Lüderitz. It is not known whether they survived the First World War and they do not appear to have still been in service on 1 April 1922, when all railways in the former German colony came under the administration of the South African Railways.[1]
