Holland's Iron Railway Company type 2
In 1866, Borsig of Berlin supplied ten 2-4-0 passenger locomotives to the Hollandsche IJzeren Spoorweg-Maatschappij or Holland Railway company. They were numbered 16 to 25 and named after provinces of the Netherlands, starting with “Groningen” and ending with “Limburg”. The company designated them “type 2”, while the 20 locomotives of the same basic dimensions delivered by Stephenson in 1866 and 1867 became „type 1”. The Borsig locomotives had horizontally mounted outside cylinders and Allan valve gear. Driver diameter was 1,860 mm (6 ft 1 in) and the cylinders measured 406 by 558 mm (16 by 22 inches) The footplate only had low walls and a roof.
In 1870, Borsig delivered four more locomotives which were numbered 36 to 39. These were named “Europa”, “Azia”, “Afrika” and “Amerika”. They had Stephenson valve gear and were the first locomotives of the company which had steam injectors instead of crosshead feed water pumps. On the outside, the only difference was the changed shape of the chimney. Later rebuilds of the locomotives featured a cast chimney, a closed cab and a Westinghouse air brake. They were withdrawn between 1902 and 1917.
