B22 (indonesian Steam Loco)

In addition to rich natural resources, such as teak, the northern coast of Central Java and East Java, there are also oil and gas, both in Cepu (Central Java) and in Bojonegoro (East Java). To support the acceleration of trade flows of agricultural and industrial estates and the railway was built. After the private railway company Spoorweg Nederlands-Indische Maatschappij (NIS) managed to build a railway route Semarang - Gundih - Solo - Yogyakarta (166 km) in the year 1867 to 1872, the NIS and the continuing development of the railway route Surabaya Pasar Turi - Tripe ( 69 km) was completed in 1900, the route Tripe - Bojonegoro - Cepu (72 km) was completed in 1903 and the route Gundih - Gambringan - Cepu (89 km) was completed in 1902. This railway line has become an important trade route, the valley Bengawa Solo is located in the northern part of East Java. NIS bring steam locomotives from the factory B22 Hartmann (Germany) as much as 20 locomotives in the year 1989 to 1901. This locomotive used to pull the train transporting crops, plantation crops, minerals or passengers.After World War II ended, 1 B22 locomotives moved from Java to South Sumatra and the rest scattered in Solo, Gundih, Kudus and Purwodadi.This locomotive has two drive wheels (wheel arrangement-2T 0-4) with two-cylinder compound. On a steam locomotive with a two-cylinder compound, high pressure steam supplied from cylinder to cylinder low pressure greater volume of high pressure cylinders (so steam can develop further expand and generate more propulsion). The new low-pressure steam from the cylinder which is already in use discharged through the chimney. Although the two-cylinder steam locomotive compound can provide higher efficiency, but the treatment is more complicated. After the discovery of the type of locomotive steam superheater like this is never made again.B22 locomotive has a length of 7850 mm and weighs 25.1 tons. B22 locomotive can be sped up to speeds of 55 km / h. This locomotive fuel use teak wood or coal.Of the 20 locomotives B22, the current remaining 3 pieces of the B2207, B2209 and B2220. B2207 (began operations in 1898) in Cibubur Camping (Jakarta), B2209 (began operations in 1898) on display at the Museum of Transport Taman Mini Indonesia Indah (Jakarta) and B2220 (began operations in 1900) on display at the Museum Ambarawa KA (Central Java) .
