The . CYI No. 22 was a zweigekuppelte, loose wheelset narrow gauge - Tenderlokomotive the Kleinbahnen the circle Jerichow I (CYI).
history
Due to a lack of locomotives, the KJI took over a construction locomotive from the Polensky & Zöllner company that was already in use on its route network during the construction of the Magdeburg – Berlin motorway . The machine of the Henschel factory locomotive type bamms was built by the Henschel factory in 1922 with the serial number 19.514. After adapting it to normal rail operations on public railways in the KJI workshop, it was used in shunting and now and then as a locomotive for the railway's auxiliary train. During her time with the KJI, the locomotive was stationed in Burg .
At the Deutsche Reichsbahn it was given the number 99 4401 in 1949, it was not until 1956 that it was given the correct number 99 4721 for a locomotive with a seven-ton axle load. After the KJI was closed in 1966, it was still used to dismantle the tracks and finally in the same year on the "Young Technician Club" sold in Halberstadt.
technical features
The locomotive had an inner frame in which a frame water tank was integrated. The external two-cylinder wet steam engine with simple steam expansion drove the second wheel set as a drive wheel set. The steam engine of the locomotive was controlled by an Allan trick control and had flat slide and a two-rail guide for the crosshead. In addition to the frame water tank, further water tanks were arranged on the left and right of the boiler, and the coal supplies of the machine were stored on the left tank. The locomotive did not have a train brake, only a handbrake acting on the drive wheel set.
