The class 99.450 of the Deutsche Reichsbahn grouped three-axle locomotives of the former small railways in the West and East Prignitz districts.
99 4501-4503
They originally wore the numbers 14-17. They were built in 1897 and 1900 by the Saxon machine works Hartmann . The vehicles were used on the routes from Kyritz via Hoppenrade to Breddin and from Viesecke and Glöwen . Locomotive 15 went to the Soviet Union in 1945 as a reparation payment . After the three remaining locomotives were taken over by the Deutsche Reichsbahn on April 1, 1949 , they were used as replacement vehicles on various railways with the road numbers 99 4501–99 4503. In 1964 and 1966 the 99 4501 and 99 4502 were taken out of service, the 99 4503 was reconstructed in 1965 in the RAW Görlitz, it received new buffer carriers and a new boiler. Despite this rejuvenation, it was shut down in 1968 and then sold to a Berlin train driver. It was not able to operate and is now in the Brandenburg Museum for Small and Private Railways in Gramzow / Uckermark .
