The Lenz-type meters were two-axle narrow gauge - steam engines , among other things, on the Ruegen Kleinbahnen and Demminer Kleinbahn-West were in use. With the Deutsche Reichsbahn they were classified as class 99.460 .

history

The operating company Lenz & Co procured locomotives as uniformly as possible for the railways it oversees in order to save costs in purchasing and maintenance. These locomotives were identified by a letter attached to the number. "M" were locomotives with 750 mm track width and 6 t axle pressure. 40 locomotives based on a uniform template were built by Vulcan between 1896 and 1902 . They were used on various railways: Rügensche Kleinbahn (two locomotives), Demminer Kleinbahn-Ost (five locomotives), Kleinbahngesellschaft Greifswald – Jarmen (four locomotives), Stolper Kreisbahn (four locomotives), Insterburger Kleinbahnen , Bleckeder Kreisbahn (five locomotives) and other.

The small railroad department of the Provincial Association of Pomerania ordered similar locomotives from 1910, this time from Henschel . They were in use at Demminer Kleinbahn-West (three locomotives), one of which came to Rügen Kleinbahnen in 1932.

Many locomotives went to the USSR as reparations , where the tracks are lost.

Only three of the vehicles were taken over by the Deutsche Reichsbahn on April 1, 1949 and were given the numbers 99 4601 (DKBO No. 2), 4602 (RüKB No. 7) and the Henschel locomotive 99 4603 (RüKB No. 9). The number 99 4601 was sold to an industrial company in Jarmen in 1954 . The other two vehicles were retired in 1965 and 1966.

technical features

The locomotives had an inner frame and they were driven by a Stephenson control. The water tank was in the frame, the charcoal boxes were arranged next to the boiler in front of the driver's cab.

Type m at the Greifswald-Wolgast small railway company

Locomotives called type m (two-axle, axle pressure 6 t) were also in use at the Greifswald-Wolgast small railway company . But they differed from the Vulcan locomotives. In 1898 three locomotives were delivered by the Hohenzollern corporation for locomotive construction, which were handed over to the Königsberger Kleinbahn at the end of 1899 . A fourth locomotive delivered in 1900 was probably delivered to the Wehlau – Friedländer Kreisbahnen straight away. In return, the railway received four locomotives from the Wehlau – Friedländer Kreisbahnen, which were manufactured by the Union foundry in Königsberg in 1898 and had the rare Joy control . They also had the numbers 1 to 4. Locomotives 3 and 4 were scrapped around 1940, 1 and 2 were still given the numbers 216 and 217 of the Pomeranian State Railways and were in use until they were closed in 1945.
