The HK 94-100 are four-axle Mallet locomotives with a 1000 mm gauge .

history

In 1918, the Maschinenbau-Gesellschaft Karlsruhe built seven Mallet locomotives for use on army-operated railways, as the locomotives that had already been confiscated were insufficient. For the sake of speed, older designs were used. The locomotives were approved by the Heeresprüfkommission für Feldbahnen (HK) and designated as HK 94 to 100. However, due to the end of the war, the locomotives were no longer used and were sold to various private railways, sometimes as a replacement for locomotives confiscated during the war. The HK 94 and 95 came to the Kleinbahn Haspe-Voerde-Breckerfeld (HVB), of which the HK 95 changed to Euskirchener Kreisbahnen (EKB) in 1921/1922 , the HK 96 to the Nordhausen-Wernigeroder Eisenbahn-Gesellschaft (NWE), the HK 97 bis 99 went to the AG Ruhr-Lippe-Eisenbahnen (RLE) and the HK 100 to the Albtalbahn . All but two of them were retired in the late 1950s and early 1960s.

Preserved locomotives

SEG G 2 × 2/2 105 in Blonay

The locomotive 28 of the Kleinbahn Haspe-Voerde-Breckerfeld (HVB) from Haspe was sold to the Süddeutsche Eisenbahn-Gesellschaft (SEG) for the Zell im Wiesental – Todtnau line in 1928 after the railway was switched to electrical operation and was given the number 105. From there it was transferred to the Blonay – Chamby (BC) museum railway in Switzerland in 1968 , where it was operational in the early years of the museum railway and then again from 1998.

In 1920 the Nordhausen-Wernigeroder Railway Company procured the new 41 II to supplement the Mallet locomotives 11 to 22 . It was given number 99 5906 from the Deutsche Reichsbahn (DR) . Outwardly, the locomotive is very similar to the other mallet machines, but the other driver's cab is noticeable. The locomotive is operational and is mostly used by the Harz narrow-gauge railways on the Selketalbahn in front of scheduled trains.

construction

The rear engine with the high-pressure cylinders is firmly mounted in the sheet metal frame. The front engine with the low-pressure cylinders is connected to the rear engine with a kingpin, the riveted boiler rests on it with sliding plates. Lateral leaf springs keep the engine in a central position. Both engines have an inner frame.

The steam is first directed to the rear cylinders, from where it is fed into the front cylinders via flexible lines. All cylinders have flat slide and external Heusinger control with hanging iron.

The locomotives have a throw lever handbrake and a vapor barrier as an additional brake. Depending on the railway, suction or compressed air brakes were later retrofitted as train brakes.

There are two sand domes on the boiler, one for each engine.
