A narrow-gauge army field railway locomotive that was in use on the narrow-gauge line Eichstätt – Kinding was classified as the Bavarian Gts 2 × 3/3 .
State railway locomotive
The locomotive was built in 1917 by Henschel & Sohn in Kassel under the serial number 15160 for the Deutsche Heeresfeldbahnen . After the end of the First World War , the machine was sold to the Royal Bavarian State Railroad in 1920. It was classified as type Gts 2 × 3/3 and was given the number 996. The locomotive was used on the narrow-gauge line from Eichstätt to Kinding. During the commissioning on the Bavarian narrow-gauge line, the locomotive occasionally derailed, which could only be eliminated by improving the superstructure. After it was taken over by the Deutsche Reichsbahn , it was given the number 99 201 and was run as the 99 20 series .
The locomotive was able to meet the expectations placed on it and was preferably used in roll-head service. After its main line from Eichstätt – Kinding had been changed to standard gauge in 1934, the locomotive was parked and later scrapped.
Constructive features
In order not to exceed the permissible axle load, the locomotive was equipped with six axles, three of which were combined in one engine. Nevertheless, there was an axle load of 9 t. The compound engines were of the mallet type . The third axle was driven, the locomotives had Heusinger control with a Kuhn loop . The movably mounted front motor frame had +/- 360 mm side play at the height of the first set of wheels. The first and third axles were firmly mounted in each drive frame, the middle axle each had 15 mm side play in each direction. The steam came from the fixed high-pressure cylinders to the movable low-pressure cylinders via articulated, telescopic pipe connections and from these as exhaust steam to the chimney. All cylinders had piston valves. The boiler had Schmidt superheaters . The frames of the engines were designed as bar frames.
The boiler was supported on the front bogie between the 2nd and 3rd axles. The preheater was located behind the chimney on the top of the boiler and was along the axis. To the right and left of the preheater were the front sandboxes, the rear sandboxes, which were also divided, were to the side of the Ramsbotton safety valves.
The upper part of the driver's cab could be removed for transport purposes, the coal container sat behind the driver's cab, and the long, tapered and sloping water tanks on the side of the boiler.
The vehicle could hold 1.5 tons of coal and 4.5 cubic meters of water.
Background information on the series
Army field railway locomotives
The 99 201 was one of a total of 20 machines that Henschel delivered to the Heeresfeldbahnen from 1917 with the designation HK 11 ... HK 30 . The locomotives at Henschel had the serial numbers 15150 - 15169. Some of the machines were destroyed in the war, others remained abroad, for example in France. Some machines of this series were used on the Hejaz Railway from Damascus to Medina. One locomotive came to the Ruhr-Lippe-Kleinbahnen as 14 II . It was built in 1917 for the Heeresfeldbahn, in 1930 it was also delivered to France.
Replicas
After the First World War, Hanomag made two replicas of this series:
- In 1925, with some changes, the locomotive 104 was built for the Zell im Wiesental – Todtnau railway line of the South German Railway Company . This machine was sold in 1967 to the Swiss museum railway Blonay – Chamby .
- In 1928 machine no. 12s was delivered to the Albtalbahn . In 1934 this locomotive went to the Brohltalbahn (there No. II ). It was scrapped there in 1957.
Unlike the original Heeresfeldbahn version, the replicas were designed as wet steam engines.
Preserved copies
The Hanomag replica is on the Swiss museum railway Blonay – Chamby on Lake Geneva. The locomotive has not been operational for several decades, but has been refurbished by museum members since 2018.
The mallet locomotives 413 and 414 of the Chemin de Fer du Vivarais do not belong to this series. The two locomotives were built in Alsace in the 1930s.
