The Deutz A6M 517 R locomotives were meter-gauge , diesel-hydraulic locomotives with the B wheel arrangement . They were used on various small railways.
history
Klöckner-Humboldt-Deutz was one of the main manufacturers of the Köf II . Using the existing technology, a type of locomotive for meter gauge railways was developed. Unlike the Köf II, the driver's cab was above the frame and not at the end. A first locomotive was delivered to Herford's Kleinbahn as Köf 12 in 1951 , and a second locomotive (Köf 14) two years later. Euskirchener Kreisbahnen (EKB), which formerly belonged to the former West German Railway Company (WeEG), purchased two locomotives (V 21 and V 22) in 1954, these could be coupled to one another via a shaft connection and driven from a driver's cab. In 1955 two more locomotives (V 23 and V 24) were delivered. At the same time, the Geilenkirchener Kreisbahn (GKB) , which was formerly also part of the WeEG, acquired two locomotives (V 10 and V 11) without the possibility of multiple traction.
HKB Köf 12 and Köf 14
On July 20, 1951, the Herford small railway received a diesel locomotive as Köf 12, which should replace the steam traction in freight traffic. As this locomotive had proven itself, a second locomotive was ordered and delivered as Köf 14 on September 29, 1953. This enabled the last steam locomotive to be parked. After the railway was closed, Köf 12 went to Inselbahn Juist in 1966 , where it was given the name CARL in a second line-up, and Köf 14 to Sylter Inselbahn (L14). After this line was discontinued, it also came to Juist in 1971 and was named HEINRICH, also in the second line-up. After the Juist Island Railway was discontinued in 1982, Lok CARL was erected as a memorial in Juist until 1988. After being placed in a shed, it was sold to the Märkische Museum-Eisenbahn in 2014 . In 1982, HEINRICH went to the Montreux-Berner-Oberland-Bahn in Switzerland (Tm 2/2 2) and in 2010 to the museum railway Chemin de Fer de la Baie de Somme in France.
EKB V 21 to V 24
The Euskirchener Kreisbahnen received two locomotives with multiple controls on July 27, 1954 and September 12, 1955. After the rest of the business was closed on December 31, 1965, they were sold in 1966. V 21 and V 22 went to the Grafschaft Hoya public transport company for narrow-gauge operation on the Bruchhausen-Vilsen-Asendorf route and were given the numbers V 122 and V 121. They were given additional raised buffer beams on one side with standard gauge buffers and drawbars to directly couple jacked wagons to be able to. In 1971 this freight traffic was stopped. The V 121 was converted to standard gauge in 1973 and used on the Eystrup – Syke line of the VGH. In 1984 this locomotive was sold to the Montreux-Berner-Oberland-Bahn in Switzerland and backtracked to 1000 mm. There it is used as Tm 2/2 3. The V 122 fell by the wayside, was acquired by the German Railway Association in 1980 and used as the V 3 on the museum railway from 1982 onwards.
The V 23 and V 24 were sold to the Charbonnage d'argenteau mine in Belgium. In 1979 hard coal production was stopped there. Tourist trains were now running on a section of the Trembleur – Warsage line. This train has now been discontinued. At the turn of the millennium, both locomotives came to the Train du Bas-Berry in France, where they are used under the serial number (56115 and 56116).
GKB V 10 and V 11
The Geilenkirchener Kreisbahn (GKB) had to rationalize the remaining rail operations in the 1950s. In 1953, the Geilenkirchen - Alsdorf line had lost passenger traffic to the competition on the road and was only served on the Geilenkirchen - Puffendorf section for freight traffic. The remaining freight traffic was more and more limited to seasonal peak times in agriculture . Thus, the remaining were steam locomotives of the type mallet Rimrott uneconomical, although they had been worked up again in 1945 fundamentally.
So in 1955 the two locomotives were procured and designated as V 10 and V 11. In contrast to the Euskirchen locomotives, they had no multiple controls and no transition doors on the rear wall of the driver's cab. After a few years, GKB made some adjustments to the operating conditions in the form of high-lying buffer beams. Thus it was now possible to couple the machines with jacked up standard-gauge freight cars without an intermediate car . In addition, the locomotives received rear-view mirrors to make it easier to maneuver at the trolley pit. In this form, the V 10 and V 11 were in use on the remaining GKB routes until the end of freight traffic. In 1959 they received support in the form of the VT 100 , which was converted into a towing vehicle , which was dispensed with due to the suspension of passenger traffic planned for 1960. At the end of the 1960s the V 10 was parked damaged.
In the first years of the museum's operation on the GKB, in 1969 still through the Association of West German Narrow Gauge Railways (VWS), from 1970 through the Interest Group Historischer Eisenbahnverkehr e. V. (IHS), the V 11 also hauled the museum trains before the steam locomotive 19 was available from July 1971 . When GKB's narrow-gauge operation, which was last limited to Geilenkirchen station, was discontinued in 1973, the locomotives were brought to Togo via a Hamburg intermediary to Dyckerhoff & Widmann AG (DYWIDAG) for the port expansion in Lomé . For historical reasons, the railway there had the same technical parameters (gauge, coupling system) as the GKB, which made it easier to use there. Togo was from 1884 German reserve was and the local trains as well as the Geilenkirchener circular path of the Szczecin Construction Lenz and Co. built.
After the completion of the new port by DYWIDAG, the machines remained with the State Railroad Chemins de fer du Togo (CFT), but only the former V 11 was used as the CFT H 9 for a few years. In 1985 it was parked in Lomé station, the sister locomotive V 10 was scrapped. In 2001 the V 11 came to the IHS and has been in the process of being refurbished since 2003; it is planned to restart it.
In 2019, the refurbishment was completed in the last operating state of the GKB and the V 11 has been in operation since autumn 2019.
August Thyssen Hut
There were two locomotives at the August-Thyssen-Hütte in Duisburg. Little is known about them. In 1957 they had failed, the GKB V 10 was on loan for them.
Constructive features
The A6M 517 engine is a water-cooled six-cylinder four-stroke engine with cylinders arranged in series. A Voith L 33 U with a flanged reversing gear was used as the gearbox. It is a hydrodynamic three-speed transmission. The power is transmitted to the axles via duplex roller chains.
In the case of locomotives with multiple control, the control of the engine speed is transferred between the locomotives using a cardan shaft. In terms of braking technology, the brake line and the main air reservoir were connected with two brake hoses. There was also a connection for the sand spreader air and a cable for the cab lighting. At the end of the cab there was a transition door with a transition sheet. The reversing gear had to be operated individually on each locomotive.
The locomotives originally did not have a train brake.
