The Wehrmacht diesel locomotives of the type WR 550 D 14 were shunting locomotives with hydraulic power transmission .
history
The four-axle locomotives with about 550 hp power and an axle load of 14 t was the most efficient from the program of shunting for the armed forces . However, due to the development of the Second World War, only three prototype locomotives were completed, one each from the manufacturers BMAG , Deutz and O&K . The Deutz engine had an eight-cylinder engine, the other two had six cylinders. The fluid transmission of the locomotives came from Voith .
No. 11118
The first of the three locomotives was No. 11118 built by BMAG. The vehicle was delivered in October 1941 and returned to the manufacturer for conversion work. In April 1942 it was put back into operation and in September it was transferred to Tobruk in Libya . Just two months later it was captured by British troops and in 1943 transferred to Palestine , where it was used on the Haifa - Beirut - Tripoli route. In 1944 it was taken over into the inventory of the British War Department with the number WD 70246 .
In 1946 the locomotive was parked in Haifa and scrapped in 1958.
No. 27307
Locomotive No. 27307, built by Deutz and delivered in May 1942, also went to North Africa in September 1942 . In October it burned down completely after an air raid and soon fell into the hands of British troops . Her whereabouts are unclear; it was probably scrapped shortly after the war.
No. 21304
The locomotive No. 21304 built by O&K was delivered in July 1942 and converted into an armored multiple unit (Pz.Tr.Wg. 16) at BMAG in 1943. A four-axle drive, each with a gun, was built on both sides of the locomotive.
In May 1945, the armored railcar was captured by the Polish army . The vehicle survived the war and was last used in uprisings in 1947 and 1948. In 1950, after repairs, it was included in the PKP's inventory with the number 870027 .
The armored railcar has been preserved in a museum in Warsaw since 1974 .
Constructive features
As with the two-axle WR 200 B 14 and three-axle WR 360 C 14 , the cab was at one end of the locomotive, and the porch was almost as high as this.
The diesel engine operating on a downstream gearbox and arranged under the cab dummy shaft via a driving rod , the third axis to. The power transmission to the other axes was carried out by means of coupling rods .
Two single locomotives of the WR family could be coupled to each other with the driver's cabs, also mixed types, and used as double locomotives . The control was carried out from a driver's cab, with the steering wheels connected by roller chains and a cardan shaft under the buffer beam .
