The Hümmlinger Kreisbahn L1 and L2 belong to a delivery of nine locomotives of two-axle shunting locomotives from the Krupp locomotive and wagon construction factory from the mid-1950s. They had air-cooled diesel engines and hydraulic power transmission with a switchable secondary gearbox. Some locomotives are available as museum locomotives.

history

From 1952 to 1964, Krupp built 78 two-axle locomotives with hydraulic power transmission for light shunting. The locomotives were motorized differently, with an air-cooled engine from KHD or with a water-cooled engine from MAN . The locomotives from Krupp are not included in a list of types.

These locomotives with an output of 220 hp come from the second post-war program. Of these locomotives, which are manufactured exclusively with KHD engines, a total of nine locomotives were manufactured between 1954 and 1958. In addition to the delivery to the Hümmlinger Kreisbahn , the Rhein-Ruhr racing facility received two locomotives of this series, one each went to the Westphalian wire industry , HC Starck (used in the Laufenburg (Baden) plant ), Phoenix-Rheinrohr , Scheufelen paper mill and BBC Mannheim .

Constructive features

The locomotives had a machine front end and a driver's cab behind it. The Hümmlinger Kreisbahn locomotive that was first delivered had a smooth front end, while the HKB L2 had a bevel to improve the driver's viewing angle. The shunting staff had a ride to the side between the two axles.

All locomotives were equipped with an air-cooled twelve-cylinder four-stroke diesel engine from KHD . The power transmission took place with a fluid transmission from Krupp, in which the blades in the impeller of the converter could be adjusted for power and traction control. In addition, the locomotives had a rear-mounted gearbox, in which two gears could be shifted with a multi-plate clutch while driving . After this secondary and reversing gear, both axles were driven with a chain pinion and a roller chain .

commitment

Hümmlinger circular path

The locomotives were the company's first standard-gauge locomotives. The HKB L1 was delivered in 1956, the HKB L2 followed a year later. One locomotive was intended for normal operation on the re-tracked Hümmlinger Kreisbahn. For more heavy traffic, both locomotives should be able to take over the train together. The machines designed for the shunting service were too weak and too slow for the route service, and there was often excessive gearbox heating. Therefore, both locomotives were sold, the L2 in 1961, the L1 in 1979.

The HKB L1 is preserved today at the Heiligenstadt Railway Association .

Other preserved locomotives

Preserved locomotives are at today

In addition, a locomotive from the Rhein-Ruhr racing facility was erected as a memorial in Hilchenbach-Vormwald .
