The three narrow-gauge diesel locomotives of the DB class V 29 were purchased by the DB in 1952 from the Jung locomotive factory for the Palatinate local railway lines Mundenheim – Meckenheim and Neustadt – Speyer .
construction
The construction failed: two identical drive units are closely coupled, on which a common driver's cab rests. The substructure is rotatably mounted on one frame with a bearing point, while on the other frame with two longitudinally displaceable bearings.
The A 8 L 614 engines came from Klöckner-Humboldt-Deutz , and the power was transmitted via a Voith gearbox, a reversing gearbox and chains on the two axles. This drive was identical to that of the Köf II . In addition, there was an auxiliary diesel (25 HP) for the auxiliary drives (three generators for locomotive and train lighting, a compressor for the air brakes and an air extractor for the suction air brake). These were mounted on a drive unit, while the other unit carried the batteries and the auxiliary air tanks for the brakes. The drive cranks regulated the amount of fuel injected via the injection pumps on both engines at the same time. This required an exact setting so that the motors ran synchronously.
The locomotives had no boilers , so that a heating car with a container filled with steam had to be carried on passenger trains .
history
The locomotives proved themselves in operation, so that in 1953 the speed could be increased to 42 km / h by changing the chain wheels. However, there were bearing damage in the first year of operation, and the locomotives were in the Ludwigshafen depot for almost four months in order to repair the too weak construction of the auxiliary machine. After the Ludwigshafen Railway was shut down, the V 29 951 was initially taken to the Speyer – Neustadt local railway and, after its discontinuation in 1956, the V 29 953 to the Regensburg – Wörth Walhallabahn . After they were discontinued in 1969, V 29 951 and 953 were scrapped.
The V 29 952 was converted to the Nagold – Altensteig route after the train brake had been converted to compressed air and the coupling to coupling hooks . There it was given a warning paint on the corners of the porch and driver's cab around 1960, first on one side and then on both sides. In 1967 it was sold to Mittelbadische Eisenbahnen AG (MEG), where it was used from Schwarzach as V 29 01 until 1980. There, too, the clutch first had to be adjusted. The warning stripes have been removed, and instead the locomotive has a decorative stripe around the front end. In the 1970s, it received new front lights and an orange paint job with a light blue decorative stripe that now ran all the way around the locomotive above the front lights. After the meter-gauge remaining operation was also discontinued there in 1980, it went to the German Society for Railway History (DGEG) in 1981 . After the DGEG narrow-gauge collection was dissolved, it was taken over and processed by the German Railway Association in 1997 . It has been operational again since 2001 and is in use with the old wine-red paintwork.
