The DR series V 15 (from 1970: series 101 ) were diesel locomotives of the Deutsche Reichsbahn for light shunting service. The locomotives were also supplied to industrial companies as the V 18 B. A more powerful version was put into service by the Deutsche Reichsbahn as the class V 23 (from 1970: class 102.0 ).
history
At the beginning of the fifties, some small locomotives of performance class II (Kö II, Köf II and N 4) were built to cover the war-related shortage of locomotives. In addition, the Deutsche Reichsbahn added a light diesel shunting locomotive with an output of 110–132 kW (150–180 hp) to its catalog of requirements. This machine was intended to replace the old small locomotives used for shunting and the widespread steam locomotives in the subway stations. In 1956, the LKM Babelsberg presented a new 75 kW (100 PS) locomotive based on the well-known small locomotives with mechanical power transmission, an elevated and closed driver's cab. The small locomotive, known as the V10B , had wheelsets with a diameter of 900 millimeters and was intended for operation on works and connecting railways. The locomotive shown did not quite meet the expectations of the DR, which still demanded changes.
V 15
In 1955 the industry delivered a prototype locomotive (type designation N5) for testing to the Deutsche Reichsbahn. As requested, this locomotive was equipped with a newly developed fluid transmission and a diesel engine with 110 kW (150 PS). The machine, run as V 15 101, was not taken over by the DR after the tests had been completed because of its different, low frame construction and the low-lying driver's cab (similar to the LKM N4 ), but sold to the Institute for Rail Vehicles Berlin-Adlershof (IfS). The experience gained ultimately led to the production of the pilot series (V 15 1001 to 1005) and the first small series (V 15 1006 to 1020) with an engine output of 110 kW (150 hp) in 1959/60. Further series followed from 1960 with a 132 kW (180 hp) engine as a sub-series V 15.20-21. The most noticeable change was the enlarged drive wheel diameter from V 15 2026 to 1000 mm. Reinforced vehicles delivered to the industry and sidings were as V 18 B , respectively. The vehicles delivered to the Deutsche Reichsbahn were numbered as V 15 2201–2349. The locomotives all proved themselves very well and were produced in various lots up to 1964.
Little by little and during the rebuilding program from 1975 onwards, the V 15's worn out diesel engines were replaced by the 220-hp V 23 unit and an improved twin-converter GSU 20 / 4.2 fluid transmission was installed. The conversion work was carried out in the responsible RAW Halle / Sa. The locomotives modified in this way were incorporated into the sub-series V 23.0 and thus 101.5–7. The numbers were assigned according to the order in which they were converted. The old company numbers were no longer taken into account.
V 23
In order to meet the desire for higher traction, LKM Babelsberg developed a locomotive with the factory designation V 22 B in 1966 , which in turn was based on the basic concept of the previous model. However, from 1967 onwards, only factory and connecting railroads received the locomotive equipped with a new, more powerful gearbox and a completely redesigned 162 kW (220 PS) modular engine. It was not until 1968 that the DR put the first locomotive of the new design, known as the V 23 001, into service. The DR procured a further 79 locomotives (V 23 002 to 080) from LKM by 1970. The DR did not make any further purchases because the newly developed 102.1 series was produced and added to the inventory from 1970 . The locomotive was manufactured for industrial and works railways until 1976.
Constructive features
The locomotives had a completely welded sheet metal inner frame made of 20 mm thick sheet metal with a frame cover sheet with openings for the diesel engine and gearbox and reinforced head sections with normal UIC pulling and pushing devices. The vehicle frame is supported by leaf springs and spring tensioning screws on the two slide-mounted wheel sets .
The front section houses the cooler, diesel engine, air compressor, fuel tank, sandpit and exhaust silencer. The air tanks are installed on the right and left below the walk-around for maintenance of the machine system. The battery boxes are located behind the front maneuvering steps. From the 102.0 series, an oil-heated preheater was installed in a box on the left under the driver's cab.
In the first series, the diesel engine 6 KVD 18 SRW with 110 kW up to the V 15 1020 is used to generate power, from 1960 the same engine with increased output with 132 kW and two-stage regulator. From 1966 transition to the newly designed 6 VD 18 / 15-1 SRW 1 from the Roßlau engine factory . The engine is a 19-liter, six-cylinder, pre-chamber in-line engine without supercharging and develops 220 hp (162 kW) at 1510 rpm with a 150 mm bore and 180 mm stroke and an adjustment controller.
The power flows from the motor via a torsionally flexible coupling and a short cardan shaft to drive the fluid transmission GSR 12 / 3.7 with a converter and two couplings. Later, the two-converter gearbox GSU 20 / 4.5 with a starting converter (up to 16 km / h) and a march converter (for 16–40 km / h) was installed. The gearbox is switched automatically, depending on the driving speed.
The reversing gear , which enables the direction of travel to be changed, is flanged directly to the fluid transmission . The reversing gears have been revised and improved several times over the years.
The reversing gear drives the jackshaft directly and transmits the torque to the two gear sets via coupling rods .
The diesel engine is connected directly to the radiator fan, the air compressor and the alternator via a belt drive .
The locomotive has an automatic single-chamber compressed air brake, type Knorr, and a non- automatic , direct-acting additional brake with additional brake valves. The two sets of wheels are braked from the front on one side. The mechanical handbrake acts on the linkage of the air brake.
The locomotives have a 24-volt electrical system, which is supplied by a direct current generator and lead-acid batteries . The cranking of the diesel motor is electrically connected to a 15 PS - Starter The locomotives are partly with safety driving circuit and shunting been equipped.
As a special feature, some locomotives of the V 23 series, which were produced for use on connecting and industrial railways from 1974, were already equipped with an electropneumatic multiple control ex works. This enabled two locomotives, electrically coupled, to be controlled from one driver's cab. It did not matter how the locomotives were in relation to each other. The drive and switching commands were transmitted electrically, and the units were operated pneumatically. In addition to the multiple control device, the machines had a main air tank line and automatic monitoring of the diesel engine.
commitment
The locomotives could be found in use on the entire route network of the Deutsche Reichsbahn. The machines were used particularly in light shunting operations at small train stations, in track construction and in maintenance operations. Many locomotives of this type were delivered to utility and connecting railways.
The locomotives were maintained in the repair shop in Halle and in the home offices. Another repair shop was located in Tharandt , which only reconditioned factory locomotives.
After reunification, the 101 series locomotives were classified as the 311 series from 1992, the DR series 102 was re-designated as the DB series 312. The 311.0 were the pre-series machines with 110 kW. The 24 311.1 locomotives had an output of 132 kW, the 225 units of the 311.5 series had an engine output of 162 kW. The more than 150 locomotives of the 312.1 series were much more modern and outwardly differed significantly from the 311 series.
In the meantime, the entire inventory has been decommissioned, scrapped or sold to other operators by Deutsche Bahn AG (DB). Some machines have been preserved at the DB as equipment or rail service locomotives. A relatively large number of different machines of this design can be found at works railways , railway associations or railway museums (the 102 001–5 (V 23) in the DB Museum Halle (Saale) ). Since June 2017, a V 22 from the former VEB Getreidewirtschaft Gotha has graced the roundabout known as the PIKO roundabout at the entrance to the company premises of Piko Spielwaren GmbH .
The 312 047 is preserved at the Buckower Kleinbahn .
