The class D VI locomotives were light, two - coupled wet steam tank locomotives of the Bavarian State Railways . Maffei delivered the first 30 locomotives from 1880 to 1883, and Krauss delivered 23 more by 1894.
history
The class D VI locomotives were procured for flatter local railway lines with a maximum permissible wheelset running mass of 12 t.
The first 44 locomotives did not have side storage tanks. The water was housed in a frame water tank, the coal in the driver's cab. The last nine locomotives, on the other hand, were built with short storage tanks on both sides in front of the driver's cab. This increased the water supply from 1.8 to 2.3 m² and the coal supply from 0.5 to 0.8 t.
The Bayreuth was built in 1882 by Maffei in Munich with the serial number 1300. It was retired on December 12, 1900 in Bavaria and sold to Schuckert & Co. in Nuremberg. From there it was shipped to Norway. It carried goods on the Kykkelsrudsbane for the Glommens Træsliberi pulp mill there . In 1918 it was awarded for a short time to the Mørkfoss / Solbergfoss plant on the Askim – Solbergfoss railway line , after which it was banned from traveling on the subsequent Indre Østfoldbane . In 1923 Glommens Træsliberi burned down. It was one of several fires over the centuries. The fire broke out in the office and spread to the engine shed. One of two locomotives could be recovered in time, which Bayreuth burned.
In the 1920s, some D VI were used in the Palatinate as ship bridge locomotives near Speyer and Maximiliansau .
In 1925, the Deutsche Reichsbahn took over 26 vehicles as the 98 75 series , five of which had storage containers on the side. They were taken out of service by the end of the 1920s and some were sold on as factory locomotives.
The locomotive no. 83 "Berg" (98 7508), delivered by Krauss in 1883, was last used in a peat factory in Raubling and was only taken out of service in 1964. This machine is the only example of its series that has been preserved and is in the care of the DGEG in the Neustadt / Weinstrasse Railway Museum .
Constructive features
The D VI locomotives were designed with a riveted sheet metal frame designed as a water box.
The long boiler was riveted from two shots, the fire box with a square cross-section was placed between the frame cheeks. Two steam jet pumps were provided for feeding the boiler.
The external two-cylinder wet steam engine was equipped with a Stephenson control; The second wheel set was chosen as the driving axle.
For the first time in Bavarian locomotives, rotating plates and suction air brakes of the Hardy type, but in some cases Westinghouse air brakes as well , were used on the D VI . Some specimens also had transition bridges; What was unusual at the time was the arrangement of the sandboxes below the running plate between the coupling axles.
Trivia
The "Berg" locomotive is used in front of passenger trains in the film Rascal Stories . The locomotive was already in operation at the time of the action and about 80 years later at the time of the filming.
