The Spremberger Stadtbahn No. 11 was a two - axle meter - gauge tank locomotive of the Spremberger Stadtbahn .

history

In 1925, the Borsig locomotive factory delivered the machine with the serial number 11 870 to the Spremberg Stadtbahn as its first and only superheated steam locomotive.

The locomotive was used on the so-called coal railway, which was used to deliver coal from the surrounding coal mines to industrial companies in the Spremberg city ​​area. After the light rail traffic was discontinued in 1956, the locomotive came to the Deutsche Reichsbahn and was upgraded for use on the Harzquerbahn in the RAW Görlitz . It was given the Reichsbahn road number 99 5001. This was the second occupation of this number, from 1949 to 1951 it was assigned to a former factory locomotive that had been built by Henschel in 1920.

For the distance use on the steeply graded track inventories, however, were too low, making it in operations during maneuvering, mostly at stations Nordhausen-Nord and Wernigerode-Westerntor, and service of factory outlets in Wernigerode remained until the locomotive 1967 z found has been.

However, it was not scrapped, but in 1973, after prior refurbishment in Wernigerode, sold to France to private customers. The new owner, who also bought the 99 5611 , wanted to use the locomotive on the museum railway Dunières - St. Agrève.

The locomotive never ran in France. Two reasons are given for this. On the one hand, the weak superstructure of this route and, on the other hand, the lack of approval by the authorities.

In 2010, the 99 5001, together with the modified 99 5611 , is in a hall in the Rhone Valley. The collection of Monsieur Prèvot is housed in Portes-lès-Valence. It cannot be visited.

The museum railway Dunières - St. Agrève, meanwhile neglected, has almost been demolished. Revived in 2002 after a new beginning, only French railcars run there.

technical features

The locomotive has a bar frame on which the boiler, which is 2,000 mm in the middle above the upper edge of the rails, rests, which is relatively high for a relatively small locomotive. Originally the machine had a Kobel chimney, which was soon replaced by a normal chimney.

The locomotive has a Heusinger control and piston valve, the driving wheel set is the second coupled wheel set.

Through a renovation in the Spremberg Stadtbahn workshop, the coal supply, which was originally limited to a maximum of 0.5 t, was increased on the two water tanks on the side of the boiler by adding an additional coal tank on the rear wall of the driver's cab.

For use on the Harzquerbahn, the locomotive, which originally only had a handbrake, was fitted with a Körting suction air brake for the train, a two-stage air pump for braking the locomotive itself using a compressed air brake, a steam turbine generator for electrical lighting, a bell and instead of the former central buffer coupling the coupling type of the Harz railways.
