The locomotives No. 6 to 13 of the Bröltalbahn were triple - coupled, narrow-gauge tank locomotives . The machines were manufactured by Arnold Jung Lokomotivfabrik from 1891 to 1892. Locomotive no.6 came to the Deutsche Reichsbahn via the Trusebahn and was given the road number 99 4611 in 1949 .
history
The eight locomotives delivered by the Arnold Jung Lokomotivfabrik to the Bröltalbahn in 1891 and 1892 were the first large series of identical vehicles for the railway company. It was based on the construction of the Maschinenbau-Gesellschaft Karlsruhe from 1884 ( Bröltalbahn No. 5 ). The construction proved its worth, so that in 1899 four more machines of this type were delivered with the locomotives No. 14 to 17, this time by Orenstein & Koppel .
With the delivery of the locomotives No. 31 and 32 and No. 51 to 53 in 1923, the locomotives 9 to 12 were decommissioned. Locomotives 7, 8 and 13 were retired in 1953.
The locomotive No. 6 was sold to the Trusebahn in Thuringia in 1942 . Before that, however, it was necessary to re-track the locomotive from 785 mm to 750 mm. After the management of the Trusebahn took place on April 1, 1949 by the Deutsche Reichsbahn , the locomotive was given the road number 99 4611. The locomotive was in service on the Trusebahn until 1957. An operation on the Nauen-Kriele route failed due to the wheel set traveling mass of 6 t being too high. It was therefore moved to Burg in the same year . It was in service on the routes of the former small railways in the Jerichow I district until 1962. It was retired on May 17, 1965.
Constructive features
The locomotives had an outer frame.
The kettle had a Crampton standing kettle. The large steam dome with the flat slide regulator and two pop safety valves sat on the back of the long boiler. The sandpit sat directly in front of the steam dome. The hand-operated sand spreader sanded the center wheel set. The steam pipe sat on the standing kettle and was fed directly from a steam outlet.
The two-cylinder wet steam engine was arranged at a slight incline and worked on the middle wheel set. It was controlled by an Allan eccentric control.
The chimney was of the Prüsmann type. The Latowski steam flare was arranged on a console in front of the chimney.
Originally the locomotive only had a handbrake. 99 4611 received a Knorr compressed air brake from the Deutsche Reichsbahn . The air pump was placed to the right of the smoke chamber and the main air tank between the sandpit and chimney.
The driver's cab had folding doors and a ventilation attachment on the roof arranged transversely to the direction of travel. The feed water was housed in two water boxes on either side of the boiler. The coal supplies were in the coal box behind the driver's cab.
