Locomotives 1 to 7 of the Rheinau-Hafengesellschaft were shunting tank locomotives that were originally intended for operation in the port of Mannheim . In 1904 they became part of the Grand Ducal Baden State Railways and were classified in class X a . The locomotives were retired by 1925.
history
Starting in 1898, the private Rheinau-Hafengesellschaft acquired seven triple-coupled shunting locomotives from the Maschinenbau-Gesellschaft Karlsruhe for operation on the connecting railways of the port area . The locomotive with good steam generation and small wheels was optimally designed to serve the many sidings in the port area with many shunting trips. With the takeover of the port by the Grand Duchy of Baden in 1904 , the Baden State Railroad was entrusted with operational management. The locomotives were classified in the newly created class X a. In the preliminary redesignation plan of the Deutsche Reichsbahn from 1923, six locomotives were still listed as 89 501 to 89 506. It was no longer redesignated in 1925; the locomotives had been replaced by type X b machines .
Constructive features
The locomotives had an internal sheet metal frame. The three-shot long boiler had a smooth outer barrel. The steam dome sat on the middle boiler section. The inlet pipes were inside. The Ramsbottom Wöhler safety valve was on the standing boiler.
The horizontally arranged two-cylinder wet steam engine worked on the central coupling axis. The Allan controls were external.
The leaf springs were below the axles. The spring assemblies of the first and second coupling axles were connected by compensating levers. The wheelbase of the three axles was different. Between the first and the second axis it was 1600 mm and between the second and third axis 1700 mm. The throwing lever brake acted on the second and third axes.
The sandpit was on the back of the boiler. The central axis was sanded from both sides. The water boxes were arranged on both sides. The coal container was on the left in front of the driver's cab. Due to the large amount of supplies (4 m³ and 2.2 t coal), the locomotive could remain in operation for a relatively long time without having to replenish supplies.
