The steam locomotives of the class B 1 were procured by the Reichseisenbahnen in Alsace-Lorraine in 1871. In 1906 the locomotives were classified in the class P 1.
history
With the takeover of the route network in Alsace-Lorraine, the acquisition of locomotives and wagons was necessary because the French had withdrawn all vehicles. Originally the twelve locomotives built by Strousberg according to the "Strousberg-Normalien" were intended for the Halle-Sorau-Guben Railway as numbers 16 to 23. However, they were no longer used there because the Reichseisenbahnen acquired them immediately after delivery. The locomotives were given the numbers 30 to 41 and the names of various German rivers.
In 1906 the locomotives were given the numbers 501 and 512. In 1912 the 504 and 509 were renumbered 101 and 102. All other locomotives had already been taken out of service at this point. In 1918, locomotive 102 was occasionally used as a wash-out locomotive in the Mühlhausen area.
Constructive features
The locomotives had an inner frame. The kettle was three-shot. On the rear shot sat the steam dome. The standing kettle had a Belpaire ceiling and a deep fire box that reached under the axles. The smoke chamber was expanded.
The two-cylinder wet steam engine was external and had an internal Allan control. The drive rod acted on the second coupling axle.
The suspension of the coupling axles is done by leaf springs over the axles. The spring assemblies were connected with compensating levers. The suspension of the barrel axle was carried out by a transverse leaf spring.
The locomotives were later fitted with a Westinghouse compressed air brake, a steam heating system, a wash-out valve, a sand spreader and an adjustable blowpipe .
The tender had a horseshoe water tank and a second water tank placed between the frames. This increased the amount of water carried to 9 m³.
