The class A 3 steam locomotives were purchased by the Reichseisenbahnen in Alsace-Lorraine in 1871. In 1906 they were classified in genus P 2.
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of the route network in Alsace-Lorraine, the acquisition of locomotives and wagons was necessary because the French had withdrawn all vehicles.
Eight locomotives were acquired from the Wiener Lokomotivfabrik G. Sigl , which were intended for the Alföld-Fiumaner Railway and were to be assigned numbers 35 to 40 as well as 39 and 40 with a second crew. The Reichseisenbahnen gave them the number 18 to 25 and the names of southern and central German rivers. The locomotives were used in passenger train traffic. Only two locomotives were renumbered in 1906, but they were retired by 1907.
Constructive features
The locomotives were of a common Austrian design at the time. The machines had an outer frame and a very deep three-section boiler. The steam dome was on the foremost boiler section directly behind the chimney. The standing kettle with its firebox hung far back.
The two-cylinder wet steam engine with Allan control was external. The drive rod acted on the first coupled axle. The drive axles were connected with a Hall crank .
The suspension is provided by leaf spring assemblies attached to the axle bearings. The springs of the coupling axles were connected by means of compensating levers.
The three-axle tender with a spindle brake was also of Austrian design. It held 8.5 m³ of water and 4 tons of coal.
