Group 121a was a series of eight steam railcars with the Kittel boiler system of the Grand Ducal Baden State Railroad , abbreviated to BadStB.

history

Around 1900 , the use of steam railcars was tested in Baden as an alternative to the use of passenger trains, guided by steam locomotives of the class Id . After a first attempt in 1902 with built-in group 133c is arranged railcars with boiler system Serpollet one for steam railcar decided in 1914 with Kittel boiler system to purchase. Steam railcars of this type had been in use for almost ten years on the Württemberg State Railways as class DW 1-17 . The first railcars were taken over in 1914 and were given the numbers 1000 to 1002. In 1915 another five vehicles followed , which were assigned the numbers 1003 to 1007.

The railcars proved to be extremely reliable in operation. At times they drove with up to three sidecars . The construction made it easy to maintain the technical system without special equipment.

After the takeover by the Deutsche Reichsbahn in 1925, the railcars were given the operating numbers 1 to 8 and were assigned to the Karlsruhe Railway Directorate . The railcar no. 6 was sold to the Oderbruchbahn around 1932 and designated there as 3-2001. In 1949 it came to the Deutsche Reichsbahn and was given the number DT 151 and was retired around 1956.

The railcars 1 and 8 were taken over from the Deutsche Bundesbahn . The first was taken out of service in 1951 and the latter in 1953. The railcars number 2 and number 3 came to the inventory of the French state railway SNCF in 1945 and were there in the eastern region as XDR 10102 and XDR 10103.

Constructive features

The boiler system coat consisted of a standing smoke tube boiler with a corrugated tube - firebox . A superheater was placed in the smoke chamber above the boiler.

The railcar itself was largely constructed like a passenger car . The wooden structure was built on a riveted steel profile frame . The cladding was done with sheet steel. Access to the compartment was via an end stage, while the boiler and the driver's cab were on the other side .

The driven wheel set was firmly mounted, while the wheel set was designed as a steering wheel set . The suspension was carried out by means of leaf springs .
