In between 1896 and 1909 procured Royal Württemberg State Railways , abbreviated KWStE under whose head of the mechanical engineering offices Eugen Kittel , a total of sixteen similar steam railcar - a unique piece as a model and small each different advanced series - as DW 1-17 referred were, where DW stood for steam car . They were intended for shorter branch lines in southwest Germany. The steam railcars of this series equipped with a Kittel boiler are colloquially, together with other similar steam railcars, also referred to as Kittel steam railcars .
history
In 1895 the KWStE decided to build the first steam powered rail car near Decauville , which went into operation in 1896 and was equipped with a Serpollet boiler . Another six similar railcars , also with a Serpollet boiler , were built by the Esslingen machine works independently between 1900 and 1903.
Since the coal-fired Serpollet boiler, in contrast to automobile and commercial vehicle traffic, as well as tram traffic in full-line use, did not convince, Eugen Kittel himself developed a standing boiler , the Kittel boiler. This was installed in the six Esslingen railcars between 1905 and 1908.
Due to the positive experience with the Kittel kettle, the KWStE ordered another nine such vehicles, the DW 8 to 14 and the two DW 16 and DW 17, which were equipped with a Kittel kettle from the start, but with the new design Kittel head patented by Eugen Kittel , instead of the straight outer shape like this one had the DW 1 to 7 and also the similar CZm 1/2 31 of the Uerikon-Bauma-Bahn (UeBB). These were delivered between 1905 and 1909
In 1909, DW 1 in Esslingen was reworked so comprehensively that it can also be interpreted as a new building. Its external appearance was adapted to DW 2 to 7. In addition to a smock kettle, it also received the new name DW 15.
DW 6, DW 7, DW 9 and DW 15 to DW 17 were included by the Deutsche Reichsbahn as 9 to 14 in the inventory of the Reichsbahndirektion Stuttgart and in the 1930s they were partially retired or sold.
The railcar number 12, formerly DW 4, was sold in 1922 to the Kleinbahn Vechta – Cloppenburg and scrapped there in 1925 after an axle breakage.
Railcar number 9 came to the French state railway Société nationale des Chemins de Fer Français in 1945 and was used there in the eastern region as the XDR 10109.
No steam powered rail car of this series was preserved.
Other similar railcars
Eight similar vehicles with a Kittel head and Kittel kettle were delivered by the Esslingen machine factory to the Grand Ducal Baden State Railways as class 121a in 1914 and 1915 , after Esslingen had already produced a prototype with a Serpolet kettle as class 133c in 1902 , similar to the DW 1 to 6 and the UeBB CZm 1/2 31, was delivered.
For more companies, Maschinenfabrik Esslingen provided further ten similar examples, initially with Serpollet boiler, then with Kittel boilers, including the CZm half 31 of UeBB, who is the only Kittel steam railcar operable at the Heritage Foundation SBB preserved is.
