The steam railcar DT 1 of BBÖ (later series 3071 of the ÖBB ) is an originally as baggage railcars later than Tenderlokomotive run train . The Slovak state railway Slovenské železnice (SŽ) bought similar vehicles in 1940 as the M 273.1 series .
history

At the beginning of the 1930s, the BBÖ needed a locomotive that could be used universally in light express train service, in suburban traffic in large cities and on branch lines . Under the leadership of Alexander Lehner , head of the BBÖ design department, a rather unconventional vehicle was designed for this purpose. Between 1935 and 1938, the BBÖ procured 20 units from the Floridsdorf locomotive factory in Vienna ; the first ten machines were delivered to the BBÖ in 1935. The vehicles were designated as DT 1 ( D ampf T riebwagen), with the large luggage compartment behind the driver's cab . Although the railcars were also designed for light express train service, they were mainly used on branch lines and in local traffic, which is why they were nicknamed "Dorftrottel". In local traffic on the main routes around Vienna, the DT 1 were often lined up in the so-called "commuter" in the middle of the train formation between two cars, in order to be able to drive in both directions without moving the locomotive at the end stations.
After the connection of Austria to the German Reich , the vehicles that are now in the inventory of were Deutsche Reichsbahn were in the range 71.5 arranged. The machines were stationed in the Munich East railway depot and used either as heating or shunting locomotives or lent to works railways . Two machines did not survive the Second World War , the remaining 18 copies returned to Austria in 1945 . According to the numbering scheme of 1953, they were designated as series 3071 . The last representatives of the 3071 series were stationed in the Vienna area until they were retired in May 1968. Their areas of application here included the Franz-Josefs-Bahn , the Nordwestbahn , the Pressburger Bahn , the Nordbahn and local railways in the Weinviertel .
The only surviving example of this type is the DT 1.07. It is part of the holdings of the Austrian Railway Museum and is located in the Strasshof Railway Museum , where it was refurbished in the early 1990s and presented in working order again in 1993.
technical features
The luggage compartment and the completely enclosed driver's cab turn the vehicle into a railcar. It has an external control of the Heusinger type and an internal valve control of the Lentz type (Lentz valve control). The 1'B1 ' axle sequence enables equally good running characteristics in both directions of travel. An adjustable chassis suspension made it possible to partially transfer the axle pressure from the driving axles to the running axles (from 13 to 11 t). This in combination with a reduced water supply made it possible to use it on branch lines with a weak superstructure.
In order to save personnel, one-man operation was partly implemented technically, and the first 10 machines were originally equipped with oil firing. Because of the fuel costs, they were converted to coal-fired, but this made a heater necessary and the savings in personnel no longer necessary.
accident
Due to a broken rail, a passenger train derailed on May 1, 1963 on the Korneuburg – Hohenau local railway near Würnitz-Hetzmannsdorf. DT 3071.15 fell down an embankment.
