The vehicles of the SŽ series M 273.1 were steam railcars of the Slovak State Railways Slovenské železnice (SŽ).
history
The history of the vehicles goes back to the BBÖ DT 1 , which was ordered in 1934 by the Austrian Federal Railways as a replacement for motor vehicles with internal combustion engines. In 1940, the then state railway of Slovakia bought six such vehicles from the Floridsdorf locomotive factory for express train traffic between Bratislava and Prešov . They were at home in the Zvolen depot .
The steam railcar had a range of 1,000 kilometers plus water hold. With a load of 109 t, the M 273.1 reached a top speed of 100 km / h on the flat, and 55–60 km / h on a gradient of 15 ‰ with the same load.
After the Second World War , the vehicles were part of the Czechoslovak State Railways (ČSD) inventory . In 1953 and 1954, the vehicles were retired and scrapped.
technical features
The vehicle's steam boiler is a completely normal steam locomotive design, just like its fittings. He supplied the feed pumps with mixing heaters (as in the 534.0 series locomotives ).
The steam engine was two-cylinder with Lentz valve control , which was driven by a Heusinger control.
The drive wheels of the vehicle were firmly mounted, the two wheels, however, had a side clearance of 60 millimeters. The reset device was provided by leaf springs .
The whole vehicle was surrounded by a black coat. All controls were designed for one-man operation, and the vehicle could also be operated from both sides.
