Climate snow plow
Air-conditioned snow plows are used to clear snow depths of up to 1.50 meters on tracks ; Before that, only snow depths of up to 0.40 meters could be cleared. This railway - Snow plows are after the Austrian designer and inventor climate Rudolf named, who invented and patented.
history
Until the 1920s, locomotives were equipped with snow clearing plates, which were only able to clear snow depths of up to 40 cm. The Austrian designer and inventor Rudolf air from Saalfelden mounted in the early 1920s on a Tender Schneeräumschilde, which was pushed by a pushing locomotive. This clearing system was operational from 1926 and opened up an improved way of clearing snow.
Technical possibilities
The climatic snow plow was pushed, the staff was in a closed, protected work cabin, the clearing speed was a maximum of 60 km / h and snow throw distances of more than 10 meters were possible both to the right and to the left. A clearing width of 4.80 meters could be achieved and snow clearing was made possible 8 cm above the track bed and 8 cm above the upper edge of the rail. From the second generation of the air-conditioned snow plows, an intercom system between the train driver and the snow plow team offered a means of communication and braking could be initiated from the operator's cab in the air-conditioned snow plow's work cabin .
Snow removal
The blades, divided in the middle, could be adjusted laterally and in height using compressed air at pressures of up to 8 bar. The plowshares were vertical in their basic position, wedge-shaped for clearing on both sides. With the movable clearing shields, it was possible to adjust the shields so that they could be cleared to the right or left. This was necessary to clear snow from double-track lines. In addition, they were equipped with a wedge-shaped lane clearer.
Two or three people were deployed to operate it: A route-aware chief conductor who was able to give the push locomotive instructions about the required speed via the signal system at the rear end of the snowplow and also gave instructions for the forward and return journeys. The operator of the snow plow and, if necessary, a helper were in the cabin next to the driving ladder.
countries
Austria
The first type of climatic snow plow, which was used in Austria in 1926, had a clearing width of 3.86 m. The carrier locomotive supplied compressed air via the brake line and the snow plow was mounted in front of the steam locomotive and had a work cabin .
In Austria, the so-called climate snow plow type Knittelfeld was manufactured in the main workshop of the ÖBB for the Arlbergbahn in the 1970s, another snow plow, the climate snow plow type Bludenz , is used on the Arlberg west ramp, which, due to the high volume of snow, is equipped with oil-hydraulic Systems for controlling the shields and not equipped with compressed air . This snow plow is easily recognizable by its fir green color, which differs from the standard red color of the other snow plows.
Germany
The Deutsche Reichsbahn first used air-conditioned snow plows in Germany in 1929 , which the Henschel company from Kassel reproduced after acquiring rights. Retired tenders and retired Bavarian electric locomotives were converted into air-conditioned snow plows. Two historical air-conditioned snow plows are in the German Steam Locomotive Museum and the converted E 36 02 electric locomotive in the Bavarian Railway Museum .
The Deutsche Reichsbahn built the Meiningen snow plow from 1968 to 1981, initially in the Reichsbahnausbesserungswerk (RAW) Halberstadt , and later in the Meiningen steam locomotive works in Thuringia . In 1994, 105 snow plows of this type were brought into the Deutsche Bahn AG by the Reichsbahn . In 1999, only 30 of these vehicles were left at Deutsche Bahn AG.
