The 716 series from Deutsche Bahn AG is a self-propelled high-performance snow blower . It was specially procured for the high-speed route Hanover – Würzburg , where a snow clearing vehicle was required that can be quickly on site and achieve a high working speed.
In November 2005 716 001 was relocated from Fulda to Munich after the milling machines were only used occasionally on the high-speed route . 716 002 remained in Fulda.
The 716 501-2 (Ex 40 50 949 4100-3 SSF 41), which was manufactured by Rolba in 1980, does not belong to this series of vehicles .
Operational
Due to the infrequent use on the high-speed route Hanover – Würzburg, the two snow blowers from Fulda and Munich-Pasing are used throughout Germany. After delivery they were stationed in Fulda and Hildesheim.
The concept for the high-speed route provided for clearing the route in parallel with up to 80 km / h if necessary. In the case of transfers without an activated centrifugal unit, the vehicles are allowed to travel at a speed of 120 km / h. Today the maximum speed in spin mode is limited to 30 km / h.
Technical
When delivered, the snow blowers with a clearing capacity of 16,000 tons of snow per hour were considered to be the most powerful snow blowers on the rails in terms of speed and clearing capacity. The bogies were obtained from Kaelble -Gmeinder in Mosbach, the hydrodynamic gearbox comes from Voith in Heidenheim and the centrifugal unit from Beilhack in Rosenheim . The two vehicles were assembled in the DB factory in Meiningen , which also manufactured the vehicle frame and body .
At a snow depth of 50 cm, a clearing speed of 25 km / h is achieved. The clearing width is 5.54 m, the snow is thrown 40 m.
Car body
The vehicle has two bogies, each with two driven axles. The chassis frame carries the body, which can be swiveled 180 ° around the vertical axis. There is a flat engine room in the car body . The spacious driver's cab is also mounted on the body. The sling set was installed in front of the driver's cab. The car body was painted yellow, which has now been repainted in traffic red, while the frame and the bogies are black.
Sling set
Two throwing paddle wheels attached to each other are the center of the snow blower. Two small pre-cutting propellers are attached above and in front of the paddle wheel. The vehicle has a clearance width of 5 meters, this is due to the fact that there is a track center distance of 4.7 meters on the new line. The clearing width is achieved using packer plates, which are located on the outside of the centrifugal units and can be hydraulically extended. A track plow is also available.
drive
The 716 series has three same twelve-cylinder - diesel engines from Daimler . Each has an output of 405 kW. One drives the axle drives of all four wheel sets via a torque converter and cardan shafts , the other drives the slingshot devices via a gear drive . The transfer case for the drive is located at the pivot point of the vehicle.
