Upward travel
High-speed runs are test programs that are carried out before new railway lines or vehicles are put into operation in order to prove their operational safety at the maximum permitted line speed in the future.
The route is traveled repeatedly during the upward movement. The first trip takes place at low speed. During each test drive, all essential parameters such as the way the vehicle is running on the track , the position of the contact line and the electrotechnical parameters are monitored and recorded. Only when the operational safety has been proven will the next trip take place at a slightly higher speed. The last trip is at least ten percent above the route or vehicle maximum speed.
Examples of high speed runs
- Before the ICE world record run on May 1, 1988 : The high-speed attempts had already started in the summer of 1985 and after numerous trips over 200 km / h led to the German record on November 19, 1985 with 324 km / h. The high-speed runs for the world record began after partial completion of the new Würzburg-Fulda line on April 22, 1988 at 220 km / h and led to the world record of 406.9 km / h on May 1.
- For the commissioning of the high-speed line from Nuremberg to Ingolstadt in 2006: The high-speed trips took place on eighteen days from December 1, 2005. The highest speed achieved was 330 km / h.
- For the commissioning of the Katzenberg tunnel in 2012: The high-speed drives were carried out from September 17 to October 5, 2012 up to the decrease speed of 275 km / h. Commissioning took place on December 4, 2012.
- On the new Erfurt-Gröbers line , the high-speed rides took place from September 1st to 19th, 2014 at a speed of 330 km / h. Together with other test and demonstration drives, around a thousand drives were carried out up to the opening drive on December 9, 2015.
- During the high-speed runs for the LGV Est high-speed line, the Eckwersheim railway accident occurred twelve kilometers from Strasbourg on November 14, 2015 , when the test train derailed in the curve before merging into the existing line. Eleven fatalities and 42 injured, including four children who accompanied members of the test team without permission. The cause was excessive speed (at the corner entry 265 km / h instead of the 160 km / h permitted in the curve or 176 km / h with the ten percent excess). The train control was switched off in order to allow the line speed to be exceeded from 320 km / h to 352 km / h.

Accessed on October 28, 2013: “During the high-speed runs, the speed is gradually increased up to the prescribed maximum route speed (300 km / h). As part of the technical approval and to ensure the greatest possible safety, the measuring train must travel ten percent faster than the planned maximum speed. The running behavior of the vehicle and the interaction between pantograph and overhead line are checked in accordance with regulations as part of the high-speed drive test program. "
