The approximately 70-meter-long rail grinding train will be on the S 40 between Herzogenburg and Traismauer from June 29 to July 2 to give the rails a new, ideal profile with its 2,500 horsepower. Grinding brings benefits to both residents and ÖBB customers.

The noise level along the rail lines is reduced by smoothing the rails, and in the wagons, it makes travelling even quieter and more pleasant. For ÖBB, rail grinding also brings economic benefits, as the performance and service life of the rails are extended many times over.

The ideal profile for rails and switches

Small slip waves or deformations of the rail head form on the rail surface as a result of trains passing over it. These fine unevennesses are a source of noise, which also stress the vehicles and rail superstructure through vibration. The 24 grinding motors on board the train restore the rails and switches to their ideal profile. Around 0.3 - 1 mm is ground off. In one night, the rail grinding train covers a little more than three kilometres. The track sections are selected in advance using a special measuring train. This high-tech device shows the experts exactly where the grinding train is to be used.

ÖBB asks for an understanding regarding noise development

The deployment of the rail grinding train is meticulously planned. The work will take place at night due to the heavy rail traffic and influence the train traffic as little as possible in the interest of the passengers. ÖBB is making every effort to keep disruptions to a minimum but asks for your understanding that noise development cannot be completely avoided. The rail grinding train is equipped with an extinguishing device for safety against fires on embankments.
