DB and Vossloh expand their cooperation in preventive rail maintenance

Vossloh and DB Netz are continuing their successful cooperation in the field of preventive rail maintenance with the HSG (High Speed Grinding) technology developed by Vossloh. Following the successful collaboration in the current year, the scope of high-speed grinding for 2024 has now been extended by 1,000 km to at least 13,000 km. 

The focus of the work will again be on the most heavily used lines of the German network, the so-called high-performance network. In addition to the actual grinding work, DB Netz has again ordered the use of extensive digital measurement and analysis technology. During the crossing, important condition data is collected and evaluated in real time, and relevant information can be visualized in a web-based application, including concrete recommendations for action. This creates the basis for a transition from time-based to condition-based maintenance. 

The globally unique grinding process for preventive maintenance of the rail network allows an operating speed of more than 80 km/h on main lines. This allows Vossloh machines to "float along" with freight traffic at night, for example, making line closures obsolete. The grinding program can be individually adapted to the respective track condition. Under the current contract, for example, additional cross-sectional optimization has been carried out on some sections of track. 

Heike Junge-Latz, Member of the Board of Management responsible for Plant and Maintenance Management at DB Netz, adds: "We expect passenger and freight traffic volumes to continue to rise in the coming years, and we are constantly upgrading our network in response. The size of the German high-performance network will almost triple to over 9,200 km by 2030. By means of prevention using HSG technology, for instance, we will further increase the reliability of our network."
