HSG-2 grinding train
The HSG-2's revolutionary technology allows up to 60 km of track to be ground non-stop. It produces virtually no sparks or dust during the operation and effectively reduces the noise emitted by rail traffic by 3 to 10 decibels. To supplement to its purely rail-machining role, in the future the grinding train will also be a diagnostics vehicle.

The Evolution and Application of Rail Profile Grinding
The elimination of rail surface defects through the use of rotating grinding wheels, i.e. rail grinding, has been used by freight railroads since its introduction by the Pennsylvania Railroad in the late 1930's. That application used the first rail grinder cars for the elimination of corrugations, engine burns, and batter at rail ends.

Rail Grinding Practices in North America
Preventive rail grinding typically requires rail grinding cycles of 25–35 million gross tons (MGT) in sharper curves and 50–70 MGT in tangents or shallow curves. At each grinding cycle, about 0.004 inch is removed from the rail center and 0.007–0.010 inch of metal is removed from the rail gage and field corners in a single pass.5 2. RAIL ...

In addition, to ensure the best contact of the wheel and the rail, grinding provides the required geometry of its transverse profile [1, 2]. Although predominantly the defects located on the rolling surface of the rails are removed by grinding, it is also necessary to note the significant influence of rail grinding on the defects of other groups.
