It’s primary function is to restore the rail profile by removing irregularities, including mill scale and superficial defects occurring during operations, which helps to improve the geometric quality of the track, rail wheel contact, ride quality and reduce very high dynamic loads, noise and vibration of Metro Trains.
The service life of the rails will get extended by 25 per cent with preventive and curative grindings, the release said.
