Rail Track Grinding Main Line Grinding Phoenix Abrasives

The main benefit of rail grinding on the 10000 route miles of Network Rail is to shape the rolling contact with the train wheels, thereby increasing the dynamic stability of that contact. This also reduces the track forces as well as removing the cracks which otherwise might spread into the body of the rail. Modern trains impose very heavy longitudinal forces on the track formation

Rail Grinding Best Practice

Rail grinding is a process that is usually performed by railbound machines. These machines remove metal from the rail using rotating grinding wheels (stones). The volume of metal removed is dependent upon the number and arrangement of stones on each rail, the characteristics and condition of the abrasive in the stones, the application pressure on the

Track treatment fleet Network Rail

Grinding trains. A grinding train maintains the track and helps to increase the lifespan of the rail. These trains remove small layers of metal from the railhead, helping us to keep the track in good condition. Our new fleet was introduced in 2017 and offers increased metal removal due to more productive grinding at speeds of up to 15mph. The machines are modular, therefore can be attached
