12/4/2017· Three new grinding trains have been unveiled by Network Rail.Costing £36 million, they will be deployed across Great Britain to keep the track in good condition and provide passengers with a smooth, reliable journey.
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,
5/27/2017· Transitional grinding. Transitional grinding is a long term strategy (3-6 years) for steel rail.Its main function is transform corrective grinding to preventive grinding. This kind of grinding should go through several times grinding cycle, especially for nonstandard steel rail maintenance.
7/30/2007· Thus years ago, grinding of the rail surface used to be undertaken to remove corrugations and ensure a smoother ride. The advent of harder steels in the rail manufacturing process made this less important, such that in the UK towards the end of the 1990s grinding had virtually ceased altogether.
The rail profile weld grinder consists of a grinding unit coupled with an engine/electric motor and fitted to a light weight frame.The grinding unit can be moved up or down by a feed screw fitted to the frame.The frame is having two set of rollers right angle to each other attached at its both legs for to and fro movement of the grinder during grinding operation.
