 SRGM during 2022-23 in SC division.

For the first time in S.C.Railway, SRGM has been commissioned in SC
Divison
1. Importance of rail grinding and advantages: Rail Grinding is done to re-
profile the railhead taking into consideration the profile of the wheel for

optimisation of the rail wheel contact band and thereby making rail
wheel interaction favourable. This is expected to increase the life of the
rail and the wheel, apart from reducing the rate of generation of defects
in the rails. Indian Railway is using 20 stone grinders of RGI-IR20 Series of
Loram, USA Make grinding machine as gap grinder.
2. Switch Rail Grinding Machine (SRGM) salient features and functions:

 Plain track and curves
 Tracks in tunnels
 Track on bridges with or without guard rails (without removing guard rails

 Track on platform lines
 Switches, crossings /diamond crossings (with or without check rail
/guard rail)
