Refining Approaches to Corrective and Preventive Rail Grinding
While grinding to address rail surface conditions—RCF and SSCs—is a bigger driver than profile correction, CSX has found that profile conditions are a good guide to overall rail conditions. “We tend to find poor surface conditions wherever the profile is out,” Hampton said.
Rail Grinding Machine:A Basic approach SlideShare
Feb 14, 2014· Measurements and condition monitoring before grinding Measure the rail profile at nominated test locations with miniprof, Bar gauge, do DPT, take surface photos and measure hardness. while taking miniprof readings, the details such as LH/RH of rail and TP to be fed otherwise it will not be possible to identify the pre and post grind profiles.
Understanding Why, When and How Rail Grinding is Performed
