MGT annual traffic), the return on investment (for rail grinding) was approximately 50%. For heavy traffic conditions (50 MGT annual tonnage), the return on investment (for rail grinding) was over 85%. In both cases, rail profile grinding, and its associated extension of rail life, was found to be economically viable.

the light rail tracks at walking pace. Details of work are as follows: • Grinding of the rail to remove minor defects (small amounts of metal) and maintain the profile (shape) of the track. • Grinding removes manufacturing residue from the newly built track.
This paper presents a newly developed modeling approach that is intended to provide a theoretical understanding of the rail grinding process and allow the prediction of rail grinding behavior and performance. The modeling is a bottom-up approach that starts from individual cutting grains and builds up to the rail grinding train level.

Abstract： The large freight volume and high transport density of railway freight lines leads to the frequent occurrence of rail diseases. It is necessary to grind the rail timely to improve wheel-rail relationship. Based on profile data of worn rail in different section, this paper adopted the Frechet distance method to construct the selection model of the representative worn rail profile.
Profile Grinding Goals • Top of rail should never have a radius less than 8" – Reduced running band can result in high stresses and rail surface fatigue (spalling) – Running band should be between 1 1/4 and 1‐3/4 inch on all rails • Reduce plastic deformation and metal surface fatigue
Rail grinders work by using a circular grinding stone, that are situated underneath the equipment right above the rails. These stones wear out extremely quickly and usually only last a few hours before needing replaced.
