Rail Grinding Best Practice

Rail grinding is a process that is usually performed by railbound machines. These vertical and traction loading which cause the rail head to plastically deform. An unlubricated rail surface is subject to higher friction forces and therefore higher rates of plastic flow. As the contract stress exceed a certain limit, the metal at the near

Aug 15, 2020· In order to effectively simulate the rail grinding process, in this study, the rail specimens were directly cut from new U75V rail heads with the length of 800 mm, as shown in Fig. 2a. The rail head was composed of three curves with different radii: 13 mm, 80 mm, 300 mm (named as R13, R80, R300, respectively), as shown in Fig. 2b. The mechanical properties and chemical compositions of U75V

Grinding and Milling are Essential for Rail Quality

Jan 23, 2009· The Hatfield accident in the UK in 2000 was a wake-up call for railway administrations the world over. The derailment of an express passenger train with passenger fatalities was shown to have been caused by rolling contact fatigue (RCF), in which tiny cracks in the rail head extended down into the body of the rail, eventually causing a break.

Understanding Why, When and How Rail Grinding is Performed

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

Slippery rail Wikipedia

Slippery rail, or low railhead adhesion, is a condition of railways (railroads) where contamination of the railhead causes trains to experience less adhesion (grip). This can lead to wheelslip when the train is taking power, and wheelslide when the train is braking. The most common cause of contamination is fallen moist leaves that lie on and cling to the top surface of the rails of railway

Probing the effect of grinding-heat on material removal

Jul 01, 2020· With the aggravation of surface defects caused by RCF on the rail head, grinding technology was applied to commercial railroads for eliminating rail surface defects since the 1980s [2,5,10]. Since then, grinding technology has been frequently reported as an effective method on eliminating rail surface defects.

What’s the milling train and how will it Network Rail

The rail milling train renews track by grinding away the damaged top layer of steel on the rail. It has wheels with hundreds of cutting tips, which spin to shave off small pieces of rail. Doing this slowly means the train consistently shaves off all the defects as it passes.
