Rail Grinding Engineering
The blending of theory and practice in modern rail grinding
Modern rail grinding practices have developed largely through a combination of field experience and intuitive speculation. Many theories related to crack initiation and growth have been proposed through the decades, and those concepts have been cleverly extended to the field of rail grinding to form the basis of the practice known as 'preventive grinding'.

Rail Grinding and its impact on the wear of Wheels and Rails
Rail Grinding and its impact on the wear of Wheels and Rails 3 2 The wheel/rail contact As the outer rail in a curve is situated higher in a curve due to canting, it is called the "high rail". The inner rail is lower than the outer rail and is therefore called the "low rail". The inside of the rail head facing the other rail is called the

Understanding Why, When and How Rail Grinding is Performed
• Key role of grinding is to control and remove rail surface defects – Grinding templates and patterns to address class of defects • NOT ALL DEFECTS HAVE TO BE COMPLETELY REMOVED • Important to know when to stop grinding – Do not want to grind away all of the work hardened rail head – Grinding on a regular cycle allows for long term defect control

what is the purpose of grinding machine for railways
A grinding train maintains the track and helps to increase the lifespan of the rail. These trains remove small layers of metal from the railhead, helping us to keep the track in good condition. Our new fleet was introduced in 2017 and offers increased metal removal due to more productive grinding at speeds of up to 15mph.
