Grind-Manage is a production rail grinding management tool that uses input profiles taken by optical rail profile measuring systems and calculates the production grinding requirements for a given territory or entire rail network. This includes grinding patterns, grinding speeds, and number of grinding passes required
Rail grinding trains restore the profile at about 20 miles per hour. A locomotive pulls the equipment with a few dozen electric motors with grinding stones set at different angles. Tank cars spray water in front of the grinders for lubrication, and behind the train to put out the inevitable fires. Living quarters for the crew are often included ...

MoW: Geometry & Rail Grinding Trains and Jointed Rail. Decades of research have been invested in determining a good shape for the surface of a railroad wheel and for the railhead. Wheel lathes are used to restore the desired shape of the wheels. Rail grinders are used to restore the desired shape of the rail head.
Grinding trains. 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.
• 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
Refining Approaches to Corrective and Preventive Rail Grinding. A Loram 8-stone LPC-Series transit grinder at work on the Skybridge, Vancouver, BC. Railroads and transit systems are adopting innovative approaches to improve efficiency and productivity. As service providers look to better define grind quality.
Rail corrugation is a common railway defect that involves diverse and complex factors. Rail grinding is also the most commonly used method to address corrugations. Through numerous irregularity tests and one-third octave frequency spectrum analyses, this study determined the characteristics and development process for rail corrugation on high-speed …
pre-grind, the Contactor shall provide an outlined preliminary grinding schedule indicating the location, anticipated number of passes and the preliminary patterns. 1.2 The Contractor shall provide production rail grinding using a rail bound vehicle, equipped with angle profile grinding techniques for both right and left rails.
Grinding and milling are essential to rail quality. 23 January 2009 | By James Abbott, Technical Editor, Global Railway Review. Rail grinding helps to prevent the dangerous build-up of rolling contact fatigue, and also reduces running noise for line side communities. James Abbott, Technical Editor for Global Railway Review, assesses some ...
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

Answer (1 of 3): A railway grinding machine falls in the category of track maintenance vehicles. With continuous operations of trains the rail needs maintenance to maintain the desired rail profile so as to obtain the optimum contact between the rails and wheels. Basically trains run on …
Rail corrugation measuring equipment and rail grinding trains RML supplies equipment that measures rail irregularities, in particular corrugation, from a vehicle. The rail corrugation analyser (RCA) is typically used on a reprofiling train to demonstrate compliance with standards such as EN13231-3, but versions have also been supplied for ...
Rail grinders will typically use a coarser stone to work out all of the dips and wear found along the rail head and a finer stone to finish the work and return the rail to a nice, polished finish. A crewman eyes the photographer as a Loram grinder rolls …
