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 rail tracks.

Non-uniform rational B-spline (NURBS) curves are combined with the Kriging model to present a prediction method of the rail grinding profile for a grinding train. As a worn rail profile is a free-form curve, the parameterized model of a rail profile is constructed by using the cubic NURBS curve. Taking the removed area of the rail profile cross-section by grinding as the calculation index of ...

The paint was was new-looking, unlike the lime, yellow, and rust with intertwined B&M logo front-end loader that wintered at CPf-335.
Rail grinding has widely been used in railways and has been involved in many studies in recent decades. Previous research in the field of rail grinding has mainly focused on the design of rail grinding patterns [1,4], the design of grinding rail profiles [5,6], temperature fields in the rail grinding process [7,8] and grinding train dynamics [9 ...
Number 29 (original number unknown) was built by American Car Co. in 1896 or 1897 for the Canal & Claiborne Railroad Co. It is one of the first to bear the design made famous by Ford, Bacon & Davis (FB&D). By the 1930s, New Orleans Public Service Inc. converted the streetcar to a rail grinder.

The Concept of Rail Grinding was originated in 1930s for removal of rail surface defects. First production grinder was built in 1954 by Frank Speno Railroad Ballast Cleaning Co. It was a 9 car train with 96 grinding motors (7.5 hp each) working at 3 kmph. Later Speno International and Loram Maintenance of Way built many different types of

An analytical introduction to rail grinding was presented in this paper where a newly-designed profile serves as the targeted ground profile to extend the rail's service life. A method for determining eliminated metal due to rail grinding is established as an initial consideration in the process of rail profile correction. The analytical model of material removal contains grinding wheel ...

A railgrinder (or rail grinder) is a maintenance of way vehicle or train used to restore the profile and remove irregularities from worn tracks to extend its life and to improve the ride of trains using the track. Rail grinders were developed to increase the lifespan of the tracks being serviced for rail corrugation. Rail grinding is a process that is done to stop the deformation due to use ...
