Grinding and Milling are Essential for Rail Quality

Jan 23, 2009· After intensive in-track testing with a prototype device, six Speno grinding machines have been fitted with the company’s ‘Headcheck Grinding Scanner’. The system allows operators to check the reduction of fatigue defects during each grinding pass and to document the achieved result with respect to metal removal of the fatigued rail surface.

Rail grinding is a process that is usually performed by railbound machines. These machines remove metal from the rail using rotating grinding wheels (stones). The volume of metal removed is dependent upon the number and arrangement of stones on each rail,

Rail Grinding | Loram

Rail grinding is the cornerstone of virtually every railroad maintenance program. To maximize the life and value of rail assets, precision removal of fatigued metal, restoration of the rail head profile and removal of rail defects are the optimization goals of an effective rail grinding program.

Railgrinder Wikipedia

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

Rail Grinder in HO---ideas and opinions

Rather than really trying to grind the rail, I think I would use some steel such as the light bars on an Athearn loco against some stones for the lighting effects. Sort of like those old lithograph toys from Japan. The spark baffles on the prototype will cover most of the detail yet allow the fireworks to show through. Keep us informed.
