1) A railgrinder is more likely to be a train, not a single vehicle. 2) "before they need to be replaced" is tautology. 3) "Many forms are known" is completely uninformative. 4) A simple angle grinder might be used for a localized touch-up but is unsuitable for reprofiling of continuous length of rail which is what a railgrinder usually does.

with rail grinding. Rail grinding is particularly hard, manual . work using a stone grinder in a half-crouched position. It takes approx. 60 minutes to weld single rail, so second welding can be done only for three sets of rails a day within usual track maintenance time. Improvement of work efficiency thus has been demanded. In the light of ...

Assuming that the rail profile can be accurately characterized by a continuous mathematical function (an assumption that becomes more questionable as the rail wears and assumes a non-uniform profile), then the effect of a single grinding stone can be calculated as a function of the grinding angle, as shown in Figure 3.

The modern rail grinder is a high-capacity, computer-controlled machine with the ability to grind at angles up to 70 degrees (in most cases) to the gauge side of the rail (see Figure 1). They are able to provide as much as 30 hp to each grinding motor and to apply various patterns to the rail by positioning the grinding motors at different angles.

By constantly moving back and forth while travelling slowly, at speeds of up to 8 km/h, precisely fine-tuned grinding is achieved in a single pass. Oscillating grinding is recommended especially for areas prone to developing rail defects. Examples include stations or stops where waves form or other "hotspots" where corrugations occur.
