ABSTRACT:
A process and apparatus for on-track truing of the surface of the head of rails of a railway wherein a predetermined number of truing tools, oriented along tangents to the profile of the head, are moved along generatrices of the surface and wherein the value of at least one of the parameters influencing the metal-removing capability of at least one truing tool is under the control of a control value which is preestablished as a function of the desired cutting depth of the tool. At least one magnitude value representative of the state of the rail head before truing is measured by a measuring device at the front of a truing vehicle and the control value is determined as a function of the measured value and of the known values corresponding to the metal-removing capability. The control value is adjusted according to the results obtained at the end of a rail length corresponding at least to the length of the entire assembly of truing tools utilized.
