RAILROAD GRINDING MACHINE ABSTRACT A rail grinding machine especially designed for grinding railroad track rails at railroad track switches and road crossings. The grinding machine includes an articulated grinding module supporting undercarriage suspended from the grinding machine main frame. The undercarriage includes a unique suspension system that allows for lateral shifting and pivoting of the undercarriage independently of the grinding machine main frame. Grinding operations are controlled by sensing the supply pressure of the constant flow hydraulic fluid used to power the individual grinding modules, and positioning the grinding modules in grinding abutment with the rails as a function of the supply pressure.
