It combines high-speed hydromechanical transmission for transfer with hydrostatic low-constant-speed transmission for controlled grinding passes.<\/p>\n<p>The train carries rail-profile and corrugation measurement equipment so operators can plan grinding patterns and verify the longitudinal result. Published engineering literature describes one power car and six grinding cars, 96 individually angle- and pressure-adjustable grinding wheels, and 99 grinding modes.<\/p>\n<p class=\"rgw-note\"><strong>Direct answer:<\/strong> the CRRC GMC-96B is a 145 m, seven-car, 96-head grinding train that works in both directions at 3\u201315 km\/h. It is designed for periodic and corrective rail reprofiling, not switch-only or hand-guided grinding.<\/p>\n<p class=\"rgw-note\"><strong>Entity clarification:<\/strong> this page covers the CRRC-produced GMC-96B. It is not the GMC-96X model catalogued under GEMAC.
