Abstract. The paper is devoted to mining rail vehicle motion stability while motion on the rail track of steady and transient curvature. Several kinematical schemes of mining locomotives are studied. Assumed, that the most dynamically stable is locomotive with pin-joint coupling design. In addition, additional local movability of wheel set is studied subject to safety factor while motion on the mining rail track.

Keywords: mining locomotive, kinematics, safety factor.
