Driving system for railroad vehicle

Abstract

Provided is a high mobility railroad vehicle system configured to reciprocally carry out a direct drive between a non-electrically driven section and an electrically driven section without installing new facilities such as oil supply equipment and without considering distinction between the non-electrically and electrically driven sections. A railroad vehicle system is provided with an overall control apparatus to respectively control an external electric power supply means, an internal electric power supply means, an electricity storage means, electric power conversion means and a motor driving means. The railroad vehicle system judges or previously notifies as to whether the present driving railroad section is the electrically driven section or non-electrically driven section in accordance with driving position information received from a position information generation means such as a ground facility on a railroad equipped outside of the vehicle and a global positioning system (GPS). The system cuts off from an external electric power source in the non-electrically driven section and carries out a smooth shifting control in order to connect to the external electric power source in the electrically driven section.
