Document Type and Number:
Japanese Patent JPS5145846
Kind Code:
B2
Abstract:
A robot locomotive is disclosed which is adapted to be releasably coupled to a freight car which is approaching at a relatively lower speed to the head of a classifying network in a yard or which is stopped at the head so as to accelerate and push it off on a desired track. Upon a main frame supported by wheels riding on guide rails laid inside a railway track are mounted a hydraulically operated pusher assembly adapted to forcibly press against the flanges of the first wheel of a freight car and a hydraulic brake system. In response to the external signals an electronic controller controls various hydraulic control valves in a hydraulic controller so as to control the hydraulically operated pusher assembly and brake system.
