Abstract
An automated trackside railed car discharge gate operating system is disclosed which can automatically unload a string of cars “on the fly” and without the need for a separate indexing system. The system includes a pair of carriage-mounted tool systems for opening/closing capstan-operated railcar gates disposed to travel along a carriage track and including visual devices that acquire and track capstans and coordinate tool orientation and operation.
