1. A method for orienting rail tie plates to be distributed on or in close proximity to ties of a railroad track, wherein each of the rail tie plates has a gauge side end and a field side end and a pair of shoulders extending upward from and across a shoulder side surface of the rail tie plate transverse to a longitudinal axis of the rail tie plate, the method comprising the steps of:
singulating a plurality of randomly oriented rail tie plates into a conveyed stream of individual rail tie plates oriented longitudinally relative to a direction of conveyance and conveyed successively in the direction of conveyance including rail tie plates oriented right side up and rail tie plates oriented upside down;
conveying the rail tie plates successively through a tie plate flipping assembly flipping upside down rail tie plates into a right side up orientation while maintaining right side up rail tie plates in the right side up orientation; and
thereafter, scanning the right side up rail tie plates with a sensor in communication with a controller and, using the controller, determining a longitudinal orientation of each rail tie plate conveyed past the sensor relative to the direction of conveyance, and selectively rotating the rail tie plate a quarter turn.
