Abstract
A dual tamper vehicle is provided. The dual tamper vehicle has a single articulated frame assembly having two sets of tampers. The articulated frame assembly is, essentially, a bifurcated vehicle having a forward, first vehicle and a trailing, second vehicle joined by a primary coupling having three axes of rotation. The primary coupling having three axes of rotation allows the two vehicles to roll, pitch, and yaw relative to each other thereby allowing the single, long rail bifurcated vehicle to travel over a railroad.
