A trolley auto-guided steering is provided to maintain pantographs centered under the power lines, allowing it to achieve higher speeds on grade and reduce wear on a pantograph shoe and/or a carbon brush by moving the contact area within the acceptable constraint limits. The pantograph includes a linkage configured to be mounted to the vehicle and movable relative to the vehicle between a stowed position and a deployed position. A current-collecting rail is supported by the linkage. A sensor assembly is mounted to the pantograph assembly and configured to detect a distance from the overhead wire. Data from the sensor assembly allows for continuous dynamic variable steering toward an aim point determined based on vehicle speed. This helps maintain the work vehicle's position underneath the overhead trolley lines and reduces operator fatigue.
