A railroad switch device for moving railroad switch points. The device includes a hydraulic unit having a hydraulic manifold coupled to a hydraulic pump integrated with an electric motor via a pressure pipe, where the hydraulic manifold is also coupled to the hydraulic pump via a hydraulic oil reservoir and a return pipe, and the hydraulic manifold is coupled to a hydraulic double-rod cylinder to provide forward movement and reverse movement of a point rod. Also included is a mechanical target to automatically indicate the position of a point rod, and a plurality of spring units to produce a continuous thrust force for holding the railroad switch points closed in forward position and reverse position, wherein the plurality of spring units control the target rotation to 90 degrees.
