The disclosed device provides improved hydraulic railroad switch points and presents a solution for avoiding the switch points from moving due to the spring force generated during manual installation or maintenance. The present device further provides a reliable point detection and indication mechanism. The device includes a trailable switching unit that enables a train to run through the trailable switching unit. A throw unit automatically adjusts plurality of rail and throw distances. The hydraulic cylinder provides constant forward and reverse movements, each movement in time defining an operation period. The hydraulic circuit unit increases the operation period. The center stroke unit blocks the hydraulic cylinder movement at the middle stroke during installation and maintenance. The mechanical target automatically indicates the position of a point rod. The spring unit produces the continuous thrust force that keeps the railroad switch points closed in forward and reverse positions. The proximity sensors detect the point rod position and adjust the point rod.
