A railway gate system (10) comprises a railway station (14) having an elevated platform area (16), and a recessed area (20) provided with a track (22). A gate (28) has a restraining rail (30) and a plurality of cylindrical posts (34) secured thereto. The edge of the platform area (16) is provided with a horizontal recess (40) and vertical apertures (42) for receiving the rail (30) and the posts (34), respectively. Motion imparting mechanisms (46) for the gate (28) include assemblies of pistons (48) and cylinders (52) with the pistons (48) extending through the apertures (42) and secured to the rail (30) for moving the gate (28) between positions. The assemblies of pistons (48) and cylinders (52) are connected to a hydraulic power center (64). The gate system (10) further includes a pair of electric eyes (74, 76) located along the track for detecting approaching and departing of a rairoad car.
