ABSTRACT:
An operating device for railroad switches, particularly for high-speed lines. To permit more stable positioning of the blades (A1,A2) and of the frog (C) of the switch, which in high-speed lines are of considerable length, in addition to the switching actuator (1) at the toes of the blades (A1,A2) and to that (3) of the frog (C), there are distributed along the blades (A1,A2) and along the frog (C) one or more further switching actuators (2,3'). The switching actuators (1,2) of the blades (A1,A2) and the switching actuators (3,3') of the frog (C) are of the hydraulic type and are controlled respectively by a hydraulic control unit (4,4').
