Abstract (en)

[origin: WO9955571A1] An actuator for a railway rail switch system comprising stock rails (10, 12) and switch rails (16, 18) includes an actuator carriage moveable on a base (20). The carriage is mounted to the switch rails (16, 18) via brackets (72) and is driven relative to the base (20) such that the carriage first moves relative to the brackets to locate a stock rail, and when the stock rail is engaged the brackets move relative to the carriage to align the switch rails to the stock rail. As a result secure clamping is achieved between the switch and stock rails and there is automatic compensation for movement or wear in the rails.
