Abstract (en)
A non trailable switch machine for railroad switches or the like, which switch machine comprises a trailing detecting sensor (11) for measuring at least one physical parameter describing the force exerted by an action on the switch machine and/or on the points (P1, P2) and or on a movable crossing point and means (24, 25, 31, 32, 41, 42) for reversibly or irreversibly preventing the operation of the switch machine depending on the values of the said measured al least one physical parameter. the switch machine is able to classify the trailing forces between "dangerous trailing forces" with potential damage to the turnout or its components (superstructure and switch system), and "non dangerous trailing forces". This classification permits to optimize expenses related to corrective maintenance after trailing events. A "non dangerous trailing" is detected trough a loss of detection of the turnout, but the customer operators are able to recover detection of the turnout from remote position without inspecting the turnout. A "dangerous trailing" is detected trough a loss of detection of the turnout, and the only way to recover detection of the turnout is to substitute the damaged parts.
