There is a need to improve the maintenance of electric switch machine in particular the locking mechanism, which needs precise adjustment to within 0.1 mm. The position of the lock rod deviates slightly with each switching motion, making it difficult to monitor the status of the lock adjustment. A new monitoring system, developed for electric switch machine, is capable of adjusting the lock more accurately. Furthermore, the system enables providing information on the dynamic characteristics of the switch upon train passage.
