In the project Application of the RCM methodology to the maintenance of the point machines in the West Light Rail Lines system, the RCM methodology was applied to a generic, universal point machine. The failure modes, causes and effects of the failures were analyzed by applying an FMEA (Failure Mode and Effects Analysis), in order to establish levels of critical importance and later to determine the causes and propose possible maintenance actions to be carried out. The project’s greatest achievement has been the preparation and application of an RCM analysis process to the West Light Rail Lines’s point machines, creating a new preventive maintenance program that adjusts the tasks and applicable frequencies according to the specific operating environment of each of the devices included.
