Abstract
A safety monitoring system for a catenary system that includes an overhead wire, a support pole and a counterweight attached to the end of the overhead wire and suspended by the support pole. The catenary safety monitoring system includes a temperature sensor for detecting an ambient temperature, a position sensor for detecting a position of the counterweight and an electronic controller. The electronic controller compares a detected position of the counterweight with a predicted position determined by the electronic controller using an ambient temperature from the temperature sensor. A message transmitter provides a warning to a user if the detected position of counterweight is not within a predetermined percentage of the predicted position.
