Abstract: A method for predicting failure of a crossing warning system is disclosed. The method includes monitoring an electrical characteristic of a first route when an electric current is injected into the first route. The first route has a crossing intersection with a second route and a crossing signal at the crossing intersection. The electrical characteristic is monitored to detect when a vehicle is approaching the crossing intersection on the first route and to determine when to activate the crossing signal at the crossing intersection. The method also includes identifying one or more changes in the electrical characteristic of the first route, and, based on the one or more changes that are identified, predicting a failure mode of the first route that interferes with detection of the vehicle approaching the crossing intersection.

Abstract: A monitoring method and system monitor a transmitted current that is injected into conductive components of a route traveled by vehicle systems, monitor a received current that represents a portion of the transmitted current that is conducted through the conductive components of the route, examine changes in the transmitted and/or received current over time to determine when the vehicle systems are on the route between a first location where the transmitted current is injected into the conductive components and a second location where the received current is monitored, and examine the changes in the transmitted and/or received currents. The changes are examined to identify (a) a contaminated portion of a surface on which the route is disposed, (b) a foreign object other than the vehicle systems that is contacting the route, and/or (c) a damaged or broken portion of at least one of the conductive components of the route.

Abstract: A method and system for monitoring a points machine obtains operating characteristics of the points machine that are representative of operations of the points machine during a movement event of rails at a switch. A waveform of the operating characteristics is examined to at least one of identify or predict a problem with the operations of the points machine. The waveform is examined by comparing the operating characteristics during the first movement event with at least one of: the operating characteristics obtained during a previous movement event; an expected value of the operating characteristics; or an expected duration of a moving time period during which the first rail is expected to move from or to an unlocked position.
