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.
