Abstract
A method for detecting precipitation is disclosed. The method may include receiving a signal from a sensing module positioned in the vicinity of a railroad track, the signal being indicative of a capacitive dielectric property of a form of precipitation that has accumulated in the vicinity of the railroad track. The method may further include processing the signal from the sensing module to determine the type of precipitation that has accumulated in the vicinity of the railroad track as a function of the indicated capacitive dielectric property. The method may still further include sending a signal indicative of a recommended action based on the type of precipitation.
