Publication number: 20150158511Abstract: 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.Type: ApplicationFiled: October 31, 2014Publication date: June 11, 2015Inventors: Jeffrey Michael Fries, Joseph Forrest Noffsinger, Richard Lee Lawson, Aric Albert Weingartner, Curtis Doyle Mechling, Aaron Richard Mitti, Martin Paget, William David Shields
