A wayside friction management system, and method for monitoring and controlling a wayside friction management system is described. The system comprises one or more wayside device for mounting with a track of a rail system. The wayside device comprises a delivery system connected to a reservoir comprising a friction control media, the delivery system for applying the friction control media from the reservoir to one or both rails of a track. The wayside device further comprises one or more data collection module located at or adjacent to the delivery system. The data collection module for collecting and transmitting data to a remote performance unit. The data may comprise performance information, track status information, information of an environment of the track, information of a train passing over the track, status of the one or more wayside device, or a combination thereof. The wayside device may comprise a power source operatively connected to one or more components of the wayside device.

1. A method of monitoring a wayside friction management system comprising, collecting data measured at one or more data collection module located at a lateral/vertical force measurement location, transmitting the data by radio frequency, cellular communications channels, or both, from the data collection module to a remote performance unit, and comparing the data with base line reference values stored on a database of the remote performance unit, the base line reference values comprising track maintenance conditions and known lateral force measurement patterns correlated with known maintenance conditions. 2. The method of claim 1, wherein the data measured at each of the one or more lateral/vertical force measurement location pertains to performance information of the track, information of the train, status information of the track, an environment of the track, a measurement of lateral/vertical force, incoming vertical load, locomotive position, temperature, precipitation, wind, vibration, train speed, a video, a photograph, a sound recording, automatic equipment identification, reservoir tank level, pump motor current, delivery line pressure, delivery line temperature, battery voltage, or a combination thereof. 3. The method of claim 2, wherein the data measured includes incoming vertical load and locomotive position data, analyzing the data to identify and categorize train type, loaded/empty status of the train to ensure that the data compared is obtained from like-traffic. 4. The method of claim 2, wherein the data measured is automatic equipment identification (AEI) data, comparing the AEI data with the lateral/vertical force records stored in the remote performance database to produce results, and using the results to identify specific traffic types by code. 5. The method of claim 4, wherein the data measured is speed data, filtering the data to exclude data from trains operating at speeds significantly below or above the normal distribution of speeds at each lateral/vertical force measurement location. 6. The method of claim 1, wherein the wayside friction management system comprises one or more wayside device, the data measured from one or more data collection module is compared with the base line reference values stored on a database of the remote performance unit, the base line reference values comprising track maintenance condition, intentional system shutdown conditions due to known track maintenance work, track grinding, tie removal, tie replacement, or a combination thereof, to determine whether an adjustment of a delivery system of the one or more wayside device is needed to restore target lateral force levels. 7. The method of claim 6, wherein changes in friction control system application settings are transmitted to the one or more wayside device. 8. The method of claim 7, wherein an increase in a lateral/vertical force ratio, or an average lateral axel force measurement obtained at the lateral/vertical force measurement location, when compared to a value predetermined at the lateral/vertical force measurement location, results in a change of a setting transmitted to the one or more wayside device to increase friction control media application to a track. 9. The method of claim 7, wherein no change of a lateral/vertical force ratio, or an average lateral axel force measurement obtained at the lateral/vertical force measurement location, when compared to a threshold value predetermined at the lateral/vertical force measurement location, results in no change to a setting of friction control media application transmitted to the one or more wayside device. 10. The method of claim 1, wherein the base line reference values further comprise recent values obtained from the lateral/vertical force measurement location stored on the database of the remote performance monitoring unit.
