Abstract
A railroad remote monitoring and detection system employing cameras, that may or may not be remotely positionable and repositionable, and other motion and presence detection devices such as millimeter wave radar and/or passive infrared and or ultrasound detectors. The use of multiple sensor devices reduces the occurrence of false alarms. The system employs software and logic to detect predetermined alarm conditions and then send a signal to a local or central command center and trains on the route. The system includes wireless receivers onboard the train that scan for monitor information one or more monitor stations in advance of the trains progress to give the train engineer/driver advanced warning of hazardous conditions on the trains route. Alarms to the central control center can be monitored to determine a recurrence of potentially hazardous conditions at a particular site so that steps can be taken to avoid such conditions in the future.
