Abstract

The system comprises a track profile database stored in a memory that has data relative to the identity of one or more wayside devices for a track and data relative to a location associated with each of the one or more wayside devices on the track. A camera generates visible spectral data of the wayside equipment as the vehicle travels on the track. A data storage device is provided for storing the spectral data received from the camera and data relative to a location of the powered vehicle when the camera generates the spectral data of the wayside equipment wherein the location of the powered vehicle represents the location of the wayside equipment. A controller is configured to compare the location data of the wayside equipment in the database to the location data associated with the spectral data of the wayside equipment stored in the data storage device.
