1. A system for detecting an object or abnormality on or near a rail track, the system comprising:
- scanning means for scanning on and near a portion of the rail track; and
detection means for determining the presence and location of the object or abnormality on or near the portion of the rail track based on information from the scanning means, andone or more image devices for capturing continuous images of track with date/time stamp, latitude and longitude positioning, milestones, vehicle speed, and other parameters for easy retrieval and verification, the images being stitched together to enable a decision-maker to review images.

17. A method of detecting an object or abnormality on or near a rail track, the method, comprising:
-
scanning on and near a portion of the rail track utilizing a scanning device; determining the presence and location of the object or abnormality on or near the portion of the rail track based on information from the scanning step utilizing a detection device coupled to the scanning device, and providing one or more image devices for capturing continuous images of track with date/time stamp, latitude and longitude positioning, milestones, vehicle speed, and other parameters for easy retrieval and verification, the images being stitched together to enable a decision-maker to review images.

18. A system for detecting an object or abnormality on or near a rail track, the system comprising:
-
scanning means for scanning on and near a portion of the rail track; detection means for determining the presence and location of the object or abnormality on or near the portion of the rail track based on information from the scanning means, and one or more image devices for capturing continuous images of track with date/time stamp, latitude and longitude positioning, milestones, vehicle speed, and other parameters for easy retrieval and verification, the images being stitched together to enable a decision-maker to review images, wherein the system is operable to reduce false alarms due to normal foreign objects by making use of visual attributes of the object, wherein the visual attributes of the object comprise one or more of a group consisting of size, perimeter, area, profile, luminous intensity and color.
