Abstract:

The study focused on a detailed investigation of all potential train detection techniques which do not use the track.  Both point sensing and continuous sensing system approaches were analyzed.  It was found that the transmission line sensor and magnetic point sensor offer the greatest likelihood of yielding a practical off-track detection system.  A comprehensive system analysis and evaluation of these concepts is made.  The study included a limited field test of the transmission line concept, which was then selected as the most promising for follow-on development.
