GUIDELINES FOR ENHANCEMENT OF VISUAL CONSPICUITY OF THE TRAILING END OF TRAINS

The report summarizes a comprehensive study of potential means of reducing the probability of train-train collisions through enhancement of the visual conspicuity of the trailing end of trains. The basic function requirements and constraints for such devices are set forth, followed by a review of relevant past research. The form and parameter values of the warning system found to incorporate the best combinations of practicality and effectiveness are specified; in essence the system consists of clear xenon flash-tube beacons mounted on opposite sides of the car at the roofline, flashing simultaneously. Experimental use and observations of the system are described, and detailed recommendations are included.
