A method and apparatus for spreading ballast along railways makes use of an inertial measurement system to determine where to apply ballast from a hopper car. A variety of techniques can be used to determine the location and speed of the ballast spreading train, including manual or automated visual techniques, laser technology, radar technology, radio frequency transponders, magnetic sensor, thermal imaging and aerial photogrammetry. The invention also contemplates "on the fly" surveys and terrain profiling using lasers or radar.

L'invention concerne un procédé et un appareil permettant d'étaler un ballast sur une voie ferrée, qui utilise un système de mesure inertiel afin de déterminer l'emplacement où appliquer ledit ballast à partir d'un wagon-trémie. On peut utiliser une variété de techniques pour déterminer l'emplacement et la vitesse d'étalement du train de ballast, notamment des techniques manuelles ou des techniques visuelles automatiques, une technologie laser, une technologie radar, des transpondeurs, un capteur magnétique, l'imagerie thermique et la photogrammétrie aérienne. L'invention concerne également des études à la volée et un profilage de terrain à l'aide de lasers ou de radars.
