摘要

Methods and apparatus for implementing ballast to a bed of a railroad track and to supervise a bed of a railroad, a method and apparatus for spreading ballast along railways makes use of an inertial measurement system to determine where to apply for a ballast hopper car.A variety of techniques can be used to determine the location and speed of the train ballast spreader, including visual techniques manual or automated, laser technology, radar technology, transpondores RF, magnetic sensor, thermal imaging, and Aerofotogrametria.The invention also includes surveys "in motion" and leveling of ground using lasers or radar.
