ABSTRACT:
A method and device for facilitating the movement of a number of moving bodies such as trains travelling behind each other in a closed circuit with all the necessary automatic functions such as safety precautions against collision and control of traffic, is arranged by providing an ideal circulation of imaginary moving bodies corresponding to the actual bodies and progressing regularly according to a pre-established programme, each actual moving body being constrained to remain, within limits behind its corresponding imaginary moving body taking into account possible braking requirements, and, in front of the imaginary moving body controlling the next actual moving body. Means are provided for stopping the imaginary moving bodies and consequently the actual moving bodies in the case of mishaps, all the functions being effected with simple passive reference marks located along the line and spaced apart in such a way that the time taken by imaginary moving bodies to cover the distance separating two successive reference marks is always a substantially constant time.
