IMPROVEMENT WORK ON MAIN LINES IN RELATION TO TRAIN OPERATION AND LATE RUNNING

AUSBAU VON FERNSTRECKEN IN ABHAENGIGKEIT VOM BETRIEBSPROGRAMM UND VERSPAETUNGSNIVEAU

One of the central problems of railway operating sciences is the presentation of the theoretical relationships between system size, train-running schedule and the standard of timekeeping. In the present article a simulation model for main lines with high-speed traffic is put forward which can be used to determine qualitative line carrying capacity. Examples of its application show methods of formulating decision aids for track work and train operation. The starting point in each case is an uncontrolled operating condition in which, with respect to traffic hinderance, a natural equilibrium comes about between the train-running schedule and the state of route work, by way of which the compatibility of speed groups, mix ratios and traffic density can be made apparent. From this information it is possible to derive favourable intervals between passing places and also the number of passing tracks at each of them. Then the effects were tested of control algorithms which--starting from the natural equilibrium of uncontrolled operation-allow the operating quality with fast trains to be improved step by step until a hinderance-free condition is attained. With this simulation model, which exactly calculates a train's time-distance and speed-distance lines, the train-running schedule and the state of the route can be studied not only in normal working; also under extreme conditions the reaction of the latent forces in an operating system can be made evident.
