AUTOMATIC SPEED CONTROL OF CUTS IN GRAVITY MARSHALLING YARDS OF SWISS FEDERAL RAILWAYS
The first part of the lecture deals with theory and general conception of humps. Means of speed control (master retarders, secondary retarders, car pushers) are shortly described as well as a deduction of necessary command algorithms (F*DELTV-method of master and secondary retarders, delayed switching-on of siding retarders, operation of car pushers in function of succession of cuts to achieve good spacing of cuts in the switching zone, optimal thread of cuts into the sidings and to keep clear the danger zone behind the siding retarder in due time). Repercussions on the equipment are mentioned (e.g. very short response time of master retarders, one-trolley car pushers etc.) The second part of the paper deals with the experimental installations built up to prove the validity of layout conceptions, theory, algorithms, and with the experiences made. These concern design shortcomings of the equipment used. The third part deals with yards under construction (e.g. Zurich-Limmattal) or planned (Biel, Olten), notably with the layout of humps, computer configuration, etc.)
