Abstract

Most of existing automation, signalling and telecommunications systems in EC accession states are worn enough and require renovations. In accordance with Technical Specifications for Interoperability, migration from class B control, command and signalling systems to class A is foreseen. Throughput capacity is considered to be one of the most important operational characteristics. Though infrastructure (especially in the 1520mm gauge countries) is quite similar, there exist many different approaches for increasing throughput capacity. The aim of this work was to find out the interdependence between speed of train and a throughput capacity for lines with implemented dynamic block sections, and to compare it with characteristic interdependence of a line with automatic block system; and also, to decide about the optimal train speed for reaching maximum throughput capacity. This paper describes in details calculation of train braking distance, speed and influencing forces for conventional lines with automatic block systems and for lines with dynamic block sections, as it considerably influences the throughput capacity. It is shown, that a greater throughput capacity can be reached if dynamic block sections are implemented. Throughput capacity in the case of dynamic block sections is not a monotonically rising speed function; not like for automatic block systems. Throughput capacity has extreme point. From this extreme point the train speed can be determined, under which the best value of a throughput capacity can be reached.
