Abstract

Modelling and simulation of marshalling yard operation providing semi-continuous speed control R J Hill* & M Petkova* ^School of Electrical Engineering, University of Bath, UK ^T Kableshkov Higher School of Transport, Sofia, Bulgaria (at time of research) Abstract It is a well-known fact that for the last decade the railways in Eastern Europe suffered severe erosion. In the case of freight traffic the decline was made much worse by the closing of inefficient heavy industries which relied on rail to carry the bulk of their raw materials and products. Directive 91/440 of the European Union is designed to help railways attain as a key objective halt the loss of traffic by adopting market strategies. In line with it a study has been conducted to develop an optimal structure for automation of a marshalling yard taking into account specific factors, i.e. light duty, low humping velocity and relatively low cost, giving preference to automation with spot retarders. 1 Introduction
