Abstract

Developing arrangements for "open access" to rail networks, together with the establishment of service reliability targets and penalty charges, requires a new understanding of both system capacity and the effect on reliability of additional services. The separation of trains on any one line depends upon an interaction between the traction, route alignment and signalling. The capacity of the whole system however, is also determined by junctions, and the structure of the intended timetable, reflecting commercial aspirations. However, the practical capacity limit must also take account of service reliability in the face inevitable disruptions. Service reliability is principally a function of intensity of operation, increasing the chance of "delay by reaction" as each late train potentially delays others. Conventional planning
