Abstract

Transmission-Based Signalling (TBS) Systems offer Metro administrations major operational benefits in terms of improved line capacities, improved traffic regulation and possible reductions in journey time. Other benefits include large reductions in track equipment and associated cabling, improved maintenance facilities and the capability to overlay onto existing Fixed Block installations. Whilst the steady-state headway-performance of Moving Block based TBS systems is well understood, the dynamics of train performance when signalling interaction occurs has received little attention. Here analytical studies are difficult because of the non- lineanties associated with both the safety algorithms and the control system The paper describes simulation models that identify the basic control pro
