CBTC (Communication Based Train Control) systems are known as comprehensive, integrated and intelligent control systems for rail systems including mainline railways, light rails and underground lines in cities. With the development of modern data communication, computer and control techniques, CBTC represents the future direction of rail control systems. At present, CBTC has been used in light ...

Abstract Train-to-wayside (T2W) and train-to-train (T2T) communication modes may coexist in future train-centric communication-based train control (CBTC) systems. The feasibility of T2T urban rail transit is analyzed first. Referring to the device-to-device (D2D) scenario general cellular network, this paper establishes a radio resource optimization model for coexistence train-to-wayside commun...

The paper investigates train scheduling problems when prioritised trains and non-prioritised trains are simultaneously traversed in a single-line rail network. In this case, no-wait conditions arise because the prioritised trains such as express passenger trains should traverse continuously without any interruption. In comparison, non-prioritised trains such as freight trains are allowed to ent...

The privatisation of British Rail into twenty-five train operating companies and three freight companies has highlighted the need for each company to have efficient operating schedules. Manpower costs are a significant element in any transport organisation and the ability to minimise these costs is seen as crucial to the well running of these companies. In addition the need to try out different...

Transshipment yards, where gantry cranes allow for an e cient transshipment of containers between di erent freight trains, are important entities in modern railway systems and facilitate the general shift from point-to-point transport to hub-and-spoke railway systems. Modern rail-rail transshipment yards accelerate container handling, so that multiple smaller trains with equal destination can b...

Safety is a high priority for any rail system, and there are several safety concerns associated with operating passenger and freight trains on shared-use rail corridors. Adjacent track accident (ATA) is one of the most important concerns. ATA refers to train accident scenarios where a derailed equipment intrudes adjacent tracks, causing operation disturbance and potential subsequent train colli...

With reduced environmental impact becoming an increasingly important benefit of the rail transportation mode, continual improvement in efficiency and reduced energy consumption has become a major concern to rail transit operators. For electrified rail transit operations, regenerative braking is one practical way for saving energy because it enables the kinetic energy of a train to be transmitte...

In heavy traffic nodes of rail networks, as in main stations, conflicts and subsequent train delays greatly propagate during operations. A disturbance which is at origin only a few seconds long can quickly lead to other delays of over five minutes. To limit this phenomenon, newmethods andmodels are necessary to optimise the use of scarce resources like platforms and track sections. The operator...

The study results reported here are part of a larger research project that developed a manual for practitioners to improve safety at rail transit platform/train and platform/guideway interfaces. As part of that effort, passenger injury incident data was collected from five rail transit systems, and interviews were conducted with safety officers at other rail transit systems in the US and Canada...
