    Railtrack intends to undertake deployment of a state-of-the-art radio system, on a national basis, to support Railtrack's operations well into the 21st. century. A digital radio system is to be deployed in order to meet this aim, replacing the existing analogue networks. DART (Digital Advanced Radio for Trains) is the name given to the radio system to be deployed. The DART project is to develop a single radio system based on a public GSM network which will allow secure communication of both voice and data between train drivers and signallers, zone controllers and other DART users View full abstract»

  • Broadband transmission for railways

    The introduction of transmission systems based on the synchronous digital hierarchy (SDH) has created new opportunities for flexible and resilient transmission networks. This paper looks at reasons to deploy SDH in railway networks, and reviews some of the design considerations. The complementary technologies of WDM, ATM and flexible multiplexers are also introduced. Some of the new services which will become available once broadband capacity can be provisioned from the network to stations, control centres and the railway lineside are described View full abstract»

  • London Underground platform to train CCTV studies

    When one person (train) operation was introduced it was necessary to install equipment within the confines of tunnels, platforms and trackside and indeed within the rolling stock itself, to provide a method of safe operation at the platform to train interface. This has and still does present major challenges associated with the wide range and diversity of platforms and structures on the underground. The paper gives a historical and in depth view of how these problems have been overcome and the issues associated with providing CCTV to ensure a safe transition at the platform to train interface. In particular it focuses on the platform to train CCTV study and demonstrate how continuous improvements have been applied to each successive system View full abstract»

  • London Underground's Connect Project

    London Underground is currently procuring via the UK government's Private Finance Initiative (PFI) the replacement of its existing train, station and depot radio systems with a single trunked private mobile radio system and the installation of a new fibre optic transmission network which will support services such as telephony, customer/staff information systems and IT as well as a video transmission network with capability to serve all operational sites. The main drivers for the Project are due firstly to the fact that many of the existing radio and transmission systems are beginning to reach the end of their useful lives and require replacement. Secondly the existing systems no longer provide the functionality and types of service required for a modern mass transit railway serving a large urban area such as London. The Connect Project aims to provide a fully integrated communications system which will serve London Underground well into the 21st century and support new types of services and more efficient ways of working which will bring benefits to both the customers and staff of London Underground. This paper gives an overview of the history of the project, the government's PFI and how it relates to London Underground's Connect Project, the procurement process and a description of the likely technologies and their deployment View full abstract»

    The Docklands Light Railway (DLR) is a light rail rapid passenger transit system which serves the needs of residents and businesses within the London Docklands regeneration zone. DLR has a policy on noise which states the intentions of the company for the system-wide control of noise arising from train operations and sets down target maximum noise levels at adjacent buildings. In locations where the target levels are exceeded, DLR is committed to using best practicable means to minimise the levels of exterior noise at source. The “Smartsound” noise adaptive public address (PA) control system was first developed out of a need to resolve specific problems connected either with the inadequate transmission of announcements to passengers on stations during periods of intrusive background noise, or with unwanted overspill of the PA sound into neighbouring properties. The success of “Smartsound” has resulted in the development of a new control of environmental noise pollution whilst enabling the railway to maintain not only good communication with its passengers but also enhancement of customer safety and assurance through intelligible announcements when it matters most View full abstract»
