The design, construction, operation and maintenance of rail network infrastructure has to be safe, reliable, supportive of customer needs, cost-effective and sustainable. Furthermore, to deliver the benefits of market opening and interoperability and to reduce the life-cycle costs of rolling stock and on-board signalling systems, there needs to be a (gradual) elimination of network diversity through a migration towards a common high-performing infrastructure system architecture.
A significant part of these costs is related to labour-intensive maintenance, most of which is preventive, although ad hoc interventions are also needed when faults occur — and these can be particularly costly and disruptive. Taking into account the ageing of existing infrastructure and the expected growth in passenger and freight volumes (+ 34 % and + 40 % in 2030 respectively, compared to a 2005 baseline), shorter infrastructure access times, maintenance needs and costs are likely to increase significantly in the coming years. Therefore, Shift2Rail must first and foremost focus on activities to support the reduction of these maintenance costs (such as simplified procedures or automation), and on solutions that can be rapidly and efficiently deployed.
At the same time, many parts of existing railway infrastructure (railway lines, stations and terminals) are nearing maximum capacity or are incapable of offering users and customers the level of service they demand. There is thus a need for a step change in the productivity of infrastructure assets. These will have to be managed in a more holistic and intelligent way, using lean operational practices and smart technologies that can ultimately help improve the reliability and responsiveness of customer service, as well as the capacity and overall economics of rail transportation.
Lastly, in order to support vital pan-European rail corridors and co-modal links, and offer a smart and competitive alternative to short and medium-distance flights and water and road-borne freight flows, rail infrastructure must ensure compatibility between infrastructures (interoperable and standardised infrastructure), as well as with other modes (intermodal infrastructure, including stations and passenger and freight hubs).
Work in IP3 will be organised around the following Technical Demonstrators (TDs) covering all R&I areas indicated in the Shift2Rail Master Plan: Enhanced Switch & Crossing System, Next-Generation Switch & Crossing System, Optimised Track System, Next Generation Track System, Proactive Bridge and Tunnel Assessment, Repair and Upgrade, Dynamic Railway Information Management System, Railway Integrated Measuring and Monitoring System, Intelligent Asset Management Strategies, Smart Power Supply, Smart Metering for Railway Distributed Energy Resource Management System and Future Stations.
The main objective of the ‘Enhanced Switch & Crossing System’ (TD 3.1) is to improve the operational performance of existing Switch & Crossing (S&C) designs through the delivery of new S&C subsystems with enhanced reliability, availability, maintainability and safety (RAMS), life-cycle costs (LCCs), sensing and monitoring capabilities, self-adjustment, noise and vibration performance, interoperability and modularity.
The ‘Next Generation Switch & Crossing System’ (TD 3.2) aims to provide radical, novel system solutions that deliver new methods for directing trains to change tracks with the aim of increasing capacity, while reducing maintenance needs, traffic disturbances and LCCs.
The ‘Optimised Track System’ (TD 3.3) will challenge track construction assumptions currently implicit in track design, and will explore how innovative solutions in the form of products, processes and procedures can provide higher levels of reliability, sustainability, capacity and LCC savings. The aim is to derive medium-term solutions, which calls for the solutions to be harmonised with current solutions and regulations.
The ‘Next-Generation Track System’ (TD 3.4) aims to drastically improve the track system, targeting a time range some 40 years beyond the present state of the art. This implies that step changes in performance are to be highly prioritised. The TD process will follow a tightly integrated chain, setting out by initially identifying the long-term needs of the railway and the potential solutions for meeting these.
The main objective of the ‘Proactive Bridge and Tunnel Assessment, Repair and Upgrade’ (TD 3.5) is to improve inspection methods and repair techniques to reduce costs, improve quality and extend their service life, if possible. Moreover, the reduction of noise and vibrations are prioritised objectives.
The ‘Dynamic Railway Information Management System (DRIMS)’ (TD 3.6) aims to define an innovative system for the management, processing and analysis of railway data. The activities in this TD will be strongly linked with the other two TDs in the area of information capturing and management. DRIMS is intended to collect information from the Railway Integrated Measuring and Monitoring System (RIMMS – TD 3.7) and to provide high-quality input to the Intelligent Asset Management Strategies (IAMS – TD 3.8).
The ‘Railway Integrated Measuring and Monitoring System (RIMMS)’ (TD 3.7) is to provide innovative tools and techniques for capturing information on the current status of assets, in a non-intrusive and fully integrated manner. To this end, the TD will focus on asset status data collection in close interaction with TD3.1 through TD3.5.
The vision of the ‘Intelligent Asset Management Strategies (IAMS)’ (TD 3.8) is a holistic, whole-system approach of asset management employing collected and processed data provided by TD3.6 and TD3.7. This includes putting long-term strategies in the context of day-to-day execution of the maintenance and other maintenance activities.
The wider objective of the ‘Smart Power Supply’ (TD 3.9) is to develop a railway power grid in an overall interconnected and communicating system.
The objective of the ‘Smart Metering for Railway Distributed Energy Resource Management System’ (TD 3.10) is to achieve a fine mapping of energy flows within the entire railway system, as the basis of any energy management strategy.
The primary objective of the ‘Future Stations’ (TD 3.11) is the provision of improved customer experience at stations. The TD is organised around four identified key functional demands: two demands relate to improving capacity and security in large stations, one demand relates to the design of small stations with the objective of reducing whole life costs and standardising design, where possible, and the final demand relates to accessibility.
The 11 TDs are strongly interrelated and they are clustered together into Integrated Technology Demonstrators (ITDs).
