A University of Nottingham research programme on rail human factors, in collaboration with Network Rail, has delivered significant impact to practitioners and professional services within the industry. New tools for workload management and efficiency are now routinely used as part of Network Rail's ergonomics toolkit and are supporting the fulfilment of the company's National Operating Strategy. Risk analysis tools have also contributed to Network Rail's programme providing enhanced asset information.
These tools have also been taken up by international train operators in Australia and the Netherlands.
The UK Rail Industry has set itself a target of increasing capacity by a factor of two within 30 years for both passengers and freight. A central problem is to increase the capacity and performance of the (existing) rail network. Signalling systems and their safety is a major consideration. It is towards this long-term goal that we direct our research activity on signalling. Our research impacts both current practices and strategic planning within the Railway Industry:
The Railway Systems Group develops state-of-the-art condition monitoring and instrumentation systems that identify system faults before they degrade into failures that cause passenger disruption. The key impacts of the Railway Systems Group lie in the following areas:
Examples of direct quantifiable impact are a reduction of over 60,000 minutes in train delays over the last one year period through monitoring of 5,600 railway point machines (the cost to Network Rail of delays is between £20/min to £160/min). Also, the deployment of an award winning conductor shoe monitoring system, which has resulted in an estimated savings of 12,150 minutes. Expert advice and practical prototypes have been through active contracts from railway companies totalling £4.2M. This includes an influence in the £7 billion successful order from the Department for Transport to Hitachi for new trains, energy saving strategies reported by the Office of the Rail Regulator and evidence to the Transport Select Committee on winter operations. These have been achieved by working extensively with the British and international railway industries in the area of condition monitoring and bespoke instrumentation systems that support an improvement in the dependability of rail travel.
The School of Engineering at MMU has longstanding research into many aspects of railway engineering. This commenced in 1998 under the leadership of Professor Simon Iwnicki, who carried out research into the interaction between railway vehicles and the track. The understanding of the dynamics of the wheel rail contact that has resulted from this work has been developed into a number of tools and techniques that are being used on a daily basis by the rail industry both to design new railway systems and to predict the deterioration of railway wheels and rails. This allows railway engineers to predict and control roughness growth on rails and to optimise wheel profiles and maintenance intervals on wheel and track.
This work is now helping the railway industry internationally to realise both economic and environmental impacts as track maintenance costs are reduced, safety levels are enhanced and passengers continue to switch from road to rail in increasing numbers. This is evidenced by the award of new research contracts and industry funding and by direct input into industry standards.
The Confidential Incident Reporting and Analysis System (CIRAS), was developed in response to concerns about the role of human error in UK railway accidents. In 2008, CIRAS became an independently operated unit within the Rail Safety and Standards Board and is now available to everyone working in the UK rail industry; it codes reports about health and safety concerns and then facilitates a resolution between the individual and the relevant company or companies. 2.75 million passengers and 400,000 tonnes of freight use the railways in Great Britain every day and CIRAS impacts on the safety of all railway staff and passengers by ensuring that there are no barriers to reporting and resolving potential problems and hazards. It has also led to the construction of a database allowing safety issues to be classified and resolved before they can occur. Between 2008 and 2012 CIRAS received 2228 reports; 45% of these resulted in tangible safety improvements and approximately 33% contained important information about safety that was new to the company concerned. CIRAS has directly influenced the development of a confidential reporting system used in the USA.
This case study highlights the research at Plymouth University into the development of a specialist security thread in banknotes which has been commissioned and adopted by De La Rue, the world's largest commercial currency printer and papermaker. The system has provided quality assurance for over five billion banknotes, including the Euro, and improved the performance of a worldwide business through the introduction of new technology. Potential future losses through counterfeit have been mitigated by the improved quality assurance systems.
Led by Professor Andrews, a computational method for real time mission planning, based on Binary Decision Diagrams (BDD), was developed in the Mathematical Sciences Department at Loughborough University (LU) from 1993-2003. This is fast and accurate and can be used to support decision-making on system utilisation in real-time operation, which has led to the ability to diagnose in flight faults for unmanned aerial vehicle (UAV) applications.
The research has changed the understanding and awareness of the advantages of BDD, resulting in integration into major industrial trials and proprietary software products, including at BAE Systems, one of the world's largest companies in an area of vital importance to UK security and economic development. The methodology has attracted significant research funding in collaborative programmes with industry.
The Network & Information Security Technology Lab (NISTL) at Liverpool John Moores University (LJMU) conducts research in securing networked systems against the growing threat of cyber crime. The research has generated a correlated set of new security protocols, novel system composition methods and efficient digital forensic analysis schemes for more effective layered security protection. Their main impacts for the period 01/2008 - 07/2013 are highlighted below:
In addition to the above direct impacts, our work is also beneficial to other organisations and even the general public, as they all require security techniques for information protection.
Research in the Centre for Software Reliability (CSR) at City University London has made significant advances in ways to assess the safety and reliability of safety-critical, fault-tolerant software-based systems. This work supports quantitative safety cases and has influenced practice and regulation in UK and international industries. [text removed for publication] The work has had significant benefit for regulators and licensees of UK nuclear plant, has been recognised in the US nuclear industry and is additionally of benefit to the general public, in ensuring not only that reasoning about the safety of nuclear plant is rigorous and valid, but also that it is seen to be so in order that safety claims are widely and justifiably believed.
Reductions in railway infrastructure and operating costs, through efficiency gains, deliver benefits to taxpayers (via lower subsidies) and/or passengers (via lower fares). Research undertaken by the Institute for Transport Studies (ITS) at the University of Leeds from 2005 onwards revealed a 37% efficiency gap in relation to rail infrastructure costs and operations, relative to international best practice. The key impact of this research was to inform the Office of Rail Regulation's (ORR) setting, in 2008, of annual efficiency targets for Network Rail for the subsequent five-year period, resulting in a reduction in costs from £18.2bn to £15.8bn over the five year regulatory `control period' starting 2009/10. A secondary impact of the ITS Leeds research was to provide key benchmarking and evidence in more recent ORR efficiency assessments (2010) and Sir Roy McNulty's long-term policy-setting Rail Value for Money (VfM) study (2011). Extending the reach of these research impacts, the water and sewerage regulator OFWAT has, from 2013, adopted the ITS Leeds approach for its latest periodic review.
