From the 1830s to today, the railroad industry has developed myriad complex mechanisms to help keep North America’s railroad rights-of-ways safe, efficient, and relatively accident-free. In this paperback rerelease of the successful 2003 title, the otherwise-arcane world of railroad signaling is explained in concise language and brought to life with nearly 200 fantastic photographs that depict signaling history and all aspects of modern operations. Author and photographer Brian Solomon brings his wealth of knowledge and photographic talent to a subject that has not often been tackled in book form, yet is integral to the American railroad experience.

Complexity in automation- and safety systems in railway as well as automotive applications are dominated more and more by formal description means, methods and tools. Formal techniques provide next to correctness and integrity checkups – especially for safety relevant systems – the possibility to model, prove, simulate and check the specification of the system as well as to generate the system implementations. Requirements of the CENELEC- and IEC-Standards on formal techniques, particularly with regard to the handling of safety analysis, are to be treated in FORMS/FORMAT 2010. The main focus lies on topics facing formal techniques for railway applications and intelligent transportation systems as well as for automotive applications. Gained findings, experiences and also difficulties associated with the handling of the subject matter as well as description means and tools are to be shown.

TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.

This book examines the problem of interoperability related to operating rules and gives an overview of the formal method approaches related to this subject. The book examines the interoperability issues concerning implementation of European Rail Traffic Management System (ERTMS) while crossing a boarder. It also looks at the implementing of the ERTMS and provides solutions regarding operating rules for ERTMS lines, using formal methods and simulation tools. The contributors will also discuss operating rule validation and formal methods for safety assessment.

This NAO report examines how effectively the Strategic Rail Authority/Department for Transport and Network Rail turned around the West Coast programme between 2002 and 2006 in terms of delivering outputs and expected outcomes in line with the schedule and targets set by the government and set out in the West Coast Main Line Strategy of June 2003. Three areas were examined in detail: how the Strategic Rail Authority/Department of Transport and Network Rail addressed the weaknesses in programme management before 2002 to achieve delivery to schedule; whether costs have been brought under control; whether the programme is delivering its anticipated benefits. A number of findings and conclusions have been set out, including: that the SRA and Network Rail did turn around the programme through an industry-supported strategy, reducing technology risk through reliance on conventional signalling for most of the upgrade; there were some implementation problems in two areas, axle counters and computer-based interlocking signalling, which resulted in an increase in costs; in general, Network Rail's control of costs has improved, but an analysis of its reported and forecast expenditure shows a final programme spend of £8.6 billion, with an overspend of around £300 million; for renewal work on the west coast route, Network Rail is within its overall funding allowance and on course to achieve 70% of the £940 million cost efficiencies assumed by the rail Regulator; at present the Strategic Rail Authority provides subsidies on an annual basis to Virgin West Coast of £590 million in 2005-06 period, this amount represents a payment needed to maintain train services and is outside the £8.6 billion; the project has delivered journey time improvements, with punctuality and train reliability on the West Coast having improved since 2005; in the 2005-06 period, passenger journeys on Virgin West Coast grew by over 20%, and the remaining work on the programme to 2009 will increase passenger train and freight capacity, but the consensus in the rail industry is that around 2015 to 2020, the line will have insufficient capacity to sustain current levels of growth in passenger and freight traffic; the overall strategy has delivered passenger benefits from a modernised track, but value for money for the programme has not been maximised. The report sets out a number of recommendations, including: that the Department in future should model and appraise costs and benefits for different options for the timing of delivery of the project; that the Department and the Office of Rail Regulation should further develop standard definitions for costs for different stages and elements of transport projects; where projects propose new technology at significant cost, the Department and ORR should ensure that Network Rail draws up a supporting business case, addressing costs, benefits and possible challenges along with a supporting implementation and maintenance strategy; the ORR should ensure Network Rail progresses its plans and adopts best practice strategy, and this approach should include a company-wide strategy that addresses whole life costs in its investment appraisal/project business cases, along with improved recording of maintenance and renewals costs for its equipment.

Microprocessor controlled railway signaling or commonly termed Electronic Interlocking is in operation from the late 1980s on the World Railways and introduced in India in the 1990s.It has replaced older relay based and electro-mechanical systems in phases. As software is present extensively in such systems, safety is of prime concern to the users, in addition to the requirements of reliability. Methods of ensuring safety and preventing hazards have been covered extensively in the book. -Details of all the types of Electronic Interlocking systems installed on Indian Railways are illustrated. -The advantage of a single processor with concurrent error detection compared to two out of two and two out of three modular systems in the matter of reliability, safety and economy has been discussed. -Some methods of hazard analysis relevant to electronic systems have been dealt, with suggestions for improvement of components for safety and reliability. -Verification of hardware and software with computer aided methods along with simulation has been described. -Formal verification of railway interlocking with the application of theoretical computer science and software tools has been explained. -Application of systems engineering to the operation and maintenance of electronic interlocking system for enhancing safety is covered in a separate chapter.
