BACKGROUND In 2010, the "Tackling Suicide on the Railways" programme was launched as a joint initiative among Network Rail, the Samaritans and other key organisations such as the British Transport Police and train operators to achieve a 20% reduction in railway suicides from 2010 to 2015 in Great Britain. We report the most recent age and sex specific trends in railway suicide in England and Wa...

We consider how to improve railway timetables. As case we take the Rompnet of the dutch railways, a highly constrained problem, containing both hard and soft constraints. We show how to cast the constraints into the format of the Genocop system. Every train should run every hour at the same time and hence the constraints should be interpreted modulo sixty. This gives a non-convex search space o...

Signalling, a complex system is one of the most important infrastructures of railway service. The performance of railway signalling system depends on the functioning of a number of subsystems, such as panel, cable, relay, point and point machine, trackcircuit, signal, back indication, point-drive card, signal-drive card, and level crossing gate. Railway signalling system plays an important role...

Recently, the railway system is advancing to be intelligent according to the development of computer technology, and especially, many functions of train control system which are cores to the railway system are being operated by the software. Accordingly, the source code testing to validate safety of the railway train control system software becomes to be more important, and related internationa...

This study describes results of a household survey conducted in Eshane in the rural Kwazulu-Natal Midlands in April 2002, including baseline sociodemographic, energy usage, paraffin-related injury and safety knowledge information. A total of 404 interviews were conducted in five villages that fell within a 10-kilometre radius of the proposed Eshane integrated Energy Centre. Paraffin usage was h...

A protection scheme is proposed for the 3 kV DC railway, in Kwa-Zulu Natal province, a region with high lightning occurrence density. The surge was sought by implementing three metal-oxide arresters and an overhead ground wire. purpose of these determined their location circuit points that are vulnerable to adverse effects: arrester installed protect insulators between lines supporting metallic...

BACKGROUND Streetcar or train tracks in urban areas are difficult for bicyclists to negotiate and are a cause of crashes and injuries. This study used mixed methods to identify measures to prevent such crashes, by examining track-related crashes that resulted in injuries to cyclists, and obtaining information from the local transit agency and bike shops. METHODS We compared personal, trip, an...

In today’s business world whose characteristics include limited financial resources it is critical to identify and monitor where and how these resources need to be invested in the company. The Master Budget represents a plan of action which specifies how financial resources will be acquired and invested during a particular time period. Activity-Based Budgeting (ABB) is a budgeting approach that...

Most railway accidents happen at railway crossings. Therefore, how to detect humans or objects present in the risk area of a railway crossing and thus prevent accidents are important tasks. In this paper, three strategies are used to detect the risk area of a railway crossing: (1) we use a terrain drop compensation (TDC) technique to solve the problem of the concavity of railway crossings; (2) ...
