Railway suicide is a significant public health problem. In addition to the loss of lives, these suicides occur in public space, causing traumatization among train drivers and passengers, and significant public transport delays. Prevention efforts depend upon accurate knowledge of clustering phenomena across the railway network, and spatial risk factors. Factors such as proximity to psychiatric ...

Railway is an Eco-Friendly and Popular mode of Transport in most major cities of the World. One of the most widely used and comfortable nodes of transportation system is train. As the railway network is considered to be the safest and easiest network. More than 10 billions of people and 1050 millions of freight travel by train annually. Railway Transport is indispensable in modern day life, bot...

The safety analysis of interlocking railway systems involves verifying collision and derailment freedom. In this paper we propose a structured way of refining track plans, in order to expand track segments so that they form collections of track segments. We show how the abstract model can be model checked to ensure the safety properties, which must also hold in the corresponding concrete track ...

The iron ore railway in northern Scandinavia is a single track line that stretches from the Gulf of Bothnia to the Norwegian Sea. Mixed traffic on a single-track railway makes the traffic sensitive and prone to disturbances. To improve punctuality and efficiency in the traffic flow, the link between disturbances and their impacts on train delays needs to be analysed and understood more precisel...

Travelling safely and comfortably on high speed railway lines requires excellent conditions of the whole railway infrastructure in general and of the railway track geometry in particular. The maintenance process required to achieve such excellent conditions is largely complex and expensive, demanding an increased amount of both human and technical resources. In this framework, an optimal schedu...

With the large-scale construction of city subways, the down traversing formed by subway running tunnels through the existing railways or railway yards are increasing day by day. Down traversing in shield method becomes common; however, the engineering cases which can be referable in the down traversing formed by the shallow-buried excavation of double-arch tunnels through the existing railways ...
