Modern train interval control systems contain communication channels between traffic organizers and the locomotive, using rail inductive as lines. The threads that make up these lines are an integral part of traction network and, therefore, current is channeled through them. Bearing this in mind, signals operate under conditions strong interference from current. At present, continuous automatic...

The development of High Speed Rail (HSR) in Europe has been encouraged and financially supported by the European Commission. Several lines are in operation, and many others under construction or waiting for approval. HSR technology is presented as a solution to congested roads and airports. Besides, rail transport is generally regarded as more environmentally friendly than other modes. However,...

A pricing methodology adapted to specific railroad infrastructures and the trains that use them is one way to ensure that railroad networks used by several different operators are used optimally. The diversity of railway networks (new lines and old lines) and services (long-distance and suburban passenger trains, freight trains, etc.) make it difficult to develop such a pricing methodology. Thi...

Rail wheel squeal on curves in rail track is a source of potential noise annoyance to residents adjacent to rail lines. For one private rail freight operator, wheel squeal was causing repeated complaints from neighbours. Wheel squeal can be caused by the wheel-tyre to rail-top interaction and the wheel flange interaction with the gauge face of the rail (more like a screech). This paper describe...

Departing from the present situation, this paper attempts to highlight future prospects of high-speed railways. A panorama of high-speed lines worldwide is first given and the limits of a further increase of rail speeds are surveyed. It is explained that rail high speeds are feasible only for large population concentrations. The impact of high speeds on the reduction of travel times is studied....

Today, Belgium, France, Germany, Italy, the Netherlands, Spain, the United Kingdom, China, Japan, Korea and Taiwan all have high-speed lines in operation. Many other countries, including Brazil, India, Morocco, Russia, Saudi Arabia and the United States, either have high-speed rail systems under construction or under development. Within the next few years, the world’s high-speed rail network co...

Cost-effective NDE of the vast length of ageing railway track around the world remains challenge for the community. Since continuously welded railway lines may be thought of as one-dimensional elastic waveguides, they are natural candidates for guided wave ultrasound, which offers the potential to interrogate a large length of rail from a single position. Continuously welded rail is installed i...
