Nowadays railway systems are designed and tested in a conventional way, i.e. the systems are simulated with a manually created test bench. This has the advantage that the designers have a considerable expertise with this kind of work, but there is still a lot of potential for human failure. Furthermore, testing is very cost-intensive and can never reach complete coverage. Hence, an integrated d...

1 Chinese railway system serves as an important role for the economy of China and the travel needs 2 of its citizens. As China is subject to frequent earthquake events, it is important to investigate 3 how to strengthen the railway system to retain its service after earthquakes. This paper proposes a 4 comprehensive methodology to suggest the optimal investment plan using historical earthquake ...

The provision of appropriate quality rail services has an important role in terms of railway infrastructure: quality of infrastructure maintenance, regulation of railway traffic, line capacity, speed, safety, train station organization, the allowable lines load and other infrastructure parameters. The analysis of experiences in transforming the railway systems points to the conclusion that ther...

We propose a new dynamic row/column management algorithm for freight train scheduling in a single track railway system. While many papers have already been devoted to train scheduling, previously published optimization models still suffer from scalability issues, even for single track railway systems. Moreover, very few of them take into account the capacity constraints, i.e., the number of alt...

Today the railway timetabling process and the track allocation is one of the most challenging problems to solve by a railway company. Especially due to the deregulation of the transport market in the recent years several suppliers of railway traffic have entered the market in Europe. This leads to more potential conflicts between trains caused by an increasing demand of train paths. Planning an...

This study investigated trespassing accidents, trespassing and related countermeasures to provide information for prevention of trespassing accidents on Finnish railways. The study includes five complementary substudies, of which two included accident analyses and three collected information on railway trespassing by means of surveys, interviews and field observations. The main results showed, ...

A formal theory of an application domain can serve a key role in formal specification and verification of systems operating in that domain. This is particularly relevant when working with families of similar systems intended to control some kind of industrial process or function where the control principles are general while the specifics of the system depend on the particular installation the ...

The European Railway Agency (ERA) has the challenging task of establishing Common Safety Targets and Common Safety Methods throughout Europe. In this context, the harmonization of risk assessment methods is also discussed. The purpose of this paper is to present a new approach to risk assessment of technical systems in railway automation, which allows a rapid risk assessment while at the same t...

Ever since the dawning of computers and its related technologies, railway has been one of the major application domains in which wide variety of information and communication technologies are successfully utilized. Substantial efforts have been made in such fields as transportation planning, passenger information services (including seat reservations), train control, and train traffic managemen...

With the large-scale construction of high-speed railway, the impact of its high speed on Orthogonal Frequency Division Multiplexing (OFDM) channel estimation has caused a wide range of concern. This paper studies the OFDM systems in high-speed railway environment and its channel estimation using least square (LS) method. In the simulations, we take into account Doppler frequency shift, antenna ...
