Simulation Services to Support the Control Design of Rail Infrastructures

The design of rail infrastructure is a difficult task. Many parties are involved, and the tasks range from stakeholder issues to very detailed technical questions, such as control design. Simulation studies are often applied during infrastructure control system design, but the application of simulation is quite hard. One of the problems is the lack of flexibility in linking to information systems and databases. Another problem is that there are many potential users of the models, while most simulation systems can only be used by one user at a time. In addition, the tightly coupled structure of models makes model reuse and model maintenance hard. To overcome these problems, a service oriented simulation architecture is proposed for rail infrastructure modeling. The object-oriented simulation libraries that have been created within this architecture have been tested in a real project to estimate rail infrastructure capacity, and proved to work well
