This paper presents the problem of scheduling security teams to patrol a mass rapid transit rail network of a large urban city. The main objective of patrol scheduling is to deploy security teams to stations of the network at varying time periods subject to rostering as well as security-related constraints. We present several mathematical programming models for different Variants of this proble...

In the United States, the freight railway industry is already running without much excess capacity. Hence, better planning and scheduling tools are needed to effectively manage the scarce resources, to cope with the rapidly increasing demand for railway transportation. The integration of freight train and passenger train scheduling and dispatching is an important railroad management task since ...

Abstract Rail freight transportation is involved with highly complex logistical processes and requires a lot of resources such as locomotives or wagons. Thus, cost-efficient strategies for routing cars in cargo network are great interest railway companies. When it comes to single wagon load traffic, trains usually formed by collecting individual into batches at shunting yards, order transport t...

Accession of the Republic of Poland to the European Union (EU) has committed Poland to adopt, among others, policy of opening up the market of products and services in the area of rail transport. Follow decision about the opening of the EU market and transport services for rail transport, the European Parliament and of the Council have introduced a number of safety and interoperability directiv...

ABSTRACT The quality of ride is predominantly controlled by the design of the secondary suspension in rail vehicles. That is why air springs are increasingly important suspension component in rail vehicles. This is necessary for higher preload, higher speed as well as improved ride dynamics and noise levels. These necessities have created an interest for modeling the air springs for the simulat...

The scheduling of train services is subject to a number of constraints describing railway infrastructure, required train services and reasonable time-intervals for waiting and transits. Timetable planners at Dutch Railways are nowadays supported by a software tool, called CADANS, which produces a feasible timetable on an hourly basis. In this paper, connection requirements between train series ...
