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...

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 ...

For real world railroad networks, we consider minimizing operational cost of train schedules which depend on choosing different train types of diverse speed and cost. We develop a mixed integer linear programming model for this train scheduling problem. For practical problem sizes, it seems to be impossible to directly solve the model within a reasonable amount of time. However, suitable decomp...

Market demands for different classes of rail transportation service are not served because of the inability to assess the cost to the network of disparate services, as well as the inability to determine optimal scheduling. A new scheduling model is presented, based on a multicommodity flow and discrete time, that both selects an optimal set of trains and schedules these trains over a time horiz...

In this paper, the train scheduling problem is modelled as a Blocking Parallel-Machine JobShop-Scheduling (BPMJSS) problem. In the model, trains, single-track sections and multiple-track sections respectively are synonymous with jobs, single machines and parallel machines; and an operation is regarded as the movement/traversal of a train across a section. Due to the lack of buffer space, the re...

In this paper we present an optimization model for train scheduling. This model constitutes one of the three major components of a solution approach for solving the transit network design problem. The problem of scheduling can be defined in the following general terms. Given the origin destination matrix for the train trips for design period, the underlying train network characterized by the ov...

The wagon flow scheduling plays a very important role in transportation activities in railway bureau. However, it is difficult to implement in the actual decision-making process of wagon flow scheduling that compiled under certain environment, because of the interferences of uncertain information, such as train arrival time, train classify time, train assemble time, and flexible trainsize limit...
