Abstract
This paper describes a constraint-based model of the train circulation management problem. The basic concepts of the model are activities, resources, time and allocation constraints. The problem is formulated as a joint scheduling and allocation problem, i.e. there exist degrees of freedom for deciding both which activities to perform and when, and which resources to allocate to these activities. The real life application for the experiments is a railway -node near Paris-Nord train station, this node has been chosen because it is a complex junction and the traffic due to North TVG, Eurostar, Thalys and freight trains will notably increase in the years to come. 1. The train circulation m
