In this work, the railway freight transportation network design problem is addressed taking into account a set of specific considerations. Products to be transported are classified into two groups: priority (e.g. perishable goods) and non-priority. The rail network is composed of yards and tracks. Trains are composed and decomposed at yards, and a subset of yards, the terminals, are origin or destination of goods. Each product can only be transported by a small subset of railcar types. Due to physical conditions, not all the railcar types can run on all the tracks (for instance, if we have different track gauges on the network). Also, priority trains can only run on certain tracks. The problem is formulated as an MILP problem and results for small to moderate networks are presented. The model is initially solved using CPLEX although several possible alternative algorithmic possibilities are discussed.
