Abstract
In this paper we address a variant of the freight train routing problem to estimate the residual capacity in railway networks with regular passenger services. By ensemble averaging over a random temporal distribution of usable slots in the network, bounds on the number of additional freight trains on predefined relations are established. For the solution, a two-step capacitated routing approach based on a time-expanded network is used. The approach is applied in a case study to freight relations in the railway network of North Rhine Westphalia.
