This annotated bibliography aims to collect and classify the available literature on analytical models for rail systems. Various network, yard, and scheduling models are cited, together with some references providing the institutional background. The bibliography focuses on models of interest to the operations research community. Both simulation and optimization models are discussed with special emphasis on the latter. It is hoped that this compilation of previous work will facilitate the growing efforts in developing rational planning systems for rail transport and furthermore motivate operations researchers to look into this rich modelling area.
