In this paper, we describe a new model for the Train Unit Shunting Problem. This model is capable of solving the matching and parking subproblems in an integrated manner, requiring a reasonable amount of computation time. Furthermore, the model incorporates complicating details from practice, such as trains composed of several train units and tracks that can be approached from two sides. Computational results are presented for real-life cases of NS Reizigers, the main Dutch passenger railway operator.
