Simulations are the core of every railway system. Changes in the timetable and the infrastructure, or even in the internal processes of a railway company should be, and usually are, first tested through simulations. Given their significance and potential impact, simulations should be primarily validated; validation ensures-at least to some extent-that the returned results are credible and can be used for the intended purpose. This study is a detailed report on two case studies from the railway sector. The aim of this paper is to identify critical factors that can advance or hinder the validity and the effective usage of simulation models.
