The problem of train planning or scheduling for large train stations is considered. We propose discrete event modeling of railway station and methods of supervisory control. The main purpose of DE-modeling of a complicated object is to study the dynamic of the process as a sequence of events (language model). This model is very productive for many problems of transport systems with complicated structure (Janczura, 1998; Decknatel and Schnieder, 1998; Diana et al, 2001; Fanti et al, 2006; Giua and Seatzu, 2008), such as routing problems, platforming, scheduling. DS-model describes the structure of the transport system and its behavior, it is determined by the language; the specification sets limits on its behavior, and the supervisor provides the implementation of this specification. Such separate modeling of the structure, conditions and control reduces the complexity of algorithm.
