Construction of computing methods of railway stations based on system approach

The article reveals the problem of correct constructing of computing methods of railway stations. The authors introduce a new principle of correctness - the coincidence of the functional role of the calculation element in reality and the model. For a station, the functional role is the structural support of the process operation. And the paper considers the existing computing methods of yards and yards necks. The ways of their improvement are proposed.
Keywords: computing method, functional role, yard, yard neck, process operation
