Graph methods for estimation of railway capacity

Railway capacity is the important characteristic that shows traffic potentialities of railways. Analytical methods of the calculation of the capacity of a single track are well known. Methods to estimate the capacity of a railway network and the railway direction are proposed in this paper. The railway network is represented in the form of a graph. Mathematical methods of the graph theory are applied in order to find the maximum flow. Parameters of tracks and stations are used in order to calculate the network capacity.
