AN ANLYTICAL MODEL FOR THE SIMULTANEOUS CALCULATION OF CAPACITY OF LINES, JUNCTIONS AND STATION TRUCKS

The calculation of capacity of railway lines is performed today by the railway management by using empirical or analytical methods. The paper aims at demonstrating the validity of the above-mentioned methods for each railway scheme upon their integration with analytical constraints for junction and station trucks capacity, components of a given ailway scheme Capacity is calculated as solution of a problem of a constrained optimum * An application of the proposed method is carried out for a real case of a medium complexity railway scheme This allows us to verify immediately its validity and to evaluate planning alternatives of management.
