METHODS FOR DETERMINING THROUGHPUT CAPACITY OF RAILWAY LINES USING COEFFICIENTS OF ELIMINATION

The throughput capacity of a railroad line section means the maximum number of trains or train pairs that can pass through in a time unit (day, hour). The throughput capacity depends on the infrastructure (number of main tracks, signaling and safety devices, and telecommunications), type and power of the hauling means, mass and properties of the trains, as well as the organization of traffic. This article describes a procedure for determining the throughput capacity of railway lines using coefficients of elimination. The authors organized the traffic under non-parallel graphs, i.e., trains traveling at different speeds. In the non-parallel traffic graph, the throughput capacity of the railway line for freight trains is expressed by the number of freight trains of the set mass and speed, that can pass the section or railway line for the traffic of a given number of passenger trains, accelerated freight trains, and feeder trains. The authors conclude that the methods for calculating the railway line capacities are especially complicated under the conditions of mixed traffic and they are extremely sensitive to greater differences in train traveling speeds. The authors briefly discuss the use of these methods for calculating the railway line capacity at the Croatian Railways.
