The "bottlenecks" determination, limiting the througput of railway directions

The article describes methods of data receiving with using of an existing information systems about time parameters of freight trains movement on the explored rail directions; passing the testing freight trains to determine "bottlenecks" that limited the throughput with the modern traffic volumes and current technical equipment; simulation modelling of rail transportation processes for "bottlenecks" identification with the projected traffic and the development of technical equipment.
