Assessment of transportation capacity balance of railway network polygons
Introduction. Traffic and transportation capacities of railway polygons and traffic flows are not constant throughout the year. Permissible capacity levels are determined by the condition of unhindered reception of trains by stations. It is necessary to calculate the balance of transportation capaci...
