Therefore, as a replacement, it is offered to fulfill the delivery deadlines. At the same time, in conditions of the privatized car fleet, a combination of criteria for meeting the deadline for the delivery of goods and minimizing the processing of car flows at technical stations was required. In the process of calculating the plan for the formation of one-group trains, all streams of car flows, from the furthest ones, are consistently considered. If the accepted conditions are not met, the procedure of combining distant ones with shorter streams with their processing at one, two, three, etc. stations is performed - until the proper level of organization is achieved. Keywords: railway, train formation plan, design norms, combinatorics, terms of cargo delivery, organization of car flows.
