The process of accumulation wagons at marshalling yards with a firm timetable trains

The aim is to study sostavoobrazovaniya in marshalling yards and characterizing its parameters, as well as dependencies that determine these parameters and costs of car-hours of accumulation of wagons with solid graphics. Results: A detailed process of accumulation of cars on the train composition, as well as provides features wagons accumulation process with solid graphics. Practical significance: is a detailed examination of the process of accumulation of cars in view of admission of certain groups of cars that define the cost of wagon-hours to build cars. Their practical application will allow for more accurate and reasonably easy to normalize cars for accumulation, as well as to clarify the method of calculating the train formation plan.
