The proposed methodology for improving freight delivery enables the calculation of all types of shipments and reduces delivery time. It defines the decision-making process during the execution of various operations at stations. A model based on mathematical modeling of the technological process dependency is proposed for making effective decisions. To verify the methodology for standardizing transportation duration, it is necessary to organize the process considering the delay of each technological operation. The main reason for applying standards is to accelerate cargo delivery and ensure the proper distribution of penalties among railways for late delivery. In turn, this will help develop contractual relationships with clients and improve the overall system.
