Modeling and Costing of Passenger Train Delays

Delay is one of the most important problems of railway transportation systems, which has a lot of material and spiritual costs. Loss of passenger trust, waste of passengers' time, blockage in the one-lane system, depreciation of diesel, compensation to passengers, loss of fuel, etc. are just some of the costs incurred in the rail transportation system. No studies have been conducted in Iran on the cost of train delays. In the railway company of the Islamic Republic of Iran, billions of Tomans are imposed annually due to train delays, the amount of which are currently unknown and cannot be calculated. It is also possible to have a better sensitivity and understanding of delays when the amount of damage imposed on the system is clear and measurable. Therefore, in this research, first all the factors and sub-factors of delay are identified and then the separation and classification of all factors and sub-factors of delay along with their relationships are given in a schematic model and then using scientific and accurate costing, the amount of damage Each of the factors of delay in the passenger trains of the railways of the Islamic Republic of Iran, it should be specified that using this costing can be ranked different factors, the amount of damage to the railway company in different time periods and with Attention to the sensitivity that arises to the types of delays in order to improve, reduce and eliminate delays, as well as optimal investment management.
