The aim of this study was to identify bottlenecks in the container handling process at the port and simulate the proposed scenarios in a true port with a lean railroading approach. After 160 hours of visiting the selected port and holding a full 30-hour meeting with the authorities, all container-related processes have been identified. In this study, entry and exit times to each area were used for all containers transported by rail in the year 1396, including 19,000 records. These data were completed by timing the process of container transport between the rail yard area and the berth in the port. . Using the Lean Study Approach, a value stream map of these processes has been prepared and simulated the current port state using the AnyLogic simulation software. The proposed scenarios focused on time / cost / operations / equipment and infrastructure were developed and simulated. The results show that the proposed two solutions are effective in reducing time and cost by up to 20%. Also, the case study port, without having to pay for the purchase of equipment and infrastructure, has the ability to increase the share of rail to eight percent. On the other hand, with increasing container operations, one of the most important bottlenecks for the container port is the container terminal. Also, reducing the cycle time of wagons and accelerating their movement is one important tasks of the railway company in the context of increasing the share of rail. It is suggested that the Ports and Maritime Organization, providing infrastructure and operational requirements for the port, the railway company, set up scheduled freight trains and provide the required fleet and, customs with the facilitation of clearance clearance processes in order to propagate the burden to this approach
