Welded rails represent a critical element in the maintenance of a railway track. In the context of high-speed railway construction, the demand for efficient resource supply management, particularly concerning delivery timelines, is becoming increasingly stringent. However, existing research has inadequately addressed the logistical challenges associated with rail delivery. This study aims to assess the time-related aspects of welded rail deliveries and to propose strategies for minimizing the delivery time to end users. Methods: Simulation modelling has been employed as the research tool. Results: The analysis of the logistics chain for welded rail delivery for track maintenance has revealed various factors affecting the rail delivery timelines. The simulation model of the logistics chain has highlighted that a primary issue within the current rail delivery system for track maintenance is the insufficient availability of storage facilities. To minimize delivery times and eradicate delays, the proposal involves the integration of an intermediate storage warehouse into the system. Practical significance: The use of an intermediate storage warehouse will reduce the rail delivery time, decrease the downtime of the rail welding facility, and reduce the costs related to the supply of welded rails.
