Abstract Capacity calculation and utilization is the core of railway transportation research. Heavy haul railways have attracted more attention due to their large-capacity, long-distance, multi-standard and other characteristics. The traditional method of calculating the capacity such as the subtraction coefficient method shows great incompatibility in the actual operation process. Such as the deduction standard is difficult to determine, and the parallelism of performance map is not obvious, affectting the accuracy of the calculation result. Based on the average minimum train interval method and the application of big data, this paper proposes a set of calculation methods suitable for the calculation of the capacity of heavy haul railway. Taking the typical heavy haul railway Baoshen South line as an example, applying this set of calculation methods to measure the capacity of each interval, the calculation results are more reliable and received on-site recognition.
