This paper focuses on the changes in the accessibility of railway passenger transport network in the Beijing-Tianjin-Hebei region before and after the opening of the Beijing-Zhangjiakou high-speed railway. It mainly uses for models: a spatial model based on node location, cost model based on travel expenditure, model based on weighted average travel time, model based on economic potential index. These four models, combined with the required data, give the accessibility of the Beijing-Tianjin-Hebei railway passenger transport network before and after the opening of the Beijing-Zhangjiakou high-speed railway. The results of these calculations are visualized and analysed. The conclusions are as follows: (1) After the opening of the Beijing-Zhangjiakou high-speed railway, the accessibility of most cities in the Beijing-Tianjin-Hebei region is found to be enhanced. (2) Accessibility of some cities is found to be decreased in some models. (3) For different accessibility models, the degree of accessibility change of each city is different. (4) After the opening of the Beijing -Zhangjiakou high-speed railway, the accessibility distribution of Beijing-Tianjin-Hebei is still different.
