Study on the operation mode of suburban railway at home and abroad and the inspiration to Beijing

As China's urbanization gradually enters the era of 'urban circle' and 'urban agglomeration', the suburban railway which is regarded as the way of connecting urban centers and suburban areas, such as Satellite city, as well as reshaping the layout of urban space, has been highly praised by the central government. In May 2017, the five ministries and commissions jointly issued the guidance on 'promoting the development of the urban suburban railway'. In the guidance, it is clear that the effective supply of the transit service of the suburban railway should be expanded. But in China, the city railway system and city traffic system belong to different traffic management department, and another problem which leads to such situation is that the division of labour and the function of railway system and urban traffic system are different for a long time. So how to operate the suburban railway in Beijing is an significant problem that needed to be solved.
