Abstract
Until now, railway facilities have been severely damaged by heavy rains, etc., and it took a long time to recover, and some lines have been abolished. In recent years, abnormal weather has become almost routine, and it is thought that the damage will increase and become more serious in the future. In addition, the new coronavirus (COVID-19) (hereinafter referred to as corona), which spread this year, has greatly reduced the movement of people. And Corona has significantly deteriorated the management of railway operators nationwide, and the abolition of regional railways is becoming a reality.
In this paper, we examined the impact of such exogenous damage on the railway business from a medium- to long-term perspective, and showed that the impact will increase in the future. Next, we consider regional railways in terms of providing easy-to-use service levels, their sustainability, the rationality of the amount of publicly funded projects, resilience to natural disasters and corona, and early recovery., It was shown that there are problems with the existing vertical separation measures. And we have shown that the public-private shared vertical separation meets all of these requirements.
