This paper organizes the issues on what type of policy response should be taken concerning large scale renewal of high-speed railways, which is expected to occur frequently in the near future. The need for a new policy framework with a view to large scale renewal is claimed from the perspective of whether the current project assessment method assumes large scale renewal, whether, in particular, a parallel conventional train line among alternate transportation and alternate railway lines can function as a receptacle to take on the demand during the renewal, and what the cost burden and administrative support should be during the renewal.
