If a Shinkansen section includes no Shinkansen station connected with the regular railway line operated in parallel with the Shinkansen line, the section is dealt with a separate route (for example, the section from Shinagawa to Shin-Yokohama to Odawara).
並行在来線と接しない新幹線駅を含む区間（例：品川-新横浜-小田原）については別の路線として扱う。
