Keiō Line
In July 1945, the terminal of the Keiō Line was relocated to the present location, though on the ground level, on the west side of Shinjuku Station. Keiō Shinjuku Station and Shōsen Shinjuku Ekimae Station were closed. This was because the trains faced difficulty in climbing up the slopes of the bridge over the governmental railway after one of the nearby transformer substations was destroyed by an air raid. The site of Keiō Shinjuku Station near Shinjuku-Sanchōme subway station is now occupied by two buildings owned by Keiō: Keiō Shinjuku Sanchōme Building and Keiō Shinjuku Oiwake Building.
