Ayase Station
Lines
Ayase Station is served by the following two lines.
The official boundary between the Joban Line and Chiyoda Line is located east of Ayase Station, past the turnoff for the Kita-Ayase branch of the Chiyoda Line. However, the segment of the Chiyoda Line between Ayase and Kita-Senju Station is treated as part of the Joban Line for fare calculation purposes when passengers do not travel on Tokyo Metro beyond Kita-Senju.
Ayase Station also serves as a turnaround point for the Odakyu 60000 series MSE Romancecar service through the Chiyoda Line, and is sometimes used as a delivery point for Tokyo Metro trainsets by rail; JR Freight transports the trainsets to Ayase during midnight hours, where Tokyo Metro takes delivery and hauls them to the nearby Ayase depot.
