Iogi

Departure data for this station is not available on this site.

Iogi Station opened on 16 April 1927 on the Seibu Shinjuku Line in Suginami, Tokyo. In a layout change on 21 October 1963 the original island platform was joined by a side platform, giving three tracks and so allowing trains to overtake. Until the road was grade-separated by the Iogi Tunnel, the point where the Loop Road 8 (Kanpachi) ring road crossed the line beside the station was one of that road's most notorious 'crossings that never open', and the jams it caused — kilometres long, and a sore point for more than twenty years — were compounded for passengers, who to reach the up platform from the north had to cross Kanpachi, enter by the south building and then use an at-grade crossing inside the station. Improvement work to prevent crossing accidents and to add a north entrance followed: demolition of the old south building began in 1996 and a new south building with automatic gates opened on 13 May 1997, with the up platform moved and a footbridge built between the platforms. After large-scale engineering carried out overnight, the layout was reconfigured on 14 March 1998 as two side platforms serving three tracks, the middle one a passing track, and the at-grade crossing inside the station was abolished. A new north building followed in 1999, and lifts on the north–south pedestrian subway were added in 2016.

When Iogi was rebuilt, a passing track was laid on the site of the old island platform, giving the station a track layout identical to that of Nakai Station; although the plan allows trains to be overtaken in either direction, in practice only up-direction services are overtaken here.
