• JR Musashino Line: Shin-Akitsu ⇄ Nishi-Kokubunji

Shin-Kodaira Station opened on 1 April 1973 in the city of Kodaira, Tokyo, as a stop on the Musashino Line, then operated by Japanese National Railways and inherited by JR East at privatisation in 1987. The station sits in a U-shaped reinforced-concrete cutting between the 4,381-metre Higashimurayama Tunnel and the 2,562-metre Kodaira Tunnel, with two side platforms 7.4 km from the line's western terminus at Fuchūhommachi. In October 1991, after weeks of record rainfall and Typhoon 21, groundwater pressure heaved a 120-metre length of the cutting upward by as much as 1.3 metres, pouring sediment-laden water into the station. Service was severed for two months until rebuilding finished on 11 December 1991.

During the 1991 closure, JR East considered building a temporary footpath between Shin-Akitsu and Akitsu stations so passengers could transfer to the Seibu Ikebukuro Line, but local shopkeepers blocked the plan over fears the path would become permanent.
