JR East Shifts Track Maintenance to Daytime on Keihin-Tohoku Line

East Japan Railway Company is conducting daytime track maintenance on the Keihin-Tohoku Line from May 19 to May 21 ^[1].

The shift from traditional night-time work to daylight hours is part of a broader effort to promote "work-style reform" and improve operational efficiency ^[5]. By moving maintenance to the day, the company aims to reduce the physical and mental burden on workers who typically perform high-risk repairs during overnight shifts.

Between May 19 and May 21, the maintenance window is scheduled daily from approximately 10:30 a.m. to 3:30 p.m. ^[2]. The work is concentrated on the segment of the line between Tabata and Tamachi stations in central Tokyo ^[3].

During these specific hours, rapid services are suspended ^[4]. Only all-stop local trains will operate within the affected area to ensure continuous transit for passengers while crews work on the tracks. This arrangement avoids a total line shutdown, though it increases travel times for those relying on express services.

Passengers interviewed about the change expressed support for the initiative. One passenger said, "I think it's totally fine because I think night shifts are tough."

Another commuter noted the positive nature of the change, and said, "I think it's a very good thing. I think we will see what kind of effects it has from here on."

The initiative reflects a growing trend in Japanese infrastructure management to prioritize employee well-being over the traditional model of invisible, overnight maintenance. By utilizing the mid-day lull in traffic, JR East is testing whether daytime restrictions are a viable trade-off for a more sustainable labor model.
