JR East began performing rail maintenance during daylight hours on the Keihin-Tohoku Line starting Tuesday [1].
This shift in scheduling represents a move toward labor reform for railway employees who traditionally work overnight. By moving maintenance to the day, the company aims to ensure a better work-life balance for staff and improve overall operational safety [2].
The work is taking place between Tabata and Tamachi stations [1], [3]. The project is scheduled to run from May 19 through May 21 [1]. On Tuesday, work began at 11 a.m. and concluded at 3:30 p.m. [1].
To facilitate the maintenance, rapid train service was temporarily suspended during the work windows [1]. The change in timing also allowed for an increase in the total work duration. The daily operational window grew to approximately six hours, an increase from the previous average of four hours [1].
Tatsuya Shino, a facility unit leader for the JR East Metropolitan Area Headquarters, said the company has received many requests from employees wanting to secure a better work-life balance through daytime work [1].
While the company focuses on labor health, some commuters expressed mixed feelings about the disruption. One passenger said that while they believe night shifts are difficult and support the change, they feel the impact on those who use the trains [1].
This initiative is part of a broader effort to increase efficiency and reduce the physical toll of nocturnal labor on the workforce [2].
“The company has received many requests from employees wanting to secure a better work-life balance through daytime work.”
This transition highlights a growing tension in Japanese infrastructure management between the 'work-style reform' movement and the demands of high-frequency urban transit. By prioritizing the circadian health and safety of workers over uninterrupted service, JR East is testing whether the public will accept daytime disruptions in exchange for more sustainable labor practices.
