JR East to Suspend Yokosuka Line Services Between Tokyo and Shinagawa on September 5
JR Hokkaido has announced that it will resume services on the Muroran Main Line between Toyoura and Date-Mombetsu stations from the evening of September 2, following damage caused by heavy rain on August 27. Services between Oshamambe and Toyoura stations will remain suspended.
Between Usu and Nagawa stations, a non-revenue train collided with fallen trees that had flowed onto the tracks along with mud near the entrance to the Shin-Entomo Tunnel due to the heavy rain on August 27, causing it to derail. The derailment extended for approximately 170 meters, and restoration work is still underway.
Meanwhile, between Shizukari and Koboro stations, the trackbed was washed away, mud flowed onto the tracks at multiple locations, and the tracks were flooded. Although services were initially expected to be suspended until September 2, the full extent of the damage has since become clear, and restoration is now expected to require additional time. Resuming services will be difficult until at least September 6, with restoration targeted from September 7 onward.
Until September 1, services between Oshamambe and Date-Mombetsu stations will be suspended throughout the day, with 42 trains canceled per day. All Hokuto limited express services connecting Sapporo and Hakodate stations will be canceled. All local trains between Oshamambe and Date-Mombetsu stations, as well as some local trains between Date-Mombetsu and Tomakomai stations, will be canceled. On September 2, services between Oshamambe and Toyoura stations will be suspended throughout the day, with 39 trains canceled. All Hokuto limited express services will remain canceled, while some local trains between Oshamambe and Tomakomai stations will be canceled.
Replacement transportation has been in operation since August 30. JR Hokkaido said it will announce service conditions and replacement transportation arrangements for September 3 onward at a later date.
