Four railway workers were killed in Japan after a Tokyo-bound express train struck them while they were carrying out weed-control work at Shin-Kanuma Station in Tochigi Prefecture on Thursday, August 20.
The accident happened at about 10:45 a.m. local time on the Tobu Nikko Line, as the Spacia X express train entered the station. The four workers were taken to hospital but were later pronounced dead, according to police and Tobu Railway, the operator of the line.
The victims included three workers and a supervisor, according to the Associated Press, citing police and the railway operator. Other reports from Japanese media identified the four men, but their names are not necessary to establish the circumstances of the accident and are omitted here.
Four workers were on the track
The workers were carrying out vegetation-control work on the railway line. Japanese reports said the wider work team included several people assigned to watch for approaching trains.
Tobu Railway said six other people at the site, including workers, lookouts and a supervisor, were unharmed. About 50 passengers were aboard the Spacia X train, and no passengers or crew members were reported injured.
The circumstances surrounding the collision are now the focus of an investigation.
Railway workers conducting maintenance near active tracks normally rely on designated lookout personnel to warn them when a train is approaching. According to Tobu, lookouts are expected to alert workers using signals such as flags, whistles or a microphone.
Japanese media reported that the train driver had received the prescribed signal indicating that workers had cleared the track. Tobu officials also said two lookout positions were involved and that the people responsible for those positions may not have been able to communicate with each other properly. The company said the details were still being investigated.
Possible communication failure under investigation
The early findings have raised the possibility that the warning system failed before the train reached the work area.
Kyodo News, cited by Japanese media, reported that a lookout positioned farther from the station was responsible for identifying an approaching train and signaling to another lookout closer to the work site. That second lookout was then expected to warn the workers and ensure they moved clear of the tracks.
Tobu said the two lookout personnel were not in a position to communicate with each other at the relevant time. It remains unclear exactly what happened between the moment the train approached and the collision.
The train driver’s account, as reported by Asahi Shimbun, was that the driver saw a signal indicating that it was permissible to enter the area and sounded the train’s horn as required. Investigators have not established why the workers remained on the track.
That distinction is important: a possible communication breakdown has been reported, but authorities have not publicly determined a final cause or assigned responsibility.
Train services were temporarily suspended
The collision caused a temporary suspension of services on part of the Tobu Nikko Line. Train operations resumed later on Thursday, according to the Associated Press.
The Spacia X is one of Tobu Railway’s limited-express services connecting Tokyo with destinations in Tochigi, including the Nikko area. Tobu’s published timetable shows Spacia X services operating through Shin-Kanuma on the route between the Tokyo area and northern Tochigi.
Tobu Railway apologizes
Takao Suzuki, head of Tobu’s railway business division, apologized following the accident and said the company would take preventive measures.
“We take this severe accident seriously, and we will ensure preventive measures and never let this happen,” Suzuki said, according to the Associated Press.
The company has said it is cooperating with authorities investigating the accident.
Japanese authorities have not yet announced a final explanation for why the workers were still on the track when the train entered the station. The investigation is expected to examine the communications between lookout personnel, the signals given to the train driver, and the procedures governing the maintenance work.
For now, the confirmed facts are that four railway workers died, the train’s passengers and crew escaped injury, and the precise sequence that led to the collision remains under investigation.
