On the 20th, the Ministry of Land, Infrastructure, Transport and Tourism told JR East that some passengers had to stay in the car for more than an hour and a half due to a trouble that the train stopped on multiple lines in the Greater Tokyo area such as the Yamanote Line. I instructed them to verify that the evacuation time could be shortened.
From the evening of the 20th to the night, six trains in the metropolitan area, such as the Yamanote Line and Saikyo Line, could not be operated for up to four hours, and six trains stopped between stations, causing passengers to arrive. I got off the railroad track and walked to a nearby station to evacuate.
According to JR East, in order to get passengers off the railroad tracks, it is necessary to install temporary stairs on the doors of the leading cars and be accompanied by crew members, so the evacuation was started 50 after the trouble occurred. Minutes have passed.
Until the evacuation, the passengers stayed in the car where the air conditioner stopped due to a power outage, and some passengers had to stay for more than an hour and a half.
On the 21st, the Ministry of Land, Infrastructure, Transport and Tourism instructed JR East to verify whether it would be possible to shorten the time to evacuation, assuming that similar troubles would occur in the heat of the heat.
