Tsurumi rail accident
The Tsurumi rail accident (鶴見事故, Tsurumi jiko?, or "Tsurumi accident") occurred on November 9, 1963 between Tsurumi Station and Shin-Koyasu Station on the Tōkaidō Main Line in Yokohama, Japan, about 30 kilometres (20 mi) south of Tokyo, when two passenger trains collided with a derailed freight train, killing 162 people.
Accident
The 43rd wagon of a long freight train on the down-freight railway derailed and the two following wagons overturned, blocking the adjacent "up" passenger railway. Within seconds, a 12-carriage EMU train traveling to Tokyo collided with the freight wagons and the front three carriages derailed, falling into the side of the fourth and fifth carriages of another 12 carriage train passing on the down-line to Kurihama. The multiple collision left 162 dead and 120 injured.
Investigation
The initial JNR investigation found that the speed of the freight train (60 km/h) was not excessive, nor were any problems found with the line or rolling stock. For five years, the RTRI carried out tests on a test track using the same rails and rolling stock and found that the combination of wheelset design, rail cross section and wear, and track geometry all had a role in the derailment. As a result of the investigation, the old method of static track inspection was replaced with new track inspection cars employing dynamic inspection methods and data collection.[1]
