Two trains collided with each other at Kajigaya Station on Tokyu Railways’ Den-en-toshi Line in Kawasaki, southwest of central Tokyo, on October 5.

Company officials said a local train bound for Shibuya was entering Kajigaya Station at about 11 p.m. when it ran into a stationary out-of-service train.

The rearmost car of the out-of-service train derailed.

The officials said there were 149 passengers on the Shibuya-bound train, but none of them or any of the crew members were injured.

S/ Passenger / I waited inside the train for about an hour but it didn’t move, so I gave up and am walking home.

S/ University student / We were planning to go further by train. We have classes from the first period tomorrow, so we wanted to get home earlier. We can’t go to school (if the trains aren’t running tomorrow). It’s a problem.

According to the officials, the out-of-service train operated by a trainee driver changed directions at Kajigaya Station and was heading toward a rail yard.

But triggered by a signal indicating excessive speed, it came to an automatic stop before reaching its designated stopping point.

That was when the Shibuya-bound train was approaching the station.

The officials said the train’s driver noticed that the rear of the out-of-service train was protruding on the track it was traveling on and sent an emergency radio signal.

The signal caused the out-of-service train to become immobilized.

The Shibuya-bound train’s driver applied the emergency brakes but could not stop in time and collided with the other train.

From the morning of October 6, Tokyu’s train services were suspended between Shibuya and Saginuma stations on the Den-en-toshi Line and between Futako-tamagawa and Mizonokuchi stations on the Oimachi Line.

Long lines formed at bus stops near affected stations, while many people were seen commuting on foot.

Investigators of the government’s Japan Transport Safety Board came to examine the trains.

According to Tokyu Railways officials, the board completed its investigations and gave them permission to begin restoration work.

All train services were resumed by the end of the day on October 6.

The partial suspension resulted in the cancellation of 1,107 trains, affecting a total of about 652,100 passengers.
