Train service on the JR Tokaido Line was suspended between Tokyo and Shinagawa stations for nearly three hours Sunday morning, inconveniencing some 22,000 passengers, railway officials said.

At around 6:30 a.m., a one-car cargo train came to a halt near Shinbashi Station on the line after failing to accelerate and was stranded there for about 1 hour and 40 minutes, the officials said.

The incident led to cancellations of 21 train runs on the line and delays of up to two hours and 50 minutes for 24 train runs.
