The Daily Yomiuri reports on another Yamanote line goof:
Five hundred people found themselves trapped aboard a late-night train on Tokyo's JR Yamanote Line for 40 minutes Friday after a faulty door indicator caused the train to come to an unscheduled stop.Like I said the last time this happened less than two weeks ago I can't imagine being stuck on an immobile train for that long. At least this time it wasn't rush hour.
...About 500 passengers were trapped onboard the train for about 40 minutes as the conductor inspected the train. Nothing out of the ordinary was found, and service eventually resumed, the official said.
The indicator malfunction caused 18 trains traveling in both directions around the loop line to be delayed up to 39 minutes, affecting 21,000 passengers.
