Japan Train Derails

Several people are still trapped in wreckage hours after a train crash killed at least 50 people in Japan, the deadliest rail accident in the country in four decades. The accident happened  in an urban area near Amagasaki.

Fire officials say rescuers have found four people alive in the wreckage. It remains unclear what the condition of those still trapped is.

A packed commuter train jumped the tracks and hurtled into an apartment complex in a city 250 miles west of Tokyo. Some 340 people have been hurt.

Speed and the driver's inexperience may have played a role in the crash. A Japanese news agency reports the automatic braking system at that stretch of track is among the oldest in Japan.

The older system is less effective in halting trains traveling at high speeds.
