AMSTERDAM (AP) -- Investigators are probing the cause of a head-on collision between two packed passenger trains near a park in Amsterdam that left scores of people injured, many of them seriously.
Amsterdam Mayor Eberhard van der Laan says 42 people were seriously injured in the crash Saturday evening between a double-decker intercity train and a commuter train.
Dozens more travelers escaped with minor injuries.
Dutch railway officials said Sunday that rail traffic around Amsterdam would be disrupted throughout the morning as the two damaged trains both remain on the tracks where they collided.
Two separate investigations will focus on whether human error or a mechanical fault led to the two trains winding up on collision course on the same stretch of track.
