National Police Corps Spokesman Ed Kraszewski
told Amsterdam television news AT5 that approximately 70 people had minor injuries and over 50 sustained serious to very serious injuries, including broken bones and spinal wounds.
Scores of ambulances were shuttling the injured from the site of the train wreck.
Television network AT5 posted photos on its website showing two trains that appeared to have collided head-on. The trains were both on the railroad tracks and severe damage near the point of impact close to exit doors was visible on a double-decker intercity train.
It is not yet clear how two trains could speed down the same track toward each other without setting off alarms. Kraszewski said the cause of the crash would be investigated.
The crash caused disruptions in train schedules throughout much of western Amsterdam and halted all trains running between the city's Central Station and Schiphol Airport.
