The National Transportation Safety Board has released a preliminary report on the Chicago train crash that injured 30 people last month. ABC News reports the NTSB says the train was traveling at 26 miles an hour when it crossed a fixed trip stop that activated the train's emergency braking system. But because of the train's speed the agency says the distance from the trip stop to the bumper post was too short to stop the train. The NTSB also says the crash caused nine-point-one-million dollars in damage to the station located at O'Hare Airport. The operator of the train has been fired after admitting she dozed off prior to the crash.
