A Chicago train crash during morning rush hour injured 33 people when two trains collided on Sept. 30. According to Reuters, the trains collided in Forest Park, a suburb just west of Chicago.
One of the trains was sitting at the station and the second crashed into it. Investigators are looking into the accident which caused 33 people to be transported to nine area hospitals after the Chicago train crash.
The service on the train line was halted for two hours and one of the train operators was hospitalized as well.
The second train that caused the accident was empty, which is raising eyebrows as investigators investigate to see if someone might have deliberately set the train in motion. At the moment, mechanical failure is the leading cause. The empty train was traveling at about 20 mph when it struck the other train.
A Chicago Transit Authority spokesman said that no criminal activity is indicated, but they will look into everything to make certain foul play was not at hand here. Surveillance cameras should shed light on the questionable empty train, as the entire trip should have been recorded.
The empty train that caused the Chicago train crash had been at a repair yard since Sept. 23.
