(I think this happened a few months ago but I just read about this train that ran off the tracks!)
After investigating the derailment of a train in Liberty, South Carolina, Norfolk Southern discovered that a number of factors led to the derailment. Damages are estimated at over $1.5 million and possibly contaminated soil was still being moved a month after the accident (6,200 tons total).
According to one of the investigators the reason the train derailed was that the wheels of the train moved from side to side and when the train began to decelerate a wheel climbed up off the tracks. What is frightening is that apparently this motion is extremely difficult to detect. Fortunately Norfolk Southern is looking into deploying a new “truck hunting” technology that detect car with this condition.
