We have some exclusive video of the train derailment, four days after the incident. On Friday, February 10 a train traveling north on the Union Pacific railroad derailed sending numerous box cars into the water created by the Cosumnes River. Four days later we can see the aftermath now that the waters have receded. Union Pacific officials have said that they believe the flood waters may have been the cause of the derailment. The video appears to show that may have been the case.
