From Fox 5:
“The derailment of a non-passenger train outside the Smithsonian Metro station last Thursday was caused by a track defect that was discovered on July 9 but not fixed, Metro said.
Following the derailment, Requa ordered a system-wide inspection of every mile of track, which could take up to a month to complete. He said customers can expect delays in the coming days as possible additional track repairs are made.”
