HARPERS FERRY, W. Va. (WTHR) - A freight train crossing the Potomac River near Harpers Ferry derailed early Saturday morning.
The locomotive stayed on the tracks on the bridge but five cars behind it derailed.
Two of the cars fell into the water.
No one was injured.
The train was headed east over the Potomac from West Virginia into Maryland when an unknown mechanical issue caused the cars to derail.
A CSX spokesman told Eyewitness News the derailed train cars were empty and the company expects to resume traffic on the rails on Sunday.
CORRECTION: An earlier version of this story reported a partial bridge failure as the reason for the derailment. That has been corrected to indicate no damage to the bridge.
