Crews worked quickly to make the repairs to the support pole that was struck by the driver. Service was restored to the rail line just after 8am.
METRO Police Chief Tom Lambert says the wrecker driver who caused the accident has since been charged with DWI.
The driver was heading south on Fannin when he lost control of his wrecker truck near Ewing and smashed into a pole that holds up the wires for METRO rail, knocking that pole down.
While repairs were being made, METRO rail moved patrons between Wheeler and Hermann Park/Rice U stations using one track. The agency also had a bus bridge in place. METRO police officers were on the scene to help direct traffic.
The driver reportedly suffered minor injuries.
