The fire, which happened around 3:30 p.m. July 30, left 11 people injured, including multiple people who were hospitalized, and resulted in DART rail services being suspended in downtown for about a week, according to the NTSB report. At the time of the incident, the train was traveling from the Dallas Fort Worth Airport Station to the Parker Road Station when it stopped at a tunnel at Ross Avenue and U.S. Highway 75.
According to the report, the train contacted a catenary wire, which is a thin copper wire that hangs 20 feet above the train tracks and feeds power from the substations to the train. The contact caused arcing, otherwise known as electrical discharge, which caused the fire. The arcing lasted for 11 minutes, according to the report.
