Metro staff noticed flame under the out-of-service inbound railcar at the station about 8:30 p.m. and alerted fire officials.
During Fairfax County Fire Rescue’s fire response, a fire stand pipe burst and water flooded the station platform.
Authorities shut down power at the station. Firefighters found residual smoke coming from an electrical compartment under the car, officials said.
The station was closed for about an hour.
Metro spokesman Dan Stessel said Metro is investigating the cause of the fire.
“I would like take this opportunity to express our thanks to Fairfax Fire and Rescue for their response, ” said Stessel. “And also Fairfax Connector, which was prepared to send buses should they have been necessary.”
