Topic: Mystery Smoke in DC's L'Enfant Metro Station

[Libertas]

Though an exact cause of the smoke and fire is unknown, NTSB investigators said there was an electrical arcing involving the third rail and the power supply cables to that rail prior to the fire. There was water along the tracks near the accident scene, which would have helped facilitate smoke along the third rail, investigators said.
