This is video from DC Fire & EMS Department videographer Vito Maggiolo of an incident Thursday afternoon where a locomotive caught fire at Union Station. According to the Washington Post's Clarence Williams, the fire may have been caused by an electrical or hydraulic problem. Suppression efforts were slowed as the train was towed to a track that was easier and safer for firefighters to reach.
Still pictures of the fire from Elliot Goodman can be found at DCFD.com. Here's some of what Elliot wrote about the fire:
Upon arrival units confirmed an Amtrak AEM 7 Engine with heavy smoke conditions. The fire consisted mainly of hydraulic fluids and oil and due to the construction of the locomotive it was a very nasty and stubborn fire to fight with companies taking lines inside the engine in an attempt to contain the fire.
Firefighters on the scene took a beating, especially with the temperature in the 90's. Units were on the scene approximately 5 hours.
