Amtrack Train Crash - Philadelphia - 8 died, 200+ wounded: May 12, 2015

Level 3 mass casualty incident in Philadelphia (Frankford Junction, Port Richmond neighborhood on the 2000 block of Wheatsheaf Lane) Tuesday night at about 9:28pm, enroute to New York from Washington D.C., Amtrak Northeast Regional 188 carrying 238 commuters and five crew members derailed: 7-car train: the engine completely separated from the rest of the train, 2 cars upright, 3 cars on their side, 1 car upside down and decimated.
Amtrak's Northeast Corridor is 363 miles of track that connects Washington to Boston and is the busiest railroad in North America. Each day it carries more than three times as many riders between Washington and New York City as planes do.
"All the power cables that run parallel to the track caved in," Daniel Wetrin said. "There were cut cables hanging around."
Many passengers, including former Congressman Patrick Murphy, praised the scores of firefighters and police who arrived within minutes.
"Thank you so much to all the first responders-there w/in minutes," Murphy tweeted. "Thank you, thank you, thank you."
