Many questions remain about the deadly Amtrak crash that occurred Tuesday night on a busy stretch of railway just north of Philadelphia. But here’s what we know so far:
How did it happen?
According to law enforcement sources who spoke with NBC News early Wednesday, officials were eyeing speed as a possible cause. The crash occurred near a section of track that curves, forcing passing trains to slow down from 70 mph to 50 mph. One of America’s worst train disasters actually occurred in almost that exact location 71 years ago, though that accident was blamed on mechanical failure, not speed.

Two sources close to the investigation confirmed to NBC News Wednesday afternoon that the train was in fact traveling at a speed faster than 100 mph, according to information recovered from the train’s event recorder.
More time is needed to determine whether human error or equipment failure played a role.
Where and when did it happen?
The crash occurred near Frankford Junction on the 2000 block of Wheatsheaf Lane, shortly after 9 p.m. Tuesday. The train was heading to New York from Washington, D.C. when all seven train cars came off the track.
The location of the crash is very close to the site of the 1943 Frankford Junction train wreck — one of the worst in history — which killed 79 people and injured 117 others. Investigators determined that wreck resulted from an overheated journal box that caused an axle to snap.

Who are the victims?
Of the 238 passengers and five crew members aboard the Amtrak Regional 188, at least seven people were killed and more than 200 people injured after the train derailed and rolled onto its side Tuesday night. Officials have not yet released the identities of the deceased victims, although the Naval Academy issued a statement Wednesday naming a midshipman as one of the passengers who lost their life.
“The midshipman was on leave and enroute to their home of record when the accident occurred,” read the statement. “The Brigade of Midshipman, staff and faculty were notified of the midshipman’s death this morning. Out of respect for the family’s privacy, the identity is being withheld for 24 hours after next of kin notification. The Naval Academy is supporting the midshipman’s family, friends, and loved ones during this time of grief.”
