This time yesterday morning, we woke up to a lot of confusion.  What caused an Amtrak train to not only detail, but also cause so much destruction?

Federal investigators say that the train was going over 100 mph prior to the crash.  The speed limit was 50 mph turning a curve, and 70 mph prior to that.  According to ABC News, the engineer's name was Brandon Bostian, 32, of Queens.  He was approaching a turn at roughly 106 mph, and was hitting the breaks to slow down.

Brandon is willing to submit a blood test and his cell phone, but has yet to answer to authorities as to why he was going so fast.  He suffered a concussion in the accident, as well as a head wound.  The train derailment killed seven passengers, and injured 200.

If you were planning on using Amtrak today, there are a few things to know. According to The Press of Atlantic City:

New Jersey Transit announced that the Atlantic City Rail Line is suspended between 30th Street in Philadelphia and Cherry Hill due to the derailment. Busing is being provided and N.J. Transit said is cross honoring Amtrak tickets for Rail, Southern Division buses and the River Line.
