Nearly a week after a train derailment killed eight passengers and injured over 50 more, Amtrak trains are once again running between NYC and Philadelphia. The 5:30 a.m. southbound train from NYC to Philadelphia was the first to go, and then a 5:53 a.m. northbound train from Philadelphia to NYC left with "about three dozen passengers" at 6:07 a.m.

On Tuesday, May 12th, Train 188, headed from Washington D.C. to New York City, derailed in Philadelphia at the Frankford Junction curve. The National Transportation Safety Board says that the train was going 106 mph, well over the 50 mph authorized speed. Apparently, in the last minute before the crash, the train accelerated from 70 mph to over 100 mph: "[NTSB] Board member Robert Sumwalt said it's unclear whether the speed was increased manually by engineer Brandon Bostian."

Yesterday, Amtrak CEO Joseph Boardman sent out this letter:

At Amtrak, the safety of our passengers and crew remains our number one priority. Since the tragic derailment, Amtrak staff and crew have been working around the clock to repair the infrastructure necessary to restore service for all the passengers who travel along the Northeast Corridor. Our repairs have been made with the utmost care and emphasis on safety, including complete compliance with Federal Railroad Administration directives.

Effective with departures from Philadelphia at 5:53 a.m. (Train 110) and New York City at 5:30 a.m. (Train 111) on Monday, May 18, Amtrak will restore normal service on the Northeast Corridor.

Although service along the Northeast Corridor will begin again tomorrow, the derailment of Northeast Regional Train 188 is a tragedy that we at Amtrak will continue to mourn and are dedicated to learning from.

Thank you for your support of America’s Railroad.

Amtrak President and CEO

On Saturday, the Federal Rail Administration ordered Amtrak to improve safety along its routes—like implement automatic train control—and to inspect the curves along the route to NYC.
