Amtrak has restored full service on its Northeast Corridor.
Commuter service between Philadelphia and New York City had been halted for a week, after a derailment killed eight people.
But on Monday morning, trains began rolling. The Associated Press reports:
"Amtrak resumed service along the corridor with a 5:30 a.m. southbound train leaving New York City. The first northbound train, scheduled to leave Philadelphia at 5:53 a.m., was delayed and pulled out of 30th Street Station at 6:07 a.m.
"About three dozen passengers boarded the New York City-bound train in Philadelphia, and Mayor Michael Nutter was on hard to see the passengers and train off.
"All Acela Express, Northeast Regional and other services were to also resume."
Amtrak President & CEO Joe Boardman said in a statement: "The safety of our passengers and crew remains our number one priority. Our infrastructure repairs have been made with the utmost care and emphasis on infrastructure integrity including complete compliance with Federal Railroad Administration directives."
