Editor's note: If you're just waking up or commuting in the New York City and New Jersey area today, here's the latest: Train service resumed on all Northeast Corridor and North Jersey Coast lines at 5:30 a.m. ET, but residual delays are expected as the investigation in Elizabeth, NJ, continues. Amtrak also says that Acela Express, Northeast Regional and other services will operate Monday with some schedule modifications, so passengers should expect cancellations and delays throughout the day. In Manhattan, West 23rd Street between Sixth and Seventh avenues remains closed as police continue their investigation into Saturday's explosion in Chelsea. PATH trains are skipping 23rd Street in Manhattan, and PATH will cross-honor New Jersey Transit passengers. MTA's 1, E and F trains have resumed normal stops at 23rd and 28th streets. - Rebecca
The National Railroad Passenger Corporation, doing business as Amtrak/ˈæmtræk/, is a passenger railroad service that provides medium- and long-distance intercity service in the contiguous United States. Founded in 1971 to take over most of the remaining U.S. passenger rail services, it is partially government-funded yet operated and managed as a for-profit corporation.
Amtrak serves more than 500 destinations in 46 states and three Canadian provinces, operating more than 300 trains each day over 21,300 miles (34,000 km) of track. Some track sections allow trains to run as fast as 150 mph (240 km/h). In fiscal year 2015, Amtrak served 30.8 million passengers and had $2.185 billion in revenue, while employing more than 20,000 people. Nearly two-thirds of passengers come from the 10 largest metropolitan areas; 83% of passengers travel on routes shorter than 400 miles (644 km). Its headquarters is at Union Station in Washington, D.C.
The name "Amtrak" is a portmanteau of the words "America" and "trak", the latter itself a sensational spelling of "track".
