Owned primarily by Amtrak, it runs from Boston in the north to Washington, D.C., in the south with major stops in Providence, New Haven, Stamford, New York City, Trenton, Philadelphia, Wilmington, and Baltimore. The NEC closely parallels Interstate 95 for most of its length, and, as of 2013, is the busiest passenger rail line in the United States both by ridership and by service frequency. The NEC carries more than 2,200 trains daily.

The next segment of the state highway is a C-shaped route through Havre de Grace on the west bank of the Susquehanna River. The third mainline section of MD 7 begins in Perryville on the east bank of the Susquehanna River and ends at US 40 a short distance west of the start of the fourth section, which passes through Charlestown and North East before ending at US 40, just west of Elkton. The fifth segment of the highway begins at South Street and passes through the eastern part of Elkton before reconnecting with US 40 east of Elkton and west of the Delaware state line.
The Philadelphia to Harrisburg Main Line is a rail line owned and operated by Amtrak in the U.S. state of Pennsylvania. This is the only electrified Amtrak line in the United States outside of the main line of the Northeast Corridor. The line runs from Philadelphia, where it meets the Northeast Corridor at Zoo Junction at milepost 1.9, west to Harrisburg, where electrification ends.

This section is sometimes referred to as "Keystone East" and is part of Amtrak's Keystone Service.
The Penn Line is a MARC passenger rail service operating between Union Station in Washington, D.C., and Perryville, Maryland, along the far southern leg of the Northeast Corridor; most trains terminate at Baltimore's Penn Station. It is MARC's only electrified line. With trains operating at speeds of up to 125 miles per hour (201 km/h), it is the fastest commuter rail line in the United States. The service is operated by Amtrak under contract to the Maryland Transit Administration. MARC sets the schedules, owns most of the stations, and controls fares, while Amtrak owns and maintains the right-of-way, supplies employees to operate trains, and maintains the rolling stock. It is the busiest of MARC's three lines, with twice as many trains and ridership as the Brunswick and Camden lines combined.
