Amtrak operates the following lines:

• Northeast Corridor: Connecting Washington, D.C., to Boston, Amtrak owns 367 of the 457 miles of track, collaborating with several commuter agencies on the remainder.
• Keystone Corridor: This 104.2-mile stretch from Philadelphia to Harrisburg, Pennsylvania, underwent significant upgrades for electric service, achieving speeds of up to 110 miles per hour due to a partnership with Pennsylvania.
• Empire Corridor: Amtrak maintains the 11 miles from New York Penn Station to Spuyten Duyvil and leases an additional 94 miles from CSX between Poughkeepsie and Schenectady.
• Michigan Line: Acquired from Conrail in 1976, Amtrak took over the west end of the former Michigan Central main line, covering 98 miles.
• New Haven–Springfield Line: The 62-mile stretch between New Haven and Springfield was purchased from Penn Central in 1976.
• Post Road Branch: A 12.42-mile line extending from Castleton-on-Hudson to Rensselaer, New York.

Amtrak owns station and yard tracks in major cities like Chicago, Los Angeles, New Orleans, New York City, and Washington, D.C., while leasing additional tracks in Florida.

Amtrak is the proprietor of New York Penn Station, Philadelphia 30th Street Station, Baltimore Penn Station, and Providence Station, as well as Chicago Union Station. The Washington Terminal Company, largely owned by Amtrak, manages rail infrastructure around Washington Union Station.

Three active service lines:

• Northeast Corridor: Handles the high-speed Acela and Northeast Regional trains.
• State Supported: Facilitates service on routes under 750 miles through state funding agreements.
• Long Distance: Covers routes exceeding 750 miles, benefiting from federal financial support.

Three service lines focusing on operations beyond Amtrak trains:

• Ancillary: Manages commuter train operations under contract, Amtrak Thruway services, charter trains, and transportation of private railcars.
• Real Estate & Commercial: Oversees Amtrak’s property, including leasing space within stations.
• Infrastructure Access/Reimbursable: Charges other railroads for track access and offers reimbursable services to them or state governments. Revenue from these lines supports Amtrak’s broader operations.

Classes of Service

Amtrak provides four levels of service: First Class, Sleeper Service, Business Class, and Coach Class.

• First Class: Available on the Acela, featuring more spacious seating in a separate car from Business Class, which is located at the rear of the train to minimize aisle traffic. First Class includes amenities like hot towel service, complimentary meals, and alcoholic beverages, along with access to lounges at major stations.
• Sleeper Service: Offers private accommodations on long-distance trains, including roomettes, bedrooms, and family suites. Attendants may provide full meal services, and rooms can be converted to sleeping areas at night.
• Business Class: Available on the Acela, Northeast Regional, and select other routes, featuring reclining seats with extra legroom, power outlets, and complimentary non-alcoholic beverages. Access to lounges may vary by location.
• Coach Class: The standard service on all trains except the Acela, with reclining seats equipped with power outlets. Long-distance coach cars often have fewer seats to provide additional legroom.
