Amtrak, the UsefulNotes/{{trademark}} name of The National Passenger Railway Corporation, is the national railway of the United States. Privately-owned passenger trains in the US had always operated at a loss. As car ownership and passenger flights exploded following UsefulNotes/WorldWarTwo, many railroad companies were going out of business, in part because the government required them to provide service.

So Congress passed a law ending this requirement and replacing it with a skeletal network that became Amtrak. It began service in May of 1971. Though ridership has rebounded enormously since then, the network is run on a very small budget, so certain priorities have to be set. In the most heavily populated region, the Northeast, the rail system is extensive enough to rival those of Europe and includes a high-speed line. Everywhere else, it's famous for massive delays and unreliability, although high-speed rail is set to be extended to other regions in the next decade (the "[[UsefulNotes/{{Chicago}} Chicago Hub]]" region--which extends from Cleveland and Detroit to Kansas City east-west and Minneapolis to Louisville north-south--has seen particularly extensive improvements to Amtrak in preparation for it). But if media depict a passenger train in the contemporary US, it will most likely be an Amtrak train.

'''Important Stations'''

* Penn Station, UsefulNotes/NewYorkCity is the busiest station in the United States. The original station was a beaux-arts masterpiece that was controversially demolished in 1964 to build the new Madison Square Garden, and the entire station complex is now underground. Amtrak is currently planning to move the station to the James Farley Post Office and will rename it Moynihan Station in honor of the late U.S. Senator Daniel Patrick Moynihan, who created the idea of rebuilding the historic Penn Station.

* Union Station, UsefulNotes/WashingtonDC is Amtrak's headquarters, the second busiest station, and just a few blocks from the capitol building.

* 30th Street Station, UsefulNotes/{{Philadelphia}} is the third busiest station, as it is on the Northeast Corridor and the terminus for every train into the interior of Pennsylvania.

* Union Station, UsefulNotes/{{Chicago}} is the fourth busiest station, hub of the entire Midwestern rail system and the starting point of all but one route to the west coast.

* Union Station, UsefulNotes/LosAngeles is the fifth busiest station and something of an oddball. It's designed to look like a [[UsefulNotes/{{Spain}} giant mission-style church]] complete with gardens, the tracks and platforms are elevated, and it's been in a state of constant expansion since 1989. It was a major hub for [[GoldenAgeOfHollywood Golden Age movie stars]] and [[UsefulNotes/WorldWarTwo troops bound for the Pacific]], and you've seen it many times if you watched ''[[Series/TwentyFour 24]].''

'''Major Routes'''

* ''Northeast Corridor'' runs from [[ExactlyWhatItSaysOnTheTin Boston to Newport News]] and stops in every major city in the northeast. Due to the area's high population density, it is one of the few Amtrak lines that turns a profit; it and the Acela Express together generate more than half of the entire system's revenue.

* The ''Acela Express'' is currently America's only high-speed line, running from UsefulNotes/{{Boston}} to UsefulNotes/WashingtonDC. It manages to run on normal tracks by tilting the cars with hydraulics. The ride itself is very smooth and eerily quiet, though a lot slower than comparable systems in other countries -- the average speed (including stops) is only 80 miles per hour (130 km/h), only reaching its top speed of 150 miles per hour on a few stretches (240 km/h). Expect to see members of Congress from the northeast riding it to/from DC at the beginning and end of each week, or people traveling between UsefulNotes/NewYorkCity and Boston (more than half of all train and air traffic between the two cities is on Acela). On that note, its success has essentially killed commuter air shuttles on the East Coast, thanks to its speed, convenience, and lack of OverreactingAirportSecurity.

* The ''Pacific Surfliner'' is the busiest line in the West, from San Diego to [[{{Sideways}} San Luis Obispo]] by way of Los Angeles, and [[ShamelessSelfPromotion yes, tourists]], quite a lot of it runs right along the beach. Especially popular with military personnel, college students, and weekend vacationers.

* The ''Coast Starlight'' goes from Los Angeles to Seattle

* The ''Capitol Corridor'' is Northern California's answer to the Pacific Surfliner, running from San Jose to Auburn (and soon to Reno) by way of Oakland and Sacramento. Amtrak notably does not reach San Francisco. Popular with state officials.

* The ''Keystone Service'' from New York to Harrisburg via Philadelphia.
