Amtrak operates two types of long-distance trains: single-level and bi-level. Due to height restrictions on the Northeast Corridor, all six routes that terminate at New York Penn Station operate as single-level trains with Amfleet coaches and Viewliner sleeping cars. The remaining nine long-distance routes operate as bi-level trains with Superliner coaches and sleeping cars. Both single-level and bi-level trains are equipped with Viewliner baggage cars. Amtrak plans to replace all of its long-distance rail cars by 2032, except for the Viewliner II fleet.^[8]

Long-distance trains are typically hauled by GE Genesis diesel locomotives. Trains which traverse the Northeast Corridor use Siemens ACS-64 electric locomotives for that segment of their routes, switching engines at Washington Union Station. Amtrak is in the process of replacing all of its long-distance locomotives with diesel-electric Siemens Charger units by 2032.^[8] In 2022 the Empire Builder became the first route to receive the new locomotives.^[9]

Dividing trains

In a practice not seen elsewhere in the Amtrak network, four long-distance trains divide partway along their routes. This allows trains to serve multiple endpoints without requiring passengers to transfer, and provides efficiency over the shared route segments.

Westbound from Chicago the Empire Builder divides at Spokane, with sections to Seattle and Portland. Eastbound from Chicago the Lake Shore Limited divides at Albany–Rensselaer, with sections to New York and Boston. The Texas Eagle and Sunset Limited are combined between Los Angeles and San Antonio, where the Texas Eagle continues to Chicago and the Sunset Limited to New Orleans. On the reverse trips the trains are coupled at these stations.

Baggage, bicycles, and pets

All long-distance Amtrak trains have checked baggage service, save for the Auto Train, which instead allows passengers to transport items in their vehicles. On every other route, passengers are allowed two personal items, two carry-on bags, and two free checked bags. Two additional bags, oversized bags, and bicycles may be checked for a fee. However, baggage and bikes cannot be checked at certain unstaffed stations.^{[10][11][12][13]}

Small dog and cats are allowed in carriers aboard long-distance routes for an additional fee, though only for trips shorter than seven hours (thus excluding the non-stop Auto Train). Service animals are not considered pets and are exempt from these restrictions. Animals cannot be checked as baggage.^[14]

Dining

All long-distance routes offer café service to both coach and sleeping car passengers. Café offerings include takeaway meals, snacks, hot beverages, soft drinks, and alcohol.^[15] As of 2023, sleeping car passengers also have access to one of two types of restaurant-style dining. Traditional Dining is available on eight routes and consists of full table service in a dining car. Six routes instead feature Flexible Dining, where passengers may order hot meals to be delivered to their room or lounge.^[16][17] Passengers may also bring their own food and drink.^[18]

Wi-Fi and cell service

Amtrak provides free basic Wi-Fi on seven of its long-distance routes: the Auto Train, Cardinal, Crescent, Lake Shore Limited, Palmetto, Silver Meteor, and Silver Star. The service is intended to support low-bandwidth uses only.^[19] Onboard internet is dependent on cell towers along the route of the train, so speed and availability correspond to regional cell coverage. Amtrak Wi-Fi aggregates signals from multiple wireless carriers and tends to be more reliable than personal mobile phone connections.^[20]

Major route changes

1970s

In Amtrak's first year, 1971, it significantly overhauled the long-distance rail network in the United States. In addition to selecting which existing routes to retain, Amtrak created several new routes: the Coast Starlight, North Coast Hiawatha, and Lake Shore. It also renamed several routes: the Spirit of St. Louis became the National Limited, the City of New Orleans the Panama Limited, and the South Wind the Floridian. The following year, 1972, the City of San Francisco was renamed the San Francisco Zephyr and the Lake Shore was discontinued.

The North Coast Hiawatha (1971–1979) at Bozeman Pass en route to Billings

The Inter-American entered service in 1973 as short-distance train between Laredo and Fort Worth. It was extended north to St. Louis in 1974 and further to Chicago in 1976. In 1974 Amtrak renamed the Super Chief to the Southwest Limited and the Texas Chief to the Lone Star following the Atchison, Topeka and Santa Fe Railway revoking permission to use the "Chief" names.

The Mountaineer and Lake Shore Limited began service in 1975, and the Palmetto in 1976. The Mountaineer lasted only until 1977, at which point it was replaced by the Hilltopper. The Pioneer also entered service in 1977, and the James Whitcomb Riley was renamed the Cardinal.

1979 was a year of major restructuring. Six long-distance routes were discontinued by the Carter Administration for not meeting a minimum farebox recovery ratio: the Lone Star, Champion, North Coast Hiawatha, National Limited, Floridian, and Hilltopper. As limited compensation, a Houston section was added to the Inter-American, a St. Petersburg section to the Silver Meteor, and the Empire Builder was rerouted to St. Cloud.^[24]: 38 Meanwhile, the Southern Railway transferred its last remaining passenger route, the Southern Crescent, to Amtrak, who renamed it the Crescent. The Desert Wind also entered service in 1979.

1980s

In 1981 the Capitol Limited began service, while the Inter-American was truncated to San Antonio, stripped of its Houston section, and renamed the Eagle. The Empire Builder was rerouted to Wenatchee, bypassing the Yakima Valley, while a Portland section was added. The Panama Limited was renamed back to the City of New Orleans in hopes of capitalizing on the song of the same name.

The Denver and Rio Grande Western Railroad opted-in to Amtrak in 1983. As a result, Amtrak rerouted its San Francisco Zephyr over the former route of the D&RGW's Rio Grande Zephyr between Denver and Salt Lake City, renaming the train the California Zephyr. Amtrak also began operating the Auto Train in 1983.

In 1984 Amtrak renamed the Southwest Limited to the Southwest Chief alongside the deployment of Superliner equipment, and also initiated the River Cities as a section of the City of New Orleans. In 1988 the Eagle was renamed the Texas Eagle, and in 1989 Amtrak began the Gulf Breeze as a section of the Crescent.

1990s

In 1990 the Capitol Limited and Broadway Limited were rerouted between Pittsburgh and Chicago, bypassing Fort Wayne. The Capitol Limited was moved to serve Cleveland and South Bend, the Broadway Limited to Youngstown and Akron.

The Desert Wind (1979–1997) at Cajon Pass en route from Las Vegas in 1991

Amtrak extended the Sunset Limited east to Florida in 1993, creating its only coast-to-coast route. The River Cities was discontinued the same year.

Amtrak discontinued the Tampa section of the Silver Meteor in 1994.

In 1995 Amtrak discontinued the Gulf Breeze, Palmetto, and Broadway Limited, the latter being partially replaced with the short-distance Three Rivers. Meanwhile, the City of New Orleans was rerouted west to Greenwood between Memphis and Jackson.

In 1996 the Three Rivers was extended to Chicago and the Silver Palm was introduced, essentially restoring service on the routes of the Broadway Limited and Palmetto that had ended the prior year. The Sunset Limited was rerouted to bypass Phoenix at the request of Union Pacific.

In 1997, funding issues forced Amtrak to discontinue the Desert Wind and Pioneer, severing Las Vegas, Wyoming, and Southern Idaho from the rail network.^[25]

2000s

The Three Rivers (1995–2005) rounding Horseshoe Curve in 2002

The Silver Palm was renamed to Palmetto in 2002, restoring the route's former name. In 2005 the Three Rivers was discontinued following the cancellation of a related Postal Service contract. That same year, the Sunset Limited was suspended east of New Orleans due to track damage from Hurricane Katrina.

Long-Distance Service Study

In November 2021 Congress passed the Infrastructure Investment and Jobs Act. Section 22214 of the law orders the Federal Railroad Administration (FRA) to study the restoration of all long-distance Amtrak routes that had been discontinued, daily service on non-daily trains (the Cardinal and Sunset Limited), and the possibility of new long-distance routes—particularly those that were discontinued upon the formation of Amtrak.^[28]

Work on the Long-Distance Service Study began in September 2022.^[29] Materials published in February 2023 indicated that the FRA is studying 18 discontinued long-distance Amtrak routes, as well as four that were discontinued in 1971: the City of Miami, George Washington, Pan-American, and San Francisco Chief.^[30]
