The Corridor Identification and Development Program, abbreviated as the Corridor ID Program, is a comprehensive planning program for inter-city passenger rail projects in the United States administered by the Federal Railroad Administration (FRA) under the 2021 Infrastructure Investment and Jobs Act (IIJA). Each route accepted into the program is granted $500,000 toward planning activities and is prioritized for future federal funding.
As of December 2023 [update] , a total of 69 passenger rail corridors have been accepted into the Corridor ID Program. Of these, 7 are new high-speed rail routes, 34 are new conventional rail routes, 13 are existing routes with proposed extensions, and 15 are existing routes with proposed upgrades. For example, accepted projects include Brightline West high-speed rail, the Northern Lights Express from Minneapolis to Duluth, the Heartland Flyer extension from Oklahoma City to Newton, and frequency increases for the Cardinal and Sunset Limited .
The $1.8 billion Corridor ID Program was authorized by Congress with the passage of the IIJA in November 2021 and was formally established in May 2022. [1] [2] The FRA began soliciting its first round of applications in December 2022 [3] and made its first selection of 69 corridors in December 2023. [4]
The purpose of the Corridor ID Program is to identify potential passenger rail expansion projects and to provide seed funding for planning stages. Construction and operational funding are not included. Eligible entities are invited to submit projects for consideration. Such entities include Amtrak, regional rail authorities, states, groups of state, state subdivisions, regional planning organizations, and federally recognized tribes. [1] Once selected, each corridor is initially granted $500,000 toward project planning activities. Projects proceed through three steps:
This list is current as of December 2023 [update] . A total of 69 passenger rail corridors spanning 44 states have been accepted into the Corridor ID Program.

The Northeast Regional service received more than $787.7 million in gross ticket revenue in FY 2023.
The Pennsylvanian is a 444-mile (715 km) daily daytime Amtrak train running between New York City and Pittsburgh via Philadelphia. The trains travel across the Appalachian Mountains, through Pennsylvania's capital Harrisburg, the Pennsylvania Dutch Country, suburban and central Philadelphia, and New Jersey en route to New York. The entire train ride takes about 9 hours total: 1.5 hours between New York and Philadelphia, 2 hours between Philadelphia and Harrisburg, and 5.5 hours between Harrisburg and Pittsburgh.
The Hiawatha Service, or simply Hiawatha, is an 86-mile (138 km) train route operated by Amtrak on the western shore of Lake Michigan between Chicago, Illinois, and Milwaukee, Wisconsin. However, the name was historically applied to several different routes that extended across the Midwest and to the Pacific Ocean. As of 2007, twelve to fourteen trains ran daily between Chicago and Milwaukee, making intermediate stops in Glenview, Illinois; Sturtevant, Wisconsin; and Milwaukee Mitchell International Airport. The line is partially supported by funds from the state governments of Wisconsin and Illinois. The line utilizes the CPKC Railway's C&M Subdivision and Metra's Milwaukee District North Line.
The Cardinal is a long-distance passenger train operated by Amtrak between New York Penn Station and Chicago Union Station via Philadelphia, Washington, D.C., Charlottesville, Charleston, Huntington, Cincinnati, and Indianapolis. Along with the Capitol Limited and Lake Shore Limited, it is one of three trains linking the Northeast and Chicago. Its 1,146-mile (1,844 km) trip between New York and Chicago takes 281⁄4 hours.
The Heartland Flyer is a daily passenger train that follows a 206-mile (332 km) route between Oklahoma City, Oklahoma, and Fort Worth, Texas. It is operated by Amtrak and jointly funded by the states of Oklahoma and Texas.
The North Coast Hiawatha was a long-distance passenger train operated by Amtrak between Chicago, Illinois, and Seattle, Washington.
The Southeast Corridor (SEC) is a proposed passenger rail transportation project in the Mid-Atlantic and Southeastern United States to extend high-speed passenger rail services from the current southern terminus of the Northeast Corridor in Washington, D.C.. Routes would extend south via Richmond and Petersburg, Virginia, with a spur to Norfolk in Virginia's Hampton Roads region; the mainline would continue south to Raleigh, Durham, Greensboro, and Charlotte, North Carolina. Since the corridor was first established in 1992, the U.S. Department of Transportation (USDOT) has extended it further to Atlanta, Georgia and Macon, Georgia; Greenville, South Carolina; Columbia, South Carolina; Jacksonville, Florida; and Birmingham, Alabama.
Plans for high-speed rail in the United States date back to the High-Speed Ground Transportation Act of 1965. Various state and federal proposals have followed. Despite being one of the world's first countries to get high-speed trains, it failed to spread. Definitions of what constitutes high-speed rail vary, including a range of speeds over 110 mph (180 km/h) and dedicated rail lines. Inter-city rail with top speeds between 90 and 125 mph is sometimes referred to in the United States as higher-speed rail.
Front Range Passenger Rail is a proposed inter-city passenger train service along the Front Range and broader I-25 corridors in Colorado and Wyoming. Most proposals envision a route from Pueblo north to Colorado Springs, Denver, Boulder, and Fort Collins. Extensions north to Cheyenne and south to Trinidad, Albuquerque, and even El Paso have been discussed.
The Hartford Line is a commuter rail service between New Haven, Connecticut, and Springfield, Massachusetts, using the Amtrak-owned New Haven–Springfield Line. The project is a joint venture between the states of Connecticut and Massachusetts, with support from the federal government as well. CT Rail-branded trains provide service along the corridor, and riders can use Hartford Line tickets to travel on board most Amtrak trains along the corridor at the same prices. The service launched on June 16, 2018.
The Northern Lights Express (NLX) project is a planned higher-speed rail service that would run 155 miles (249 km) between Minneapolis and Duluth primarily in the U.S. state of Minnesota. A portion of the proposed line would run through neighboring Wisconsin to serve Duluth's "Twin Port" of Superior. Plans are to upgrade an existing BNSF Railway freight line to allow trains to travel at up to 90 miles per hour (145 km/h). The train service is said to provide an alternative to traveling Interstate 35 between Duluth and the Twin Cities or to other destinations along the line such as the casino in Hinckley.
The Missouri River Runner is a 283-mile (455 km) passenger train service operated by Amtrak in Missouri between Gateway Transportation Center in St. Louis and Union Station in Kansas City. The eastern half of the route runs largely along the right bank of the Missouri River.
The Gulf Coast Limited was a passenger train service operated by Amtrak along the Gulf Coast of the United States. It ran daily between New Orleans, Louisiana, and Mobile, Alabama, with stops in Bay St. Louis, Gulfport, Biloxi, and Pascagoula, Mississippi. The route first operated in 1984–1985, and again in 1996–1997.
The Hilltopper was a passenger train operated by Amtrak in the Mid-Atlantic region of the United States. It ran daily from South Station in Boston, Massachusetts to Catlettsburg station in Catlettsburg, Kentucky. The 1,674 mi (2,694 km) run made 34 stops in 11 states and the District of Columbia.
The Quad Cities is a planned Amtrak Illinois Service intercity passenger train that will operate between Chicago and Moline in the US state of Illinois.

On the Wyanet–Moline segment, which will include a station at Geneseo, the train will use track owned by Iowa Interstate Railroad.
NC By Train is a brand name used by the Rail Division of the North Carolina Department of Transportation (NCDOT) for two state-supported Amtrak routes operating in the U.S. state of North Carolina–the Carolinian and the Piedmont.
Coachella Valley–San Gorgonio Pass Rail Corridor Service is an effort by the Riverside County Transportation Commission (RCTC) to start regular passenger rail services between Los Angeles and Indio, California. Service is envisioned to start at Los Angeles Union Station and run over the route of the Southwest Chief, switching to the valley's Union Pacific Railroad line at Colton to run over San Gorgonio Pass and terminating at Indio or Coachella. The proposed schedule would include one morning and one afternoon trip in each direction for two daily round trips. As of 2022, the current rail line in the Coachella Valley is owned by the Union Pacific Railroad, as part of its Sunset Route between Los Angeles and Yuma, Arizona. The Sunset Limited Amtrak service stops at the Palm Springs station three times a week in each direction.
The Borealis, referred to as Twin Cities–Milwaukee–Chicago (TCMC) during planning, is an Amtrak inter-city rail service that operates daily between Chicago, Illinois, and Saint Paul, Minnesota, via Milwaukee, Wisconsin. The first service began on May 21, 2024, under the Amtrak Midwest brand.
New Orleans–Baton Rouge passenger rail is a proposed inter-city passenger train service between New Orleans and Baton Rouge along the I-10 corridor in the U.S. state of Louisiana. The route would connect the state's largest city to its second-largest city and state capital with trains as fast as 90 mph (140 km/h).
