New Jersey Transit Corporation, branded as NJ Transit or NJTransit and often shortened to NJT, is a state-owned public transportation system that serves the U.S. state of New Jersey and portions of the state of New York and Pennsylvania. It operates bus, light rail, and commuter rail services throughout the state, connecting to major commercial and employment centers both within the state and in its two adjacent major cities, New York City and Philadelphia. In 2022, the system had a ridership of 175,960,600.
FasTracks is a multibillion-dollar public transportation expansion plan under construction in metropolitan Denver, Colorado, United States. Developed by the Regional Transportation District (RTD), the plan consists of new commuter rail, light rail, and express bus services. Six new light rail, electric commuter rail and diesel commuter rail lines with a combined length of 122 miles (196 km) will be constructed under the plan. It expands on previous transportation projects, notably T-REX, and includes 57 new transit stations and stops, 21,000 new parking spaces, 18 miles (29 km) of a bus service between Denver and Boulder and the renovation of Denver Union Station as a multi-modal transportation hub.
The North–South Rail Link (NSRL) is a proposed rail tunnel, or pair of tunnels, that would connect North Station and South Station in downtown Boston, Massachusetts. The project would build new underground stations near the existing stations, connect them with about 1.5 miles (2.4 km) of tunnels, and add other tunnels to link up with existing surface tracks.
The Urban Ring was a proposed project of the Massachusetts Bay Transportation Authority and the Massachusetts Department of Transportation, to develop new public transportation routes that would provide improved circumferential connections among many existing transit lines that project radially from downtown Boston. The Urban Ring Corridor is located roughly one to two miles from downtown Boston, passing through the Massachusetts cities of Boston, Chelsea, Everett, Medford, Somerville, Cambridge, and Brookline. The project was expected to convert 41,500 car trips to transit trips daily.
The Keystone Corridor is a 349-mile (562 km) railroad corridor between Philadelphia and Pittsburgh, Pennsylvania, that consists of two rail lines: Amtrak and SEPTA's Philadelphia-to-Harrisburg main line, which hosts SEPTA's Paoli/Thorndale Line commuter rail service, and Amtrak's Keystone Service and Pennsylvanian inter-city trains; and the Norfolk Southern Pittsburgh Line. The corridor was originally the Main Line of the Pennsylvania Railroad.
Schuylkill River Passenger Rail is a proposed passenger train service along the Schuylkill River between Philadelphia and Reading, Pennsylvania, with intermediate stops in Norristown, King of Prussia, Phoenixville, and Pottstown.
Capital Area Transit (CAT), also known as rabbittransit Capital Region, is a regional public transportation agency that operates bus and paratransit service in the Harrisburg–Carlisle metropolitan statistical area. Its scheduled route bus service covers much of the southern half of Dauphin County and the eastern half of Cumberland County. It also operates two bus routes into northern York County. CAT's shared ride/paratransit operations serve residents throughout Dauphin County. In 2022, the system had a ridership of 1,200,800.
The Northern Branch Corridor Project is a proposed extension of the Hudson-Bergen Light Rail (HBLR) from its northern terminus into eastern Bergen County, New Jersey, initially proposed in 2001. If built, the new service would use the right-of-way of the Northern Branch on which the Erie Lackawanna Railroad ran passenger service until October 3, 1966, and is currently a lightly used, stub-ended freight rail line owned by CSX Transportation. The Northern Branch Corridor is at the foot of the west side of the Hudson Palisades in the Hackensack River valley, running for much of its length parallel to Overpeck Creek. After mixed reactions and extensive community input to a draft environmental impact statement (EIS), it was decided in 2013 to terminate the line at the Englewood Hospital and Medical Center. In March 2017 the Supplementary Draft Environmental Impact Statement was approved by the Federal Transit Administration allowing for a period of public reaction. A separately-conceived and funded bridge at 69th St. in North Bergen, necessary for operation of the system, has been completed. In 2017 NJ Transit estimated that the line would open in 2029.
The Harrisburg–Carlisle metropolitan statistical area, officially the Harrisburg–Carlisle, PA Metropolitan Statistical Area, and also referred to as the Susquehanna Valley, is defined by the Office of Management and Budget as an area consisting of three counties in South Central Pennsylvania, anchored by the cities of Harrisburg and Carlisle.
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. The Main Line is part of the longer Keystone Corridor, which continues west to Pittsburgh along the Norfolk Southern Railway's Pittsburgh Line. This section is sometimes referred to as "Keystone East" and is part of Amtrak's Keystone Service.
There are several passenger rail projects being discussed in Minnesota. There is one existing commuter rail service in the state, the Northstar Line, and one existing long-distance intercity rail service, the Empire Builder. Future projects include a mixture of short-distance commuter rail and medium-distance regional rail lines which would run from the Twin Cities outward to neighboring states and perhaps Canada.
Ann Arbor–Detroit Regional Rail is a planned regional rail link along the Michigan Line between the cities of Ann Arbor and Detroit, Michigan, a total length of 39.72 miles (63.92 km). The project would connect with a proposed Detroit bus rapid transit service and the QLine streetcar.
The I-77 Bus Rapid Transit is a proposed bus rapid transit (BRT) service, connecting the towns northern Mecklenburg and southern Iredell counties to Uptown Charlotte, North Carolina. The BRT replaces the previously planned commuter rail service, the Lynx Red Line, that was routed along the existing Norfolk Southern O-Line right-of-way. However, several issues had arisen that included ineligibility for federal funding and Norfolk Southern refusal to allow access to its right-of-way. In 2019, after a reevaluation of the entire corridor, the Charlotte Area Transit System (CATS) decided to move forward with BRT and shelve the commuter rail; which had been met with frustration by various city leaders and residents impacted by it.
The Dan Patch Corridor is a proposed commuter rail line that would serve a region which runs from Minneapolis to Northfield, Minnesota. The corridor consists of the tracks on the former Minneapolis St. Paul Rochester and Dubuque Electric Traction Company lines, which came to be known as the Dan Patch lines. It was proposed as a passenger rail line in 2000 after being identified as a "Tier One" corridor in the Minnesota Department of Transportation's 2000 Commuter Rail System Plan before being given a study ban during the 2002 Minnesota legislative session. It sat in relative silence until 2008, when bills were introduced in the Minnesota State Legislature to potentially revive discussion. On May 21, 2023, the Minnesota House of Representatives and Minnesota Senate passed an omnibus transit bill that removed the study ban for the Dan Patch line.
Based in southwest Ohio, the Eastern Corridor Program is a regional effort that integrates roadway network improvements, new rail transit, expanded bus service, bikeways and walking paths to improve travel and access between Greater Cincinnati's eastern communities and its central employment, economic and social centers. The Program is designed to address the long-standing transportation needs of the region and to provide additional opportunity for community enhancement, economic development and regional growth.
The Paoli/Thorndale Line, commonly known as the Main Line, is a SEPTA Regional Rail service running from Center City Philadelphia through Montgomery County and Delaware County to Thorndale in Chester County. It operates along the far eastern leg of Amtrak's Philadelphia to Harrisburg Main Line, which in turn was once the Main Line of the Pennsylvania Railroad and is now part of the Keystone Corridor, a federally-designated high-speed rail corridor.
There is a current proposal to bring commuter rail service to the Phoenix metropolitan area.
The Dumbarton Rail Corridor is a proposed transbay passenger rail line which would reuse the right-of-way that was initially constructed from 1907–1910 as the Dumbarton Cut-off. The Dumbarton Cut-off includes the first structure to span San Francisco Bay, the 1910 Dumbarton Rail Bridge, although the vintage Cut-off bridges would likely be replaced prior to activating new passenger service. Dumbarton Rail Corridor would provide service between Union City in the East Bay and Menlo Park on the Peninsula, with train service continuing to both San Francisco and San José along the existing Caltrain tracks. It has been in the planning stages since 1988, and would be the first above-ground transbay rail line since Key System electric trains stopped running on the lower deck of the Bay Bridge in 1958, and the first new transbay crossing of any kind since the completion of the Transbay Tube in 1974.
The Downtown Rail Extension (DTX) is a planned second phase of the San Francisco Transbay Transit Center (TTC). When complete, it will extend the Caltrain Peninsula Corridor commuter rail line from its current northern terminus at 4th and King via a 1.3 mi (2.1 km) tunnel. The new terminus will be near the Financial District and will provide intermodal connections to BART, Muni, Transbay AC Transit buses, and long-distance buses. In addition, the California High Speed Rail Authority (CHSRA) plans to use DTX and the Caltrain-owned Peninsula Corridor for service on the CHSRA San Francisco–San Jose segment. Because DTX uses a long tunnel, current diesel locomotives are not suitable and the Caltrain Modernization Project (CalMod), which includes electrification of the line and acquisition of electrified rolling stock, is a prerequisite.
The Monterey County Rail Extension is a planned commuter rail extension that would bring Caltrain passenger service south of its existing Gilroy, California terminus to Salinas in Monterey County, using the existing Coast Line owned by Union Pacific (UPRR). Implementation of the rail extension will occur over three phases, starting from Salinas and moving north. When construction is complete, there will be four trains operated over the extended line per weekday: two northbound trains that depart from Salinas and travel to San Francisco in the morning, and two southbound trains that return to Salinas in the afternoon.
