89-533: The Amtrak Old Saybrook–Old Lyme Bridge ( Connecticut River Bridge ) is a railroad bridge that carries the Northeast Corridor over the Connecticut River between Old Saybrook and Old Lyme, Connecticut . It is the southernmost crossing of the river before it reaches Long Island Sound . The bridge is a truss bridge with a bascule span, allowing boat traffic to pass through. The bridge
178-585: A bascule bridge similar in size to the existing span, or a vertical lift bridge with possibly increased clearances. Either option would be built on a parallel alignment just south of the existing bridge. Fully high-level designs without movable sections were eliminated from consideration due to the massive approaches that would have to be built, which would have major impacts on nearby wetlands and increase construction and land acquisition costs. Construction staging plans were released in April 2020. Those plans call for

He took the term megalopolis from a small Greek town that was settled in the Classical Era with the hope it would "become the largest of the Greek cities". The city still exists today, but is largely a sleepy agricultural community. However, the dream of

Service with electric locomotives between New Haven and Boston began on January 31, 2000. The project took four years and cost close to $ 2.3 billion: $ 1.3 billion for the infrastructure improvements and close to $ 1 billion for both
534-406: A part of the line that hugs the shore of Long Island Sound . Some of these crossings constitute the only points of access to waterfront communities and businesses otherwise disconnected from the road network. As such, eliminating them would require grade separation to maintain access. Six of the grade crossings have four-quadrant gates with induction loop sensors, which allow vehicles stopped on

6497-463: The region. Among the world's 500 largest companies , 54 are based in the Northeast megalopolis. Among the 500 largest U.S.-based companies , 162 are headquartered in the region. The region is the center of the global hedge fund industry, which is heavily based in New York City and the suburban Connecticut cities of Greenwich and Stamford . The Northeast megalopolis is home to hundreds of colleges and universities, including several that rank among
6586-401: The rest of the strip. Additionally, the proximity to Europe, as well as the prominence of Ellis Island as an immigrant processing center, made New York City and cities nearby a "landing wharf for European immigrants," who represented an ever replenished supply of diversity of thought and determined workers. By contrast, the other major source of trans-oceanic immigrants was China , which
6675-514: The resulting outcry led to a push for electric operation in Manhattan . The NH announced in 1905 that it would electrify its main line from New York to Stamford, Connecticut . Along with the construction of Grand Central Terminal , which was opened in 1913, the NYC electrified its lines. On September 30, 1906, the NYC conducted a test of suburban multiple unit service to Highbridge station on
6764-471: The south to Boston in the north. The region is not uniformly populated between the terminal cities, and there are regions nominally within the corridor yet located away from the main transit lines that have been bypassed by urbanization, such as the Quiet Corner in Connecticut. The region accounts for 20% of the U.S. gross domestic product . It is home to two of the world's largest stock exchanges,
6853-614: The stage for later high-speed operation. NECIP also introduced the AEM-7 locomotive, which lowered travel times and became the most successful engine on the Corridor. The NECIP set travel time goals of 2 hours and 40 minutes between Washington and New York, and 3 hours and 40 minutes between Boston and New York. These goals were not met because of the low level of funding provided by the Reagan Administration and Congress in
6942-417: The title from the pre– Civil War industrial era until about 1929, and New York City has held it since. Loudoun and Fairfax County , Virginia are the wealthiest counties in the country, and Connecticut's Gold Coast has one of the highest population densities of families worth over $ 30 million USD. The concept of megalopolises originated with Jean Gottmann , a French geographer who wrote Megalopolis ,
7031-635: The tracks to be detected in time for an oncoming train to stop. The remaining five grade crossings, 3 near New London Union Station and two in Stonington, have dual gates. FRA rules limit track speeds on the corridor to 80 miles per hour (130 km/h) over conventional crossings and 95 miles per hour (153 km/h) over crossings with four-quadrant gates and vehicle detection tied into the signal system. Northeast megalopolis Core combined statistical areas (CSAs) Outlying metropolitan areas The Northeast megalopolis , also known as
7120-590: The way for Amtrak to buy sections of the NEC not already been sold to these commuter transportation authorities. These purchases by Amtrak were controversial at the time, and the Department of Transportation blocked the transaction and withheld purchase funds for several months until Amtrak granted it control over reconstruction of the corridor. In February 1975, the Preliminary System Plan for Conrail proposed to stop running freight trains on
7209-678: The way, were electrified in 1937 and 1938. The Potomac Yard retained its electrification until 1981. In the 1930s, PRR equipped the New York–Washington line with Pulse code cab signaling . Between 1998 and 2003, this system was overlaid with an Alstom Advanced Civil Speed Enforcement System (ACSES) , using track-mounted transponders similar to the Balises of the modern European Train Control System . The ACSES will enable Amtrak to implement positive train control to comply with
7298-401: The west. The region includes many of the nation's most populated metropolitan areas, including those of New York City , Philadelphia , Washington, D.C. , and Boston . As of 2020, it contained more than 50 million people, about 17% of the U.S. population on less than 2% of the nation's land area, with a population density of about 1,000 people per square mile (390 people/km ), far more than
7387-748: The world's most elite universities, including Harvard and MIT , both in Cambridge, Massachusetts , Brown in Providence, Rhode Island , Yale in New Haven, Connecticut , Columbia in New York City, Princeton in Princeton, New Jersey , the University of Pennsylvania in Philadelphia , Johns Hopkins in Baltimore , and Georgetown in Washington, D.C. Total GDP of Northeast megalopolis
7476-408: Was built in 1870 and rebuilt on the same piers in 1889. The old single-track bridge was no longer able to handle the train frequency and weights that the New Haven wished to run. Construction of the new bridge began in May 1905, and the substructure was completed in April 1906. The bridge was built with two-track spans, with the abutments long enough for a second set of spans should quadruple-tracking of
7565-554: Was complete. With the 1968 creation of Penn Central , which was a combination of those two railroads and the New York Central Railroad, the entire corridor was under the control of a single entity for the first time. After successor Penn Central’s 1970 bankruptcy, the corridor was almost entirely subsumed by the subsequently-created Amtrak on May 1, 1971. In 1899, William J. Wilgus , the New York Central Railroad (NYC)'s chief engineer, proposed electrifying
7654-575: Was done on April 9, 1933, for trains running west from Philadelphia, with the change point moved to Paoli. In 1933, the electrification south of Wilmington was stalled by the Great Depression , but the PRR got a loan from the Public Works Administration to resume work. The tunnels at Baltimore were rebuilt as part of the project. Electric service between New York and Washington began on February 10, 1935. On April 7,
7743-497: Was farther from the U.S. West Coast than Europe was from the East, and whose ethnicity made them targets of racial discrimination , creating barriers to their seamless integration into American society. By 1950, the region held over one-fifth of the total U.S. population, with a density nearly 15 times that of the national average. The region has been home to the richest city in the nation for over 200 years: Hartford, Connecticut held
7832-402: Was made the nation's capital. According to Gottmann, capital cities "will tend to create for and around the seats of power a certain kind of built environment, singularly endowed, for instance, with monumentality, stressing status and ritual, a trait that will increase with duration." The transportation and telecommunications infrastructure that the capital city mandated also spilled over into
7921-695: Was opposed by then-acting Amtrak president David Gunn . The plan, supported by the Bush administration, would "turn over the Northeast Corridor – the tracks from Washington to Boston that are the railroad's main physical asset – to a federal-state consortium." With the passage of the Passenger Rail Investment and Improvement Act of 2008 , the Congress established the Northeast Corridor Commission (NEC Commission) in
