The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility.
Transportation in the United States is facilitated by road, air, rail, and waterways. The vast majority of passenger travel occurs by automobile for shorter distances, and airplane for longer distances. In descending order, most cargoes travel by railroad, truck, pipeline, or boat; air shipping is typically used only for perishables and premium express shipments. Transportation is the largest source of greenhouse gas emissions by the United States.
The National Railroad Passenger Corporation, doing business as Amtrak, is the national passenger railroad company of the United States. It operates inter-city rail service in 46 of the 48 contiguous U.S. States and nine cities in Canada. Amtrak is a portmanteau of the words America and trak, the latter itself a sensational spelling of track.
The Staggers Rail Act of 1980 is a United States federal law that deregulated the American railroad industry to a significant extent, and it replaced the regulatory structure that had existed since the Interstate Commerce Act of 1887.
The Railroad Revitalization and Regulatory Reform Act of 1976, often called the "4R Act," is a United States federal law that established the basic outlines of regulatory reform in the railroad industry and provided transitional operating funds following the 1970 bankruptcy of Penn Central Transportation Company. The law approved the "Final System Plan" for the newly created Conrail and authorized acquisition of Northeast Corridor tracks and facilities by Amtrak.
The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New Haven, Stamford, New York City, Philadelphia, Wilmington, and Baltimore to Washington, D.C. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States both by ridership and by service frequency as of 2013. The NEC carries more than 2,200 trains daily.
The Safety Appliance Act is a United States federal law that made air brakes and automatic couplers mandatory on all trains in the United States. It was enacted on March 2, 1893, and took effect in 1900, after a seven-year grace period. The act is credited with a sharp drop in accidents on American railroads in the early 20th century.
The Washington Metropolitan Area Transit Authority, commonly referred to as Metro, is a tri-jurisdictional government agency that operates transit service in the Washington metropolitan area. WMATA was created by the United States Congress as an interstate compact between Washington, D.C., the State of Maryland, and the Commonwealth of Virginia.
The Federal Railroad Administration (FRA) is an agency in the United States Department of Transportation (DOT). The agency was created by the Department of Transportation Act of 1966. The purpose of the FRA is to promulgate and enforce rail safety regulations, administer railroad assistance programs, conduct research and development in support of improved railroad safety and national rail transportation policy, provide for the rehabilitation of Northeast Corridor rail passenger service, and consolidate government support of rail transportation activities.
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.
Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving safely and to stop them when they are not.
The 2008 Chatsworth train collision occurred at 4:22:23 p.m. PDT on September 12, 2008, when a Union Pacific freight train and a Metrolink commuter train collided head-on in the Chatsworth neighborhood of Los Angeles, California, United States.
Rail speed limits in the United States are regulated by the Federal Railroad Administration. Railroads also implement their own limits and enforce speed limits. Speed restrictions are based on a number of factors including curvature, signaling, track condition, and the presence of grade crossings. Like road speed limits in the United States, speed limits for tracks and trains are measured in miles per hour (mph).
Dark territory is a term used in the North American railroad industry to describe a section of running track not controlled by signals. Train movements in dark territory were previously handled by timetable and train order operation, but since the widespread adoption of two way radio communications these have been replaced by track warrants and direct traffic control, with train dispatchers managing train movements directly. Today most dark territory consists of lightly used secondary branch lines and industrial tracks with speeds ranging between 25 miles per hour (40 km/h) and 40 miles per hour (64 km/h); however, there do exist a small minority of main lines that fall into the category.
The Michigan Line, sometimes known as the Chicago–Detroit Line, is a railroad corridor that runs from Porter, Indiana, to Dearborn, Michigan. It carries Amtrak's Blue Water and Wolverine services, as well as the occasional local and/or unit train operated by Norfolk Southern.
On February 16, 1996, a MARC commuter train collided with Amtrak's Capitol Limited passenger train in Silver Spring, Maryland, United States, killing three crew and eight passengers on the MARC train; a further eleven passengers on the same train and fifteen passengers and crew on the Capitol Limited were injured. Total damage was estimated at $7.5 million.
On the morning of December 1, 2013, a Metro-North Railroad Hudson Line passenger train derailed near the Spuyten Duyvil station in the New York City borough of the Bronx. Four of the 115 passengers were killed and another 61 injured; the accident caused $9 million worth of damage. It was the deadliest train accident within New York City since a 1991 subway derailment in Manhattan, and the first accident in Metro-North's history to result in passenger fatalities. The additional $60 million in legal claims paid out as of 2020 have also made it the costliest accident in Metro-North's history.
On May 12, 2015, an Amtrak Northeast Regional train from Washington, D.C. bound for New York City derailed and wrecked on the Northeast Corridor near the Kensington neighborhood of Philadelphia, Pennsylvania. Of 238 passengers and 5 crew on board, 8 were killed and over 200 injured, 11 critically. The train was traveling at 102 mph (164 km/h) in a 50 mph (80 km/h) zone of curved tracks when it derailed.
The Point Defiance Bypass is a 14.5-mile-long (23.3 km) rail line between the cities of DuPont and Tacoma in Pierce County, Washington. It was originally built by the Northern Pacific Railway – the Tacoma–Lakewood segment in 1874 as part of the Prairie Line, and the Lakewood–DuPont section in 1891. Passenger service on the lines declined after the 1914 completion of a flatter route along Puget Sound, and ended entirely in 1956.
On June 27, 2022, the Southwest Chief, a passenger train operated by Amtrak, derailed near the small town of Mendon, Missouri. The derailment was caused by the train striking a dump truck that was obstructing the crossing of County Road 113, about three miles (4.8 km) southwest of Mendon. Four people were killed in the wreck: three passengers on board the train and the truck driver, with up to 150 people injured.
