The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly 1,609.344 metres.
High-speed rail (HSR) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above 250 km/h (155 mph) or upgraded lines in excess of 200 km/h (125 mph) are widely considered to be high-speed.
Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed, expressed as kilometres per hour (km/h) or miles per hour (mph) or both. Speed limits are commonly set by the legislative bodies of national or provincial governments and enforced by national or regional police and judicial authorities. Speed limits may also be variable, or in some places nonexistent, such as on most of the Autobahnen in Germany.
High Speed 1 (HS1), legally the Channel Tunnel Rail Link (CTRL), is a 109.9-kilometre (68.3-mile) high-speed railway linking London with the Channel Tunnel.
The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Manchester, Liverpool and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for 399 miles (642 km) and was opened from 1837 to 1881. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of 700 miles (1,127 km). The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh. However, the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Manchester, Liverpool and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns.
The Acela is Amtrak's flagship passenger train service along the Northeast Corridor (NEC) in the Northeastern United States between Washington, D.C., and Boston via 13 intermediate stops, including Baltimore, New York City and Philadelphia. Acela trains are the fastest in the Americas, reaching 150 miles per hour (240 km/h), but only over 49.9 miles (80.3 km) of the 457-mile (735 km) route.
Maglev is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
The British Rail Class 390 Pendolino is a type of electric high-speed passenger train operated by Avanti West Coast in the United Kingdom, leased from Angel Trains. They are electric multiple units using Fiat Ferroviaria's tilting train Pendolino technology and built by Alstom. Fifty-three units were originally built between 2001 and 2004 for operation on the West Coast Main Line (WCML). They were ordered as eight-car units, later extended to nine cars, of which some were then lengthened further to 11 cars. These new 11-car trains were renumbered as the subclass 390/1. The trains of the original batch were the last to be assembled at Alstom's Washwood Heath plant, before its closure in 2005. The remaining trains in the fleet were built in Italy.
The world record for a conventional wheeled passenger train is held by a modified French TGV high-speed code named V150, set in 2007 when it reached 574.8 km/h (357.2 mph) on a 140 km (87 mi) section of track. Japan's experimental maglev train L0 Series achieved 603 km/h (375 mph) on a 42.8 km magnetic levitation track in 2015. Under commercial traffic and practical conditions where trains carry passengers across from one station to another, the world records for top operating speeds of maglev and single phase trains are held respectively by China's Shanghai Maglev Train that has a top speed of 431 km/h and CR400 Fuxing Hao with 350 km/h, which also hails from China. They are followed by France's TGV Duplex and Japan's E5 series shinkansen which both have maximum operating speeds of 320 km/h for commercial services.
Metrication in the Republic of Ireland happened mostly in the 20th century and was officially completed in 2005, with a few exceptions.
In the United States, speed limits are set by each state or territory. States have also allowed counties and municipalities to enact typically lower limits. Highway speed limits can range from an urban low of 25 mph (40 km/h) to a rural high of 85 mph (137 km/h). Speed limits are typically posted in increments of five miles per hour (8 km/h). Some states have lower limits for trucks, some also have night and/or minimum speed limits.
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.
High-speed rail in the United Kingdom is provided on five upgraded railway lines running at top speeds of 125 mph (200 km/h) and one purpose-built high-speed line reaching 186 mph (300 km/h).
The Northern Lights Express (NLX) 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.
Brightline is an inter-city rail route in the United States that runs between Miami and Orlando, Florida. Part of the route runs on track owned and shared by the Florida East Coast Railway.
Higher-speed rail (HrSR), also known as high-performance rail, higher-performance rail, semi-high-speed rail or almost-high-speed rail, is the jargon used to describe inter-city passenger rail services that have top speeds of more than conventional rail but are not high enough to be called high-speed rail services. The term is also used by planners to identify the incremental rail improvements to increase train speeds and reduce travel time as alternatives to larger efforts to create or expand the high-speed rail networks.
Road signs used by countries in the Americas are significantly influenced by the Manual on Uniform Traffic Control Devices (MUTCD), first released in 1935, reflecting the influence of the United States throughout the region. Other non-American countries using road signs similar to the MUTCD include Australia, Indonesia, Ireland, Japan, Malaysia, New Zealand, and Thailand. They, along with the US Virgin Islands, are also the only countries listed here which drive on the left—with the exception of Liberia and the Philippines, both of which drive on the right.
Hyperloop One, known as Virgin Hyperloop until November 2022, was an American transportation technology company that worked to commercialize high-speed travel utilizing the Hyperloop concept which was a variant of the vacuum train. The company was established on June 1, 2014, and reorganized and renamed on October 12, 2017.
The William B. Umstead Bridge is a two-lane automobile bridge spanning the Croatan Sound, between Manns Harbor and Roanoke Island, in Dare County, North Carolina. The bridge carries US 64 and is utilized by local and seasonal tourist traffic. The bridge speed limit is 55 miles per hour (89 km/h), except during the months of July and August when it will drop to 20 miles per hour (32 km/h) during dusk and dawn; the west end of the bridge becomes home of more than hundred-thousand purple martins as they prepare for their annual migration to Brazil.
This is a comparison of road signs in countries and regions that speak majorly English, including major ones where it is an official language and widely understood.
