Commuter rail or suburban rail is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Commuter rail systems can use locomotive-hauled trains or multiple units, using electric or diesel propulsion. Distance charges or zone pricing may be used.
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU.
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.
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 400 miles (644 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 interurban is a type of electric railway, with tram-like electric self-propelled railcars which run within and between cities or towns. The term "interurban" is usually used in North America, with other terms used outside it. They were very prevalent in many parts of the world before the Second World War and were used primarily for passenger travel between cities and their surrounding suburban and rural communities. Interurban as a term encompassed the companies, their infrastructure, their cars that ran on the rails, and their service. In the United States, the early 1900s interurban was a valuable economic institution, when most roads between towns, many town streets were unpaved, and transportation and haulage was by horse-drawn carriages and carts.
InterCity is the classification applied to certain long-distance passenger train services in Europe. Such trains generally call at major stations only.
The Polish State Railways is a Polish state-owned holding company comprising the rail transport holdings of the country's formerly dominant namesake railway operator. The company was reformed in 2001 when the former Polish State Railways state-owned enterprise was divided into several units based on the need for separation between infrastructure management and transport operations. Polish State Railways is the dominant company in the PKP Group collective that resulted from the split, and maintains 100% share control, being fully responsible for the assets of all of the other PKP Group component companies.
The Italian railway system is one of the most important parts of the infrastructure of Italy, with a total length of 24,567 km (15,265 mi) of which active lines are 16,832 km (10,459 mi). The network has recently grown with the construction of the new high-speed rail network. Italy is a member of the International Union of Railways (UIC). The UIC Country Code for Italy is 83.
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas:
Rail transportation in the United States consists primarily of freight shipments along a well integrated network of standard gauge private freight railroads that also extend into Canada and Mexico. The United States has the largest rail transport network of any country in the world, about 160,000 miles (260,000 km).
An intercity bus service or intercity coach service, also called a long-distance, express, over-the-road, commercial, long-haul, or highway bus or coach service, is a public transport service using coaches to carry passengers significant distances between different cities, towns, or other populated areas. Unlike a transit bus service, which has frequent stops throughout a city or town, an intercity bus service generally has a single stop at one location in or near a city, and travels long distances without stopping at all. Intercity bus services may be operated by government agencies or private industry, for profit and not for profit. Intercity coach travel can serve areas or countries with no train services, or may be set up to compete with trains by providing a more flexible or cheaper alternative.
Rail transport in Japan is a major means of passenger transport, especially for mass and high-speed travel between major cities and for commuter transport in urban areas. It is used relatively little for freight transport, accounting for just 0.84% of goods movement. The privatised network is highly efficient, requiring few subsidies and running with extreme punctuality, though since privatisation several unprofitable but socially valuable lines have been closed by private operators.
PKP Intercity is the subsidiary of the PKP Group responsible for long-distance rail passenger transport in Poland. It operates around 350 trains daily, connecting large agglomerations and smaller towns in Poland. It offers its services under TLK, InterCity, Express Intercity and Express Intercity Premium brands. The company also provides most international rail connections to and from the country. In 2023, the company reported an 18.2% of market share in terms of total number of served passengers in the country.
Passenger rail transport is one of the principal means of transport in the People's Republic of China, with rail passenger traffic exceeding 1.86 billion railway trips in 2011. It is operated by the China Railway Corporation (CR). The Spring Festival Travel Season is the peak railway travel season of the year.
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).
A limited express is a type of express train or express bus service that stops at fewer locations compared to other express services on the same or similar routes.
A passenger train is a train used to transport people along a railroad line. These trains may consist of unpowered passenger railroad cars hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars. Passenger trains stop at stations or depots, where passengers may board and disembark. In most cases, passenger trains operate on a fixed schedule and have priority over freight trains.
Railway companies in Europe assign their trains to different categories or train types depending on their role. Passenger trains may be broadly split into long-distance and local trains; the latter having average journey times of under an hour and a range of less than 50 kilometres. Goods trains have their own train types. The names of these train types have changed continually over the course of time.
A quadruple-track railway is a railway line consisting of four parallel tracks with two tracks used in each direction. Quadruple-track railways can handle large amounts of traffic, and so are used on very busy routes or sections. Such conversion is referred to as "quadruplication".
Intercity, often shortened to IC, is the second-highest train classification in Germany, after the Intercity Express (ICE). Intercity services are locomotive-hauled express trains, usually over long-distances. There are Intercity routes throughout Germany and routes generally operate every other hour, with multiple routes giving a more frequent service on core routes. Intercity services are operated by the DB Fernverkehr division of Deutsche Bahn, Germany’s national railway.
