Passenger train in the context of "Acela"

A train station, railroad station, or railway station is a railway facility where trains stop to load or unload passengers, freight, or both. It generally consists of at least one platform, one track, and a station building providing such ancillary services as ticket sales, waiting rooms, and baggage/freight service. Stations on a single-track line often have a passing loop to accommodate trains travelling in the opposite direction.

Locations at which passengers only occasionally board or leave a train, sometimes consisting of a short platform and a waiting area but sometimes indicated by no more than a sign, are variously referred to as "stops", "flag stops", "halts", or "provisional stopping places". The stations themselves may be at ground level, underground, or elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams, or other rapid transit systems.

An express train is a type of passenger train that makes few or no stops between its origin and destination stations, usually major destinations, providing faster service than local trains that stop at many or all of the stations along their route. They are sometimes referred to by terms such as "fast train" or "high-speed train", e.g. the German Schnellzug. Though many high-speed rail services are express, not all trains described as express have been much faster than other services; trains in the United Kingdom in the 19th century were called expresses as long as they had a "journey speed" of at least 40 miles per hour (64 km/h). Express trains sometimes have higher fares than other routes, and bearers of a rail pass may be required to pay an extra fee. First class may be the only one available.Some express train routes that overlap with local train service may stop at stations near the tail ends of the line. This can be done, for example, where there is no supplemental local service to those stations. Express train routes may also become local at times when ridership is not high enough to justify parallel local service, such as at nighttime.

Commuter rail or suburban rail is a passenger rail 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.

The term can refer to systems with a wide variety of different features and service frequencies, but typically refers to mainline rail services connecting suburban communities with city centres over medium distances; it is distinguished from rapid transit systems which operate inside the urban core.

The Japan Railways Group, commonly known as the JR Group (Jeiāru Gurūpu) or simply JR, is a network of railway companies in Japan formed after the division and privatization of the government-owned Japanese National Railways (JNR) on April 1, 1987. The group comprises six regional passenger railway companies, one freight railway company, and two non-service entities. The JNR Settlement Corporation assumed much of the debt of the former JNR.

The companies of the JR Group operates a significant portion of Japan’s rail services, including intercity routes, commuter lines, and the Shinkansen high-speed rail network.

A train (from Old French trahiner, from Latin trahere, "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport.

Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive in the United Kingdom in 1802, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in the late 1800s to transport large numbers of people in and around cities. Beginning in the 1920s, and accelerating following World War II, diesel and electric locomotives replaced steam as the means of motive power. Following the development of cars, trucks, and extensive networks of highways which offered greater mobility, as well as faster airplanes, trains declined in importance and market share, and many rail lines were abandoned. The spread of buses led to the closure of many rapid transit and tram systems during this time as well.

Rail transportation in the United States includes freight and passenger service. Freight moves 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 136,729 miles (220,044 km). A larger fraction of freight moves by rail in the United States than in most countries and freight rail companies are generally profitable.

Passenger service includes mass transit in most major American cities. Except for commuter rail, most transit systems are not connected to the national rail network. Federal Railroad Administration regulations require passenger cars used on the national rail network to be heavy and strong enough to protect riders in case of collision with freight trains.
