Apassenger train is atrain used to transport people along a railroad line, as opposed to afreight train that carriesgoods.[1][2] These trains may consist of unpoweredpassenger railroad cars (also known as coaches or carriages)hauled by one or morelocomotives, or may be self-propelled; self propelled passenger trains are known asmultiple units orrailcars. Passenger trains stop atstations or depots, where passengers may board and disembark. In most cases, passenger trains operate on a fixedschedule and have priority over freight trains.
Car design and the general safety of passenger trains have dramatically evolved over time, making travel by rail remarkably safe. Some passenger trains, both long-distance and short-distance, usebi-level (double-decker) cars to carry more passengers per train. Sleeper trains includesleeping cars with beds. Passenger trains hauled by locomotives are more expensive to operate than multiple units, but have a higher passenger capacity.[3]
Manyprestigious passenger train services have been bestowed aspecial name, some of which have become famous in literature and fiction.[citation needed]
The first occasion on which a railway locomotive pulled a train carrying passengers was in theUnited Kingdom in 1804, atPenydarren Ironworks inWales, when 70 employees of the ironworks were transported 9 miles by an engine designed byRichard Trevithick.[4][5] The first passenger train in regular service was a horse drawn train on theSwansea and Mumbles Railway which opened in 1807.[6] In 1808, Trevithick ran a passenger-carrying exhibition train calledCatch Me Who Can on a small loop of track in London.[4] The exhibition, which ran for two weeks, charged passengers for rides.[4]
The first steam train carrying passengers on a public railway was hauled byLocomotion No. 1 on theStockton and Darlington Railway in1825, traveling at speeds up to 15 miles per hour.[7]
Travel by passenger trains in theUnited States began in the 1830s and became popular in the 1850s and '60s.[8][9]
The first electric passenger train was exhibited at theBerlin Industrial Exposition 1879.[10] The first successful commercial electric passenger train, theGross-Lichterfelde Tramway, ran a year later inLichterfelde.[10]

Long-distance trains travel between many cities or regions of a country, and sometimes cross several countries. They often have adining car or restaurant car to allow passengers to have a meal during the course of their journey. Trains travelling overnight may also havesleeping cars. Currently, much of travel on these distances of over 500 miles (800 km) is done by air in many countries but in others long-distance travel by rail is a popular or the only cheap way to travel long distances.
One notable and growing long-distance train category is high-speed rail, which generally runs at speeds above 200 km/h (120 mph) and often operates on a dedicated track that is surveyed and prepared to accommodate high speeds.[12] The first successful example of a high-speed passenger rail system was Japan'sShinkansen, colloquially known as the "bullet train", which commenced operation in October 1964.[13] Other examples includeItaly'sLe Frecce,France'sTGV (Train à Grande Vitesse,lit. 'high speed train'),Germany'sICE (Inter-City Express), andSpain'sAVE (Alta Velocidad Española) inEurope.
In most cases, high-speed rail travel is time- and cost-competitive with air travel when distances do not exceed 500 to 600 km (310 to 370 mi), as airportcheck-in and boarding procedures can add at least two hours to the overall transit time.[14] Also, rail operating costs over these distances may be lower when the amount ofjet fuel consumed by anairliner duringtakeoff andclimbout is taken into consideration. Air travel becomes more cost-competitive as the travel distance increases because the fuel accounts for less of the overall operating cost of the airliner.
Some high-speed rail systems employtilting technology to improve stability in curves. Examples of tilting trains are theAdvanced Passenger Train (APT), thePendolino, theN700 Series Shinkansen,Amtrak'sAcela and the SpanishTalgo. Tilting is a dynamic form ofsuperelevation, allowing both low- and high-speed traffic to use the same trackage (though not simultaneously), as well as producing a more comfortable ride for passengers.
"Inter-city" is a general term for any rail service that uses trains with limited stops to provide fast long-distance travel. Inter-city services can be divided into three major groups:
The distinction between the three types of inter-city rail service may be unclear; trains can run as InterCity services between major cities, then revert to an express (or even regional) train service to reach communities at the furthest points of the journey. This practice allows less populous communities to be served in the most cost-effective way, at the expense of a longer journey time for those wishing to travel to theterminus station.
Higher-speed rail services operate at top speeds that are higher than conventional inter-city trains but below high-speed rail services. These services are provided after improvements to the conventional rail infrastructure to support trains that can operate safely at higher speeds.
Many cities and their surrounding areas are served bycommuter trains (also known as suburban trains, orS-Bahn in theGerman-speaking world), which servecommuters who live outside of the city they work in, or vice versa. More specifically, in theUnited States commuter rail service is defined as, "short-haul rail passenger transportation in metropolitan and suburban areas usually having reduced fare, multiple ride, and commuter tickets and morning and evening peak period operations".[16] Trains are very efficient for transporting large numbers of people at once, compared to road transport. While automobiles may be delayed bytraffic congestion, trains operate on dedicated rights-of-way which allow them to bypass such congestion.[17]
With the use ofbilevel cars, which are tall enough to have two levels of seating, commuter rail services can haul as many as 150 commuters per train car, and over 1,000 per train: much more than the capacity of automobiles and buses.[18][19]
InBritish andAustralian usage, a "railcar" is a self-propelledrailwayvehicle designed to transport passengers. The term is usually used in reference to a train consisting of a singlepassenger car (carriage, coach) with a driver'scab at one or both ends. Some railways, e.g. theGreat Western Railway, used the term "railmotor". If the railcar is able to pull a full train, it is more likely to be called a "motor coach" or a "motor car".[20] The term "railcar" is sometimes also used as an alternative name for the small types ofmultiple unit that consist of more than one coach.
Rapid transit trains are trains that operate in urban areas on exclusiverights-of-way in that pedestrians and road vehicles may not access them.[21] InEurope, rapid transit is widely known as ametro.
Light rails are electrically powered urban passenger trains that run along an exclusive rights-of-way at ground level, raised structures, tunnels, or in streets. Light rail systems generally use lighter equipment that operate at slower speeds to allow for more flexibility in integrating systems into urban environments.[22]
Trams (also known as streetcars in North America) are a type of passenger train that runs atramway track on or alongside public urban streets, often including segments ofright-of-way for passengers and vehicles.[23][24]
Heritage trains are often operated by volunteers, oftenrailfans, as a tourist attraction or as a museum railway.[25] Usually, the trains are formed from historic vehicles retired from national commercial operation that have retained or assumed the character, appearance, and operating practices of railways in their time. Sometimes lines that operate in isolation also provide transport facilities for local people. Much of the equipment used on these trains' systems is original or at least aims to replicate both the look and the operating practices of historic/former railways companies.[26]
Passenger rail is one of the modes of travel with the lowest carbon dioxide emissions. Rail travel emits much less carbon dioxide per mile thanair travel (2–27%) orcar travel (2–24%).[27]
