A railroad car, railcar (American and Canadian English),^[a] railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system (a railroad/railway). Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.

The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner,^[1] though the term has other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries "railcar" refers specifically to a self-propelled, powered, railway vehicle.

Although some cars exist for the railroad's own use – for track maintenance purposes, for example – most carry a revenue-earning load of passengers or freight, and may be classified accordingly as passenger cars or coaches on the one hand or freight cars (or wagons) on the other.

Passenger cars[]

Passenger cars, or coaches, vary in their internal fittings:

In standard-gauge cars, seating is usually configured into ranges from three to five seats across the width of the car, with an aisle in between (resulting in arrangements of 2+1, 2+2 or 3+2 seats) or at the side. Tables may be provided between seats facing one another. Alternatively, seats facing in the same direction may have access to a fold-down ledge on the back of the seat in front.

• If the aisle is located between seats, seat rows may face the same direction, or be grouped, with twin rows facing each other.
• In some vehicles intended for commuter services, seats are positioned with their backs to the side walls, either on one side or more commonly on both, facing each other across the aisle. This gives a wide accessway and allows room for standing passengers at peak times, as well as improving loading and unloading speeds.
• If the aisle is at the side, the car is usually divided into small compartments. These usually contain six seats, although sometimes in second class they contain eight, and sometimes in first class they contain four.

Passenger cars can take the electricity supply for heating and lighting equipment from either of two main sources: directly from a head end power generator on the locomotive via bus cables, or by an axle-powered generator which continuously charges batteries whenever the train is in motion.

Modern cars usually have either air-conditioning or windows that can be opened (sometimes, for safety, not so far that one can hang out), or sometimes both. Various types of onboard train toilet facilities may also be provided.

Other types of passenger car exist, especially for long journeys, such as the dining car, parlor car, disco car, and in rare cases theater and movie theater car. In some cases another type of car is temporarily converted to one of these for an event.

Observation cars were built for the rear of many famous trains to allow the passengers to view the scenery. These proved popular, leading to the development of dome cars multiple units of which could be placed mid-train, and featured a glass-enclosed upper level extending above the normal roof to provide passengers with a better view.

Sleeping cars outfitted with (generally) small bedrooms allow passengers to sleep through their night-time trips, while couchette cars provide more basic sleeping accommodation. Long-distance trains often require baggage cars for the passengers' luggage. In European practice it used to be common for day coaches to be formed of compartments seating 6 or 8 passengers, with access from a side corridor. In the UK, Corridor coaches fell into disfavor in the 1960s and 1970s partially because open coaches are considered more secure by women traveling alone.^{[citation needed]}

Another distinction is between single- and double deck train cars. An example of a double decker is the Amtrak superliner.

A "trainset" (or "set") is a semi-permanently arranged formation of cars, rather than one created "ad hoc" out of whatever cars are available. These are only broken up and reshuffled 'on shed' (in the maintenance depot). Trains are then built of one or more of these 'sets' coupled together as needed for the capacity of that train.

Often, but not always, passenger cars in a train are linked together with enclosed, flexible gangway connections through which passengers and crewmen can walk. Some designs incorporate semi-permanent connections between cars and may have a full-width connection, effectively making them one long, articulated 'car'. In North America, passenger cars also employ tightlock couplings to keep a train together in the event of a derailment or other accident.

Many multiple unit trains consist of cars which are semi-permanently coupled into sets: these sets may be joined together to form larger trains, but generally passengers can only move around between cars within a set. This "closed" arrangement keeps parties of travellers and their luggage together, and hence allows the separate sets to be easily split to go separate ways. Some multiple-unit trainsets are designed so that corridor connections can be easily opened between coupled sets; this generally requires driving cabs either set to the side or (as in the Dutch Koploper or the Japanese 285 series) above the passenger compartment. These cabs or driving trailers are also useful for quickly reversing the train.

Freight cars[]

Freight cars (US/Canada), goods wagons (UIC), or trucks (UK) exist in a wide variety of types, adapted to carry a host of goods. Originally there were very few types of cars; the flat car or wagon, and the boxcar (US/Canada), covered wagon (UIC) or van (UK), were among the first.

Types of freight cars[]

Freight cars or goods wagons are generally categorized as follows:

• Boxcar (US and Canada), covered wagon (UIC) or van (UK): fully enclosed car with side or end doors. Standard boxcars have about 3.5 times the capacity of a standard Semi-trailer.^[2]
  • Covered wagon (UIC), van (UK) or boxcar (US/Canada): fully enclosed wagon for moisture-susceptible goods.
  • Hicube boxcars: high-capacity high-clearance boxcar
  • Refrigerator car or reefer (US/Canada): refrigerated boxcar for fruits and vegetables.
• CargoBeamer
• Coil car: specialized flat or gondola for heavy sheet metal rolls
• Combine car: combined passenger car and boxcar in one wagon
• Flatcar (or flat): for larger bulky loads. Specialized flat cars include:
  • Aircraft Parts Car: with fixtures for large aircraft parts.
  • Autorack (also called auto carriers): multi-level flat for automobiles.
  • Centerbeam cars (US): specialized flat for building materials.
  • Conflat (UK): specialized flat for containers.
  • CargoSprinter: self-propelled container flat.
  • Container flatcar
  • Depressed-center flatcar or Wellcar or Lowmac (UK): for high-clearance loads (e.g. transformers and boilers)
  • Semi-trailer flatcar
  • Rolling highway: a train designed to carry trucks and/or semi-trailers
  • Single container car; Spine car, a center sill and side sill only car with lateral arms to support intermodal containers. See also Well car.
  • Double container car; Well car or double-stack car. Cars for transporting Intermodal containers with a low deck to allow double stacking, commonly used in articulated form. See also Spine car
• Schnabel car: for unusually large and heavy industrial equipment (transformers, boilers, reactors, distillation columns,...)
• Gondola (US): car with open top, enclosed sides and ends for bulk goods.
  • Covered hopper: specialized hopper car with a cover for weather sensitive loads (grain, pellets,...)
  • Open wagon (UIC): railway wagon with an open top but enclosed sides and ends, for bulk commodities and other goods that might slide off.
  • Hoppers: similar to gondolas but with bottom dump doors for easy unloading of things like coal, ore, grain, cement, ballast and the like. Short hoppers for carrying iron ore are called ore jennys in the US.
  • Lorry (US/Canada): An open wagon (UIC) or gondola (US/Canada) with a tipping trough, often found in mines. See also Tippler.
  • Mine car
  • Mine cart (e.g., V skip wagon).
  • Side dump cars: used to transport roadbed materials such as, ballast, riprap, and large stone, and are able to unload anywhere along the track.
  • Tippler (UK): An open wagon with no doors or roof which are unloaded by being inverted on a Wagon Tippler (UK) or Rotary car dumper (US/Canada). They are, used for minerals, such as coal, limestone and iron ore as well as other bulk cargo. See also Lorry.

Aluminium cars[]

The first two main-line all aluminum passenger cars were exhibited at the 1933-35 Chicago World's Fair by Pullman Company.^[5] Aluminum freightcars have a higher net-to-tare ratio of 4.9 than traditional steel based wagons, which have 3.65.^[6]

Military armoured trains use several types of specialized cars:

Mobile missile systems[]

During the Cold War, the Soviet Union fielded a number of trains that served as mobile missile silos. These trains carried the missile and everything necessary to launch, and were kept moving around the railway network to make them difficult to find and destroy in a first-strike attack. A similar rail-borne system was proposed in the United States of America for the LGM-30 Minuteman in the 1960s, and the Peacekeeper Rail Garrison in the 1980s, but neither were deployed.^[9] The Strategic Air Command's 1st Combat Evaluation RBS "Express" did deploy from Barksdale Air Force Base with radar bomb scoring units mounted on military railroad cars with supporting equipment, to score simulated thermonuclear bombing of cities in the continental United States.^[10]
