Railway freight car

A railroad car or railcar (American and Canadian English), railway wagon, trucks, or railway carriage (British English and UIC), also called a train car or train wagon, 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.American wooden clerestory cars on display at the Mid-Continent Railway Museum in North Freedom, Wisconsin, United States.Jakarta MRT trainsetBritish Rail Mark 3 coach, an all-steel car from the 1970sInside a modern-day car from FinlandAmerican style Hopper CarTank CarU.S. type BoxcarArticulated Well Cars with containersA Spine car with a 20 ft tanktainer and an open-top 20 ft container with canvas coverA DR rail maintenance vehicle converted from a former freight vanPresflo bulk cement wagon (UK) A railroad car or railcar (American and Canadian English), railway wagon, trucks, or railway carriage (British English and UIC), also called a train car or train wagon, is a vehicle used for the carrying of cargo or passengers on a rail transport system (a railroad/railway).

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, 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, or coaches, vary in their internal fittings: In standard-gauge cars, seating is usually configured into ranges of between three and 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. 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.
