railroad car, railcar American and Canadian English,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,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 ââ¬â for track maintenance purposes, for example ââ¬â 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.
