Rolling stock

Rolling stock is the communal term that describes all the vehicles which move on a railway. It usually includes both powered and uncovered vehicles, for example locomotives, railroad cars, coaches and wagons. The term is sometimes used to refer only to non-powered vehicles, specifically excluding locomotives.The term contrasts with fixed stock, which is a communal term for the track, signals, stations and buildings etc. necessary to operate a railway. However this latter term is now much less widely used than rolling stock. Fixed stock is also called infrastructure.
