Rolling Stock

 

the quantity of railroad cars throughout the entire rail network of a given subdivision (department of railroads, of stations, and so forth). According to its purpose rolling stock is divided into passenger and freight, and according to its technical characteristics it is classified by the type of car (boxcar, gondola car, flatcar, and so forth), the number of axles per car (from two to eight and more), the clearance height and the gauge of the track (wide-gauge or narrow-gauge), freight capacity, and other factors. There is rolling stock for general and specialized use (for industrial transportation).

A distinction is made between inventory rolling stock, which includes all cars assigned to a given railroad, and available rolling stock, which consists of cars actually located within the bounds of a given railroad (no matter where they have been assigned). Available rolling stock is divided into operational stock used for commercial hauls and non-operational stock that is used for intrarailroad service runs and mobile workshops or is being repaired, and so forth. A special category of rolling stock is that which is kept in reserve; it is used during periods of mass hauls (export of grain and vegetables, transportation of farm equipment, and so forth).

Rolling Stock

 

all resources in the form of transport vehicles of all types that travel on track or on roads.

Rolling stock is broken down by sector, economic region, and country. It is classified according to function as passenger, freight, and special-purpose stock. Railroad rolling stock includes locomotives, self-propelled motorized cars (see), urban transit electric trains, diesel trains, railroad cars, and streetcars. The special-purpose rolling stock of railroads includes machines for track installation and maintenance, such as tracklayers, snowplows, and track liners. It also includes flatcar-mounted hoisting cranes, handcars, and other equipment. Railroad rolling stock is described in terms of load capacity, function, number of axles, type of traction (diesel or electric), and locomotive power.

Automotive rolling stock includes all classes of passenger cars, trucks, trailers and semitrailers, buses, and special-purpose firefighting, ambulance, and repair vehicles. It is described in terms of load capacity (for freight carriers), passenger capacity, number of axles, including drive axles, and type of engine (diesel or carburetor).

The concept of rolling stock is bound up with the qualitative characteristics of means of transport; quantitative characteristics are described by the concepts of motor vehicle pool, railroad-car fleet, and locomotive fleet.
