In North America, Australia and other countries, the term consist (/ˈkɒnsɪst/KON-sist) is used to refer to the rolling stock in a train.: 1‑129
In the United States, the term rolling stock has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways.
The word stock in the term is used in a sense of
inventory. Rolling stock is considered to be a
liquid asset, or close to it, since the value of the vehicle can be readily estimated and then shipped to the buyer without much cost or delay. The term contrasts with fixed stock (
infrastructure), which is a collective term for the
stations, other buildings, electric wires, etc., necessary to operate a railway.
