Train.
1. (Machinery.) A set of wheels, or wheels and pinions in series, through which motion is transmitted in regular consecution: e. g. the train of a watch; the wheels intervening between the barrel and the escapement. Striking-clocks have two trains; the going train, by which the hands are turned, and the striking train, by which the striking part is actuated. Watches and clocks which do not strike are destitute of the latter.

4. (Metallurgy.) Two or more pairs of connected rolls in a rolling-mill and worked as one system. The first pair are known as the muck, or puddlebar train and the finishing as the merchant-train.
5. (Railway.) A series of cars coupled together.
6. (Vehicle.) A heavy long sled used in Canada in hauling wood or merchandise.
