Train
A train is a set of railway cars (also called vehicles) that are tied together with or without a locomotive. Trains are used to carry people, and also things like raw material, finished goods, cargo, and waste. The vehicles that carry freight are called cars (in the United States) or wagons (in the United Kingdom). The ones that carry passengers are often called coaches or carriages. A place where a train stops to let people get on and off is called a train station or railway station.
