The Mandarin Chinese word for “vehicle” is chē 車. There are many types of vehicles, so chē is combined with other words to describe everything from taxis to bicycles.

Trains were originally powered by steam and fire, so the Mandarin Chinese word for train is huǒchē 火車 – fire vehicle. The first character in huǒchē is 火 – fire.
