用於運載大量旅客往返城郊間的地下鐵路系統，列車通常包含數個車廂，並以多機運作系統加以操控。為了方便施工，地下鐵一般建置於城市街道底下，但有時也會穿越河川下層。駛入郊區後，通常會將系統建置於地面上，並與原有的鐵路系統或加高的運輸路線結合。

英文....

Underground railway systems used to transport large numbers of people within urban and suburban areas typically by means of trains comprised of a number of cars operated on the multiple-unit system. Subways are usually built under city streets for ease of construction, but they sometimes must pass under rivers. Outlying sections of the system usually emerge aboveground, blending into conventional railways or elevated transit lines.
