The Channel Tunnel: Eurostar's Undersea Rail Link Between England and France

The Channel Tunnel (often called the Eurostar tunnel or "Chunnel") is a 50.5-kilometer (31.4-mile) undersea rail tunnel connecting Folkestone, Kent, England, with Coquelles, Pas-de-Calais, France. It runs beneath the Strait of Dover in the English Channel and is the world's longest undersea rail tunnel. High-speed Eurostar passenger trains and freight shuttles carry vehicles through its three tubes (two rail, one service). Opened in 1994, it has become a vital transport artery between the UK and continental Europe.
