Rail tunnel that runs beneath the English Channel between Folkestone, England, and Sangatte (near Calais), France. A rail tunnel was chosen over proposals for a very long suspension bridge, a bridge-and-tunnel link, and a combined rail-and-road link. The 31-mi (50-km) tunnel, which opened in 1994, consists of three separate tunnels, two for rail traffic and a central tunnel for services and security. Trains, which carry motor vehicles as well as passengers, can travel through the tunnel at speeds as high as 100 mph (160 kph).
