Channel Tunnel The Channel Tunnel (French: Le tunnel sous la Manche; also nicknamed Chunnel)[2][3] is a 50.45-kilometre (31.35 mi) rail tunnel linking Folkestone, Kent, in the United Kingdom, with Coquelles, Pas-de-Calais, near Calais in northern France, beneath the English Channel at the Strait of Dover. At its lowest point, it is 75 m (250 ft) deep below the sea bed, and 115 m (380 ft) below sea level.[4][5][6] At 37.9 kilometres (23.5 mi), the tunnel has the longest undersea portion of any tunnel in the world, although the Seikan Tunnel in Japan is both longer overall at 53.85 kilometres (33.46 mi) and deeper at 240 metres (790 ft) below sea level. The speed limit for trains in the tunnel is 160 kilometres per hour (99 mph).[7]
Channel 4 Channel 4 is a British public-service television broadcaster that began transmission on 2 November 1982. Although largely commercially self-funded, it is ultimately publicly owned; originally a subsidiary of the Independent Broadcasting Authority (IBA),[1] the station is now owned and operated by Channel Four Television Corporation, a public corporation of the Department for Culture, Media & Sport,[2] which was established in 1990 and came into operation in 1993. With the conversion of the Wenvoe transmitter group in Wales to digital on 31 March 2010, Channel 4 became a UK-wide TV channel for the first time.
