What is the chunnel in Europe?

The Channel Tunnel (also called the Chunnel) is a 50.5-kilometre (31.4-mile) undersea rail tunnel that connects Folkestone, Kent, in the United Kingdom, with Sangatte, Pas-de-Calais, near Calais, in northern France, beneath the English Channel at the Strait of Dover. It is, at present, the longest undersea rail tunnel in the world.

- The Channel Tunnel was built from 1988 to 1994 and was officially opened on 6 May 1994. It is operated by Eurotunnel.

- Passenger shuttle trains carry vehicles (cars, coaches, and lorries) and their passengers; high-speed passenger trains, such as the Eurostar, use specially designed Eurotunnel Class 374 locomotives.

- The tunnel consists of three parallel tunnels: two rail tunnels, each carrying a single track railway line; and a service tunnel, which contains various equipment and is used for maintenance. The cross-section of each rail tunnel is roughly circular and has a diameter of 7.6 metres (25 ft).

- The trains travelling through the Channel Tunnel reach speeds of up to 160 kilometres per hour (99 mph).

- The Channel Tunnel is a major transport link between the United Kingdom and continental Europe, and it has significantly reduced travel times between the UK and France. It is estimated that approximately 10,000 people travel through the Channel Tunnel each day.
