The Eurotunnel is a rail tunnel that runs beneath the English Channel, connecting England and France. It allows trains to travel between the two countries quickly and efficiently, making it easier for people and goods to move across borders. The tunnel is about 31 miles long, with a portion of it underwater, and it opened in 1994. Trains that use the Eurotunnel include the Eurostar, which carries passengers, and the Eurotunnel Le Shuttle, which transports vehicles. This impressive engineering feat has significantly reduced travel time between London and Paris, making it a popular choice for travelers and businesses alike.
