Channel Crossing to France

0400 up and driving to the" Chunnel", reservations for 0500. The train carrying the passanger cars/people travells @ 143 kmh, and it takes 35 minutes to get to France under the English Channel.
There are a number of Trains coming and going, with two tunnels and one service tunnel.

The Channel Tunnel is a world-famous underground tunnel stretching from the coast of England to the coast France, spanning the depths of the English Channel. For many travellers, the Channel Tunnel is an incredible feat of engineering, a marvel to be revered and respected. For others, it’s just an excellent way of getting from the British Isles to the Continent. It has proven to be a magnificent success since its opening, transporting millions of travellers swiftly and comfortably each year, and is a form of travel growing in popularity year by year.

How the Channel Tunnel Works

The three tunnels (made up of two single-track railway tunnels and a much smaller service tunnel that is used as an emergency exit) that were excavated through the chalky ground are coated with pre-cast concrete panels. However, the English sides and French sides differ slightly; the French used cast iron or high-strength concrete, but the English only used iron-lined parts in areas of bad geology. The rail tunnels are 25 foot in diameter, and 30 metres apart.
The Channel Tunnel carries different types of trains; some are shuttle trains that passengers can drive on and off with their cars, others are operated by Eurostar. However, all of the lines are electric.

Some Channel Tunnel Facts & Figures

  • The French call the tunnel Le Tunnel sous la Manche.
  • Ten workers were killed during the construction of the tunnel, most of them during the first few years of tunnelling.
  • It is considered to be on of the seven wonders of the modern world.
  • The Channel Tunnel is the longest undersea tunnel in the world, measuring in at 23.5 miles (Japan has longest overall tunnel).
  • The overall length of the tunnel is 31.4 miles.
  • The deepest point of the tunnel is 250 metres below the surface of the water.
  • The tunnel itself now carries Eurostar trains, and Eurotunnel car and freight trains, which take cars from A to B.
  • After all of the problems and hold ups, the project was 80% over budget.
  • It is known colloquially as the ‘Chunnel’.
  • It was thought that the tunnel would surpass the need for Ferry crossings, but the Dover to Calais Journey still remains popular.
  • The Channel Tunnel cost enough money to make the Golden Gate Bridge in America 700 times over.
  • On the English side, over 4 million cubic litres of chalk were exhumed.
  • The machines used to bore through the chalk rock were discarded after completion of the project by turning away from the tunnel at a right angle and tunnelling away.
