THE CHANNEL TUNNEL
The first design of the Channel Tunnel was proposed in 1751. Since
that time, dozens of proposals had been considered before the actual
tunneling began. The work proceeded very quickly and was successfully
completed in 6 years. The Tunnel was opened for traffic on May 7, 1994.
The Channel Tunnel actually consists of three tunnels: the two
running tunnels* and the service tunnel**. Single-track railway lines are
laid down in each of the running tunnels. Normally, one of them carries
passenger and freight trains from Britain to France and the other carries
trains in the opposite direction. If one of the running tunnels is closed
down for maintenance, the other is used for train movement in both
directions. A smaller third tunnel lies between the two train tunnels. It is
called the service tunnel. There is a roadway inside it, so maintenance
workers and emergency teams can reach any point of the Tunnel system
in their road vehicles. The service tunnel is linked to the running tunnels
at regular intervals by cross-passages***. In case of emergency or a train
breakdown, the passengers will leave the train through one of the cross-
passages into the service tunnel where road vehicles will evacuate them
to a safer place.
The total length of the Tunnel is about fifty kilometers. Thirty-seven
kilometers of the line are under the waters of the English Channel. The
electric trains run every three minutes during peak hours, providing the
carrying capacity of 4,000 vehicles per hour in both directions.
A typical passenger shuttle consists of twenty-six wagons. A half of
them are double-deck carriages for carrying cars of average size. Thirteen
single-deck wagons are used for transporting buses and vans. Freight
shuttles consist of twenty-five single-deck wagons. Each of them is capable
of carrying a vehicle weighing up to forty-four tons. Two electric
locomotives are coupled in front and at the rear of each shuttle.
The time of crossing the Tunnel is thirty-five minutes, about an hour
less than by ferry. Passengers and drivers remain in their vehicles. The
gauge of the tunnel railway is standard that is why the tunnel can be
used for international passenger and freight trains.
Notes: *running tunnel – железнодорожный тоннель
**service tunnel – служебный тоннель
***cross-passage – поперечный переход
