The soaring temperatures on the London Tube more than the summer time months have been a problem for some years now. A London Underground group has attempted to come up with some engineering solutions to the difficulty by making a groundwater cooling

technique. The trial, which starts this summer season, aims to make it cooler for passengers on platforms and will be tested at Victoria station which is so deep that it is effectively below water and  pumps out 35 litres (eight gallons) a second, to stop it coming via the walls. The thought of the new technique is to push the water through a network of pipes into heat exchange units on the platforms, which will suck in warm air and pump out cooler air. The heat could be utilised to energy houses and offices above and this way the temperature will be brought down.

But this is only a trial to be tested this year and it is far from being place into function as effectively as new trains with air cooling systems that are promised for Circle, District, Hammersmith and City and Metropolitan lines.

Meanwhile the temperatures in the deepest tunnels, reach 30C (86F) in summer season.

These alterations may affect the London Tube in a drastic way. Some of the Tube lines may be closed particularly on the hot summer season days. London Underground assures that there are no plans to close any Tube Lines in the course of the summer time but in the future years it might get to the point "where the underground will turn out to be literally intolerable and you could face the prospect of loss of life" as Mr Livingstone from LU advised.

About 1,000 London Tube passengers had been trapped for nearly two hours when 3 trains had been held up in a tunnel. The Central Line closed right after signal failures stopped the trains amongst Marble Arch and Lancaster Gate. The trains have been evacuated and three people had been treated for the effects of heat. return to site seo services privacy
