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

method. The trial, which begins this summer, aims to make it cooler for passengers on platforms and will be tested at Victoria station which is so deep that it is successfully beneath water and pumps out 35 litres (eight gallons) a second, to quit it coming via the walls. The concept of the new system is to push the water by way of 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 employed to power properties 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 getting put into work as properly 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 might influence the London Tube in a drastic way. Some of the Tube lines could be closed especially on the hot summer time days. London Underground assures that there are no plans to close any Tube Lines during the summer but in the future years it may well get to the point "where the underground will become literally intolerable and you could face the prospect of loss of life" as Mr Livingstone from LU suggested.

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