Now hit the capital and several millions of tube passengers experienced in warm summer weather underground thermal trip, transport for London has fixed it continues to try and cooling pipe
work in shanghai of the network.
Underground new air conditioning introduced s-stock tube train to continue on the line and Metropolitan line passengers this summer for the first time be able to use these routes to Central London.
In 2016, pipe network will use a new air conditioned trains, once the city spread out on the line, they will from 2012, circle and Hammersmith and City line and district line introduced from 2013.
But cooling challenges of deep-level tube lines is peak and continued to work in a day.
Tube is the world's oldest subway system and its basic tunnel infrastructure has changed very little since it's built more than 145 years ago.
Deep level line, which is unique to London, heat generated by the train had passed to the tunnel and for many years, meaning of clays around tunnel retains heat.
They also built the space and air-conditioned train only enough trains, inside or outside of a very small space.
Guan Hang TfL collection has created a common approach, including the Piccadilly and Bakerloo line trains designed to upgrade opportunities.
The London underground, using the train industry, train of development will be lighter and more energy efficiency, this would mean that the possibility of air conditioning equipment it can.
Use of regenerative braking, this time for the Rails return to power, close it at the same time will not increase the heat generated can, in turn, the power and air conditioning.
The current plan is a prototype will be delivered to the London underground, to the year 2015.
Dual fan capacity in all the service work of the main ventilation shaft of the Victoria line is due to complete later this year.
Total of 9 fan has been completed, work currently being carried out by the last four.
Throughout the Victoria line trains will be replaced later this week, this will make the operation regenerative braking system of environmental protection, it returned for rail power supply, while brake the train road.
This will reduce the generation of heat, therefore in tunnel temperature should be reduced.
Ventilation system with new trains, which will distribute cool air from the tunnel in the ground, and distribute it to the head height in transport, this will mean passengers more comfortable journey in the hot summer.
London transport Commissioner, Peter · Hengdigu says:
"Hot weather this week and we have seen over the network as we know it can, very uncomfortable, I wish to assure passengers we are working to overcome the unique cooling pipes of the great engineering challenges.
"We have made progress--air conditioning is now central London tube trains, network consists of a fleet of 57 air-conditioned train across London ground.
"Now joined on the all new double-decker bus fleet equipped with air cooling system and other open Windows now has also been installed at all double deck buses.
"Last summer on the Metropolitan line saw the first introduction of air conditioning tube trains, they now run during the summer for the first time in Central London.
"That by the year 2016, 191 air-conditioned trains will operate on the circle, district and Hammersmith and city and metropolitan lines.
"Victoria line the important work already improving ventilation, the customer's journey more comfortable.
"When customers should be found to have significant differences, we are able to use regenerative braking function of the new train, we will be able to do once the old trains is out of service".
