The London Underground. More than 40 degrees

Although Britain is not known as a particularly tropical country, in the summer months it is guaranteed to have at least one hot place: the London Underground. Hundreds of thousands of passengers sweat every day on the oldest underground train network in the world, in conditions reminiscent of a sauna.
But relief may soon be in store for these commuters, who wonder why the temperatures on the subway in their city are higher than those on the subway networks in Mexico City or Milan. Plans to install a cooling system that will use millions of gallons of cold groundwater may be skin and tendons before the summer of 2005.
Modern subway systems, such as those in Hong Kong and Singapore, have been designed so that the tunnels have enough space for air conditioning systems. However, in the 60's of the 19th century, not much thought was given to the problem of air conditioning and the subways in London only have room for the trains themselves. Last August, at the height of the hottest summer in years, when the temperature reached 40 degrees Celsius, the mayor, Ken Livingstone, offered a prize of 100 pounds for the most effective solution for cooling the rail network. The "Beat the Heat" competition attracted 3,400 contestants and included a proposal to place snowmen banners and a proposal to distribute snowmen; Most of the offers were rejected.
Graham Maidment, who helped prepare the winning scheme, said the system could lower the temperature by 7 degrees Celsius. The plan is to try a prototype of the system next year at Victoria station, the busiest in the city. In any case, it will take years before it is installed in the entire tunnel network.
