The first underground system was proposed by Charles Pearson in 1843. Twenty years later the first line of the London Underground was opened for traffic. In the early days, the trains were driven by steam locomotives, which burnt coal, filling the tunnels with smoke. It is said that the train staff and porters asked for a permission to grow beards and moustaches – as an early form of smog mask. The tunnels of the first underground were made as small as possible in order to reduce the construction costs. According to Pearson’s project, all lines were laid down close to the ground surface. The first escalator was also installed in theLondon Underground in 1911. The railways were prepared for any emergency that might occur. To minimize the danger of flooding the underground near the Thames, isolating doors were built in the tunnels. All the trains were equipped with special reduced lighting for using on open sections of track.
Hello, my name is Nikita. My favorite magazine National Geography. It is very informative and interesting. I learn a lot of new! I like traveling very much, and this magazine about travel and different countries. Most of all I like Thailand. In the last issue of the magazine, I learned a lot about this country. For example, the fact that the inhabitants of the state, very friendly, value their history and traditions. This is a very ancient country, a variety of temples, architecture, exotic pets. Here with love meet tourists and organize different excursions. I especially like the symbol of their country - the golden dragon.. Still I would like to go to the Philippines and the Crimea, looking forward to the release of the next issue.
