Nearly five million people a day and more than half a billion a year waiting for trains at 468 stations and 27 move along the lines of the New York subway. Its purpose - to quickly get people from one end of town to another, without frills and ceremonies. Many complain that the stations here are the same, and generally dirty subway in New York unattractive. But if so, it is not everywhere, at any rate. Palaces of the stations to do here, though not tried, but some of them are very interesting and picturesque.

The first subway line was built in New York in 1904 and joined the City Hall (City Hall) with the intersection of 145th Street and Broadway - Avenue, which runs through the city.

Lisa Montanarella in the book "Curious Facts of New York" mentions that in the early 20th century, when there was no special equipment for the construction of tunnels and underground workers threatened not only the falls and lung disease, but also such a thing as a "blow" .

The fact that for underground construction of tunnels under the rivers during the work used compressed air, which did not allow water to seep into the ground in the worst. The tunnel was as if inflated from the inside, but if the hole was formed, compressed air pressure blew out and it would suck like a vacuum cleaner, even a person.

For example, in 1905, "blowing" experienced worker Dick Kridon. When he felt that he brings up from the tunnel, he absorbed the air, holding his breath, and felt then, as he had passed from the bottom up through the water fountain and threw into the air. He described his feelings in these words: "I was so squeezed, but squeezing has no girl." And it happened when laying a tunnel under the East River between Manhattan and Brooklyn.

Another detail of the history of the New York subway: before the 40-ies twisted passengers in cars when used bulbs in order to use them at home. Then come up with a special design of lamps unsuitable elsewhere. For example, they are not twisted in the clockwise and counterclockwise, and were fed a constant rather than alternating current.

The police keeps order in the central stations. Their walls are decorated with mosaics on the tile, and passing from line to line, you can feel yourself in the gallery of art. New York Metropolitan personnel are required to have plastic ID cards to enter their work-place. Check out thecardnetwork.co.uk for plastic ID cards for your business.
