Перевести текст на язык. london's underground it was the year 1863 and on one historic day 30,000 londoners used a new and strange mode of travel — the first underground railway in the world. the first train covered the distance of almost four miles. some engineers had said before the railway was completed, that the tunnels would fall in because of the weight of the traffic in the streets above; the houses would be shaken to the ground by the vibration of the trains and londoners would be poisoned by the fumes from the engine. but the fantastic railway was completed and opened. at first the carriages were "blind" and the trains were cable operated. 1 then came "twopenny tube"2 which had small electric trains. the price of tickets was two pennies for any distance. now there are different trains going in many different directions. there is the old tube across the centre with many and frequent stops and there are trains going out to the suburbs and stopping at a very few stations on the way. and there are the non-express trains going a very long way out into the country. the fares are all different and even the carriages are not alike. safety has always been one of the main concerns of london transport. in spite of the fact that trains often follow each other within seconds it has been claimed that the london tube is the safest form of transport. automatic signalling worked by electric circuit is operated by the trains themselves. a programme machine controls routes: any changes are made automatically with great speed.
