1. Bands were playing and the gentlemen in hats were preparing to make speeches about their great achievement. They made the first underground railway travel in the world — a distance of almost four miles.
It was the year 1863 and on that first historic day 30,000 Londoners used this new and strange way of travel. Now more than a hundred years later the London Underground carries more than a million passengers every day. The total number of passengers carried by the London Underground each year is enormous, and it is constantly growing.
2. In the early days the trains were driven by steam locomotives which burnt coal.
It is said that the train staff and porters' asked permission to grow beards and moustaches — as an early form of smog mask.
Now the atmosphere "underground" is considered even better than that outside as germs cannot grow in the dry air, and the trains, of course, are electric.
