In the 1860s London was, quite literally, the capital of the world. 
The city was growing, and as its population grew as well, transport in the city became a big problem. Some new way of travelling 
was needed and people looked to the innovations of the Industrial 
Revolution. The invention of the steam engine was relatively new 
and exciting and people began to think that it could be possible to 
transport people by trains underground. So it was that in 1863, 
using techniques borrowed from digging tunnels for other uses, 
a 2-mile line from Paddington in West London to Farringdon in 
East London was built. Major cities all over the world soon copied 
this type of city transit engineering. The most famous include: 

1. Moscow underground which is the largest 
in terms of passenger numbers, with more 
than a billion passenger journeys a year. Some 
underground stations are very beautiful and 
include sculptures, mosaic pictures in the 
ceilings, picturesque decorations. The first line was open in the thirties of the 20”‘ century. It ran through 
the city centre and had just ten stations. 

2. The New York underground which is the 
largest in terms of kilometres covered. It is 
often called the “Subway” and is one of the 
world’s cheapest, with a single journey to and 
from any station just $2. It is characterized 
by the fact that its lines are named by num- 
bers and letters (like 1, 3 and A, D) and has 
carriages that are heated in winter and air- 
conditioned in summer. 

3. The Paris Metro which was built at the turn 
of the 20”‘ century and has 368 stations covering 15 lines and transporting around six 
million people daily. Some stations are designed in a Very artistic way characterized by flower and leaf motifs. The architect Hector 
Guimard decorated this mass transit system 
in tune with the city. 

4. The Tokyo subway which became notoriousz 
in 1995 when Aum Shinri Kyo cult used 
Sarin gas on a train, killing 12 people. However, it is one of the safest underground systemsand generally people characterize it as the 
world’s best in terms of ease of use and comfort. 

5 The London Underground (The Metropolitan Railway) which was opened in 1863 and Londoners at once began speaking about it as 
a fashionable way to travel. The Metropolitan 
Railway grew and began to be called the Tube 
because of the narrow tunnels that characterize the older parts of the system. Today the London Underground 
covers most of Greater London with 11 different lines and 970 
million passenger journeys every year.
