wooden shuttering were then placed immediately under the road surfaces. Construction of the roof

In the United States the first practical subway line was constructed in Boston between 1895 and
1897. On October 27, 1904, New York City opened the first section of what was to become the
largest subway system in the world. Other cities with notable subway systems include Philadelphia
and Chicago in the United States; Toronto and Montreal in Canada; Mexico City, Mexico; Buenos
Aires, Argentina; Munich and Frankfurt am Main in Germany; Milan, Italy; Cairo, Egypt; and
Tokyo, Kyoto, Osaka, and Nagoya in Japan. The shortest metro line was constructed in Turkey. Its
length is only 600 m but Istanbul is very proud of the metropolitan means of transport.
A number of major modern cities have a combination of subway and elevated railways. In
addition, some have automatic trains that are operated by remote control. Lines that use automated
trains include a section of the London subway system, the Victoria Line; BART (Bay Area Rapid
Transit) in the San Francisco Bay area; and the Washington, D.C., Metro. Greater attention is also
paid to the aesthetics, comfort, safety, and convenience of subways, particularly those in Moscow
and Rome.
