| London Underground
The London Underground is not only the oldest, it is also one
of the largest metro systems in the world. The first three stations
were built as early as 1863. After that, the system has gradually
expanded. By about 1910, the biggest part of the central area
and inner suburban network were completed. At this moment, the
London Underground covers 9 lines, 271 stations, 436.5 kilometres
of track, and more than 4,000 vehicles. The average ridership
is 2.5 million passengers a day.
Because of the piecemeal development of the metro system, the
Underground is highly diverse in terms of station layouts, means
of access, age and condition. The older parts were not designed
with crime prevention in mind and contain many inconvenient interchanges,
long passageways, and "blind corners". The variety of
design, age, and usage makes it harder to find crime prevention
measures which can be used on a general basis.
