Tube network is 'best' in Europe

London's Tube network which carries more than one billion people a
year has been judged best in Europe by the transit industry's Metro
Awards.

The world's oldest metro system, which began service in 1863 and
covers 249 miles (402km), was also commended for passenger
satisfaction.

The Tube service beat off competition from Paris, Madrid, Berlin and
Copenhagen.
[...]
The Tube was judged on several criteria including customer service
levels, geographical coverage, technological innovations, safety and
security and the condition of the network.
