Transportation, to go around London (Click here)



Either you can use the taxi or the bus.You can go around London and also you can use the
 train underground or tube they call it.:)

Double Decker Bus
A double-decker bus is a bus that has two storeys or 'decks'. While double-decker
 long-distance coaches are in widespread use around the world, double-decker city
 buses are less common. Double-decker buses are popular in some cities of Europe
 and in parts of Asia, usually in former British colonies (Hong Kong, Singapore etc.)
Some double-deckers specialise in short sight-seeing tours for tourists for,
 as William Ewart Gladstone observed, "the way to see London is from
the top of a 'bus". (Gladstone was referring to London's once ubiquitous double-deck
 horse drawn omnibuses, rather than a motor bus).^[1]

Taxi London

A hackney or hackney carriage (also called a cab, hack or London taxi) is a
carriage or automobile for hire. A livery carriage superior to the hackney was
 called a remise.In the United Kingdom, the name hackney carriage
 refers to a taxicab licensed by the Public Carriage Office in Greater London
or by the local authority (non-metropolitan district councils or unitary authorities)
 in other parts of Great Britain, or by the Department of the Environment in
Northern Ireland.In the United States, the police department of the city of Boston
 has a Hackney Carriage Unit, analogous to taxicab regulators in other cities,
that issues Hackney Carriage medallions to its taxi operators.
