13 January 2013 Last updated at 18:44 GMT

A steam train which carried passengers in the 19th Century has returned to the Tube to mark 150 years since the first London Underground journey.

Ticket holders travelled along part of the original Metropolitan Line - now the Hammersmith & City Line.

They travelled in coaches pulled by an 1898-built steam engine, known as Met Locomotive No 1.

BBC London's Nick Beake spoke to London Mayor Boris Johnson and steam enthusiasts.
