A 19th Century steam train took passengers on the London Underground today to mark the 150th anniversary of the first Tube journey in the capital.
Specially invited passengers moved off from Kensington Olympia Tube station in west London aboard a train pulled by Met Locomotive 1, which was built in 1898.
Passengers dressed in period costume enjoyed a trip on the restored 1898 Met Locomotive 1 today to mark the 150th anniversary of the London Underground.
The steam train headed to Moorgate underground station in the City of London after a journey from Olympia in west London.
London mayor Boris Johnson, who was among the passengers, described the journey as "romantic" and "pure Conan Doyle".
He said: "It was just extraordinary. We had steam coming in through the windows, huge thick clouds of white steam going past and then bits of soot coming through from the engine."
Johnson added: "It was fascinating, as the train started to go up from Kensington to Notting Hill you could feel the engine really strain, but as we levelled off it picked up a lot of speed. You could see how the Victorians were able to run a very timely service."
A 115-year-old restored steam train has begun its journey from its sheds near Earl's Court, London, as part of the celebrations for the 150th anniversary of the London Underground.
When Met Locomotive 1 reaches Kensington Olympia Tube station in west London, the Metropolitan Railway carriage No 353 will take a group of specially invited passengers to Moorgate station.

The passengers will be in the restored Metropolitan Railway carriage No 353, which was built in 1892, as well as a set of Chesham coaches on loan from the Bluebell Railway in Sussex.
Making up the train will be the No 12 Sarah Siddons - one of the world's oldest electric locomotives in service and was constructed in 1922.
The engine will travel non-stop to Moorgate station in the City of London and is due to reach its destination at 10:30am.
The historic train will travel slowly along the route, and can be seen at a number of Underground stations on-route, including Earl's Court, High Street Kensington, Bayswater, Paddington, Euston and King's Cross.
The Mayor of London Boris Johnson says that the London Underground is "still admired around the world" 150 years after the first trains set off on the Metropolitan Railway.
