A newly restored steam engine built in 1898, known as Met Locomotive No. 1, travels through Baker Street Underground station on December 16, 2012 in London, England. The train took part in a practice run for a commemorative journey to celebrate the 150th anniversary of the inaugural public passenger journey on the London Underground, the world's first underground railway, on January 9, 1863. Met Locomotive No. 1 will retrace the original London Underground journey on a stretch of the Metropolitan Railway on Sunday, January 13, 2013.
