Navvies are shown mixing concrete under the supervision of their foreman, during the building of London's Metropolitan Railway. The line's engineer, John Fowler (1817-1898) commisioned this series of photographs recording the construction of the line, which was the world's first underground railway. On January 10 1863, the Metropolitan Railway operated its first service, which ran from Farringdon Street north to King's Cros, and west to Paddington (Bishop's Road), utilising trains hauled by steam engines.
