London's District Railway: a history of the Metropolitan District Railway Company. Volume 1: Nineteenth Century

摘要

The high cost of constructing a railway through the centre of the City is captured on page 149 where it is stated: 'west of the King William statue it [the cost of land] had been as high as £30 per inch'. Although there was a strong sense that there was a need for a circular railway around the cities of London and Westminster this took a long time to achieve although the Metropolitan Railway had partially opened an underground railway in January 1863 from what is now Paddington to King's Cross and extended it two years later into the City of London to what would become Liverpool Street station. At Farringdon Street it connected with a railway which tunnelled under the Thames.
