Plate from the Illustrated London News (Vol 67/1 p 632). 'Section of the Thames Embankment, showing (1) The Subway, (2) The Low level sewer, (3) The Metropolitan Railway, and (4) The Pheumatic Railway' intended to link Charing Cros and Waterloo. This is one of several plans for the Thames Embankment, drawn up by Sir Joseph Bazalgette (1819-91). The tunnels were intended to improve the drainage of London as well as to provide services such as water, mains, gas pipes and telegraph cables. The pheumatic or atmospheric railway, based on George Medway's 1810 idea, was revived in 1860 by the Pheumatic Despatch Company and demonstrated at the Crystal Palace exhibition of 1864.
