London's lost underground lines - with a note on the wine cellar of the National Liberal Club

Jago Hazzard is our guide to a collection of lost lines, repurposed lines and abandoned oddments, some of them 50 miles out of London and deep in the Buckinghamshire countryside.

One scheme that never advanced far enough to carry trains was the Waterloo & Whitehall Railway, which:

was authorised in 1865 to construct a pneumatic railway (that is, one where trains are pushed though a tunnel by air pressure) from Great Scotland Yard to Waterloo station. The single cast iron tube, 3.89 m (12'9") in diameter, would have crossed the river by being laid in a ditch dredged in the bed of the Thames. 

Though work did start, a general financial crisis prevented additional capital being raised, and the work was abandoned in 1868, with the company being wound up in 1882. The trench excavated at the northern end is now the wine cellar of the National Liberal Club.
