In the early days of tube railways in London there was little short of a mad scamble to get new tubes authorised for construction. Private and institutional finance was tempted by the promise of moneymaking schemes. Few in the event made very much and some were just plain scams.
This book reveals over forty unfulfilled tubes that were presented to Parliament between 1880 and the start of the First World War, as well as many proposed variations to the tubes that were constructed.
