The Baker Street and Waterloo Railway (BS&WR), also known as the Bakerloo tube, was a railway company established in 1893 that built a deep-level underground "tube" railway in London. The company struggled to fund the work, and construction did not begin until 1898. In 1900, work was hit by the financial collapse of its parent company, the London & Globe Finance Corporation, through the fraud of Whitaker Wright, its main shareholder. In 1902, the BS&WR became a subsidiary of the Underground Electric Railways Company of London (UERL) controlled by American financier Charles Yerkes. The UERL quickly raised the funds, mainly from foreign investors.
There were a number of proposals to build an underground railway along the Edgware Road in north-west London, England, at the end of the 19th century. Each scheme envisaged building some form of rail tunnel under Edgware Road towards Victoria railway station.
