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.

James Whitaker Wright was a company promoter and swindler, who committed suicide at the Royal Courts of Justice in London immediately following his conviction for fraud.
