After the completion in 1868 of the Aylesbury and Buckingham Railway, the Duke of Buckingham built the light railway to provide freight access by rail to his estates at Wotton Underwood. The extension to Brill gave access to a brickworks there. The line was opened in 1871, and following public demand passenger facilities were provided early in 1872. Originally known as the Brill Tramway, the line's name changed to "Oxford and Aylesbury Tramroad" when a company was formed in an abortive attempt to extend the line to Oxford; the biggest hindering expense was the cost of tunnelling under Brill Hill.
