Legal history
Originally the railway was promoted by the Bristol Port Railway and Pier Company, incorporated under the Bristol Port, Railway and Pier Act 1862 of 17 June 1862. In 1871 the railway was transferred to the Great Western and Midland railway companies jointly, under the Great Western and Midland Railway Companies (Clifton and Bristol) Act 1871 (34 & 35 Vict. c. xi) of 25 May 1871, and the Midland Railway (Additional Powers) Act 1890 of 25 July 1890. The line was administered by the Clifton Extension Railway Joint Committee until 1894, and from then the Great Western and Midland Railways Joint Committee.
