the intent to build a single-track standard gauge railway the from Avonmouth to the city centre alongside the Avon. The railway's act of parliament was passed on 17 July 1862, and the railway opened on 6 March 1865, running from a terminus called Clifton in the Avon Gorge. As built, the railway was isolated from the rest of the national network, having not been intended for anything more than local traffic, so a connection to the main line railways was needed in order to develop Avonmouth as a port. However, due to the position of Clifton station and the large amount of developed land in the Hotwells area, an extension towards Bristol Temple Meads, the city's main station, would have been prohibitively expensive. Instead, a link was proposed from the BPRP at Sneyd Park, running under Clifton Down and through the suburbs to connect to the main lines of the Midland and Bristol and South Wales Union railways. The connection was authorised in 1867, but the BPRP was in financial difficulties, and so unable to complete the line. It entered into negotiations with the Midland and Great Western Railways (the latter now the owner of the Bristol and South Wales Union Railway). Clifton Extension Railway The Clifton Extension Railway initially ran from to Narroways Hill Junction with what is now the Cross Country Route north through Bristol, then part of the Great Western Railway; and over a viaduct from Narroways Hill to the Midland Railway's Bristol to Gloucester line near . The line was managed by the Clifton Extension Railway Joint Committee, but in 1894 responsibility was passed to the Great Western & Midland Railways Joint Committee. Services began to Clifton Down on 1 October 1874. The initial service provided by the Midland Railway was between Clifton Down, Fishponds and , where passengers could change for services to Bath, Birmingham and other Midland destinations. The Great Western provided services from Clifton Down to , the city's major station, where passengers could change for trains to London, Exeter and Wales, among others. The Great Western also provided occasional through services to . There were a total of 23 trains in each direction between the two companies Monday-Saturday. On Sundays, there was no Midland service, but seven Great Western trains. The fare to Temple Meads was 6d first-class and 3d third-class. The Clifton Down Tunnel, the final link to the Bristol Port
