A branch line serving Bradford on Avon was initially planned as part of the Wilts, Somerset and Weymouth Railway, a broad gauge railway, supported by the Great Western Railway, also a broad gauge railway, in preference to the plans of the London and South Western Railway, a standard gauge railway, which wanted to expand its territory westwards. The proposed line was to run between Weymouth and Bristol. The WS&WR was authorised by Act of Parliament in June 1845, and Isambard Kingdom Brunel, already the engineer of the GWR, was appointed engineer of the new railway. The development of the WS&WR was part of the Gauge Wars.
Construction
The new station buildings were completed by 1850, and also included a goods shed, although the railway tracks were not added until later. The main station was built to the most elaborate of the standard designs used by Brunel, resembling a lodge or estate house of the period, but used local Bath stone, rather than the more commonly used bricks and mortar.
Operation
Financial difficulties slowed the progress of the WS&WR and only twelve miles of the line had been completed when construction was halted. The GWR took control of the WS&WR in a bid to complete the line, but soon wanted to abandon plans to build the branch lines, including the Bradford on Avon branch, to reduce costs. This aroused local opposition from local investors and a lawsuit in 1852 compelled the GWR to complete the Bradford branch. The station finally opened in 1857, with a service of five trains each day each way.
Technical developments
With the development of signalling systems by the GWR, a signal box, with a 30-lever frame, was built to the west of the station and goods shed in 1877. At the same time another signal box, controlling the Greenland Mills level crossing to the east of the station. Although the station was conceived in the gauge wars of the 1840s, the line was finally converted to standard gauge between 18 and 22 June 1874.
Decline in traffic
The goods yard was closed to traffic in 1964, but was used for coal deliveries for another year. In 1966 the signal box was closed and demolished. In the same year Dr Beeching recommended that the line should remain open, but with a modified passenger service.
