The station was opened on 31 August 1840 with the completion of the Great Western Railway line between Bristol and Bath. It was renamed Keynsham and Somerdale on 1 February 1925 with the opening of the Fry's chocolate factory at Somerdale, which had its own siding. The station was rebuilt in 1931 to accommodate longer trains bringing in workers who had transferred from a factory in Bristol belonging to the company. Between 1841 and 1851 it had the possibly unique distinction, for a railway station, of featuring a Roman Orpheus mosaic set into a floor. This had been found at Newton St Loe, and is now in Bristol City Museum and Art Gallery. Keynsham is the nearest station to the village of Saltford, which until 1970 had its own station. The station's name reverted to Keynsham on 6 May 1974. By this time many workers had relocated to Keynsham, or commuted by car. The factory had its own rail system which was connected to the mainline. The connection to Fry's chocolate factory was taken out of use on 26–27 July 1980. The trackbed of this can still be seen opposite the entrance to the station car park. The station was rebuilt in 1985 as a joint project between British Rail and Avon County Council. The rebuilding provided a new brick built shelter on platform 2, a new footbridge and the enlargement of the car park. Further construction work began in mid-2009. In 2011 a campaign group was formed to gain improved access for the disabled at the station. Recently a new disabled access ramp was built which provides wheelchair access between the footbridge and Platform 1. In addition to this, dot matrix display boards have been put up on both platforms. These displays are accompanied by audio announcements.
