It is 113 miles 63 chains (183.1 km) down the line from London Paddington and is situated between Oldfield Park and Bristol Temple Meads stations.

[1] 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.

[2] Between 1841 and 1851 it had the possibly unique distinction, for a railway station, of featuring a Roman Orpheus mosaic set into a floor.

[4] The trackbed of this can still be seen opposite the entrance to the station car park, which is now a public walking route into the housing estate on what was the Somerdale sports fields.

Direct destinations include: Brighton; Southampton Central; Weymouth; Cardiff; Bath Spa; Gloucester; and Bristol Temple Meads.

[10] Passengers wishing to travel to London Paddington during the off peak hours should change at Bath Spa or Bristol Temple Meads.

Keynsham is also a stop on a Parliamentary train that runs on weekdays to Filton Abbey Wood from Bath Spa, via Bristol West Curve.

[11] Until the December 2021 timetable change, Keynsham was a stop on South Western Railway's London Waterloo to Bristol services.
