It is 107 miles 72 chains (173.6 km) down the line from London Paddington and is situated between Bath Spa and Keynsham.

Many new road bridges were necessary to overcome the difficulty posed to local goods traffic by this new railway.

This occurred in the early 20th century when an extra line to a goods yard was laid to the end of the westbound platform.

The majority of Brunel's design for Bath was raised up on a system of earth embankments and stone arches.

To some extent Oldfield Park replaced an earlier station at Twerton,[1] three-quarters of a mile to the west, which had closed, ostensibly temporarily, in the First World War and which had been badly affected by competing bus and tram services.

The limited road and platform access made the handling of bulky goods very difficult.

To the east of the westbound platform a single section of line was added from the Westmoreland goods yard in Lower Oldfield Park.

The 1929 ticket office was constructed of timber on tall wooden piles attached to both the Brook Road bridge and the ground below.

On Sundays there is one train per two hours between Cardiff Central and Portsmouth Harbour, and one train per two hours between Bristol Temple Meads and Westbury[12] There is a ticket machine at the station where passengers can collect pre-booked tickets or buy them on the day.

Until the December 2021 timetable change, Oldfield Park was a stop on South Western Railway's London Waterloo to Bristol services.
