Passenger numbers fluctuated until 2005–06, when the Office of the Rail Regulator estimated that the total number for that year was just above 70,000.
The number of passengers increased rapidly to 2015-16 was more than 271,000, but has since fallen to 232,000 following the opening of Oxford Parkway.

More than 250 passengers a day come by car, but the original car park had only 50 spaces and by 2011 it had been overwhelmed.
In August 2011 First Great Western and a house-building company jointly proposed a new development on a green field site next to the station that would provide new homes and a new 191-space car park.
This was officially opened in July 2013, by which time it was already more than half-full each weekday.
In November 2014 the Cotswold Line Promotion Group found 204 vehicles parked in the 191-space second car park and reported that it "was being used beyond capacity on most weekdays".

Plans were announced to increase services from Hanborough Station, by Great Western Railway.
A launch event was held in Witney, at which GWR's managing director Mark Hopwood said that the investment needed was £275 million.
Double tracking would be reinstated between North Oxford and Long Hanborough and two disused platforms reopened.
The local constituency MP and Prime Minister David Cameron told delegates at the meeting " am utterly convinced of the necessity of investing in this line.
I will do everything I can to give this vision a boost"
A new ticket office was officially opened in August 2019 as part of a £315,000 investment in the station.
This will be open on weekdays.
