The curved Brill platform at Quainton Road. The short stretch of rail from this platform is the only surviving part of the Brill Tramway.
While other closed stations on the former MR lines north of Aylesbury were generally demolished or sold, in 1969 the Quainton Railway Society was formed to operate a working museum at the station. On 24 April 1971 the society absorbed the London Railway Preservation Society, taking custody of its collection of historic railway equipment.
[note 15] The station was maintained in working order and used as a bookshop and ticket office, and the sidings—still intact, although disconnected from the railway line in 1967
—were used for locomotive restoration work.
The Quainton Railway Society, which operates the station as the
Buckinghamshire Railway Centre, restored the main station building to its 1900 appearance. A smaller building on the former Brill platform, once a shelter for passengers waiting for Brill and down trains, was used first as a store then as a shop for a number of years before its current use to house an exhibit on the history of the Brill Tramway. A former London Transport building from
Wembley Park was dismantled and re-erected at Quainton Road to serve as a maintenance shed. From 1984 until 1990, the station briefly came back into passenger use, when special Saturday Christmas shopping services between Aylesbury and
Bletchley were operated by
Network SouthEast on Saturdays only, and stopped at Quainton Road.
 From August Bank Holiday 1971 until the 1987 season, and again from August Bank Holiday 2001 the station has had special passenger trains from Aylesbury in connection with events at the Centre - these shuttles now run regularly each Spring and August Bank Holiday weekend.
The former Oxford Rewley Road station building following its reconstruction at Quainton Road
Rewley Road, the Oxford terminus of Harry Verney's Buckinghamshire Railway and of the
Oxford to Cambridge Line, closed to passengers on 1 October 1951 with trains diverted to the former GWR
Oxford General, the current Oxford station. In co-operation with the
Science Museum, Rewley Road was dismantled in 1999, the main station building and part of the platform canopy being moved to Quainton Road for preservation and improved visitor facilities with the main shop and office of the Buckinghamshire Railway Centre, thus maintaining it as a working building.
 A number of former Ministry of Supply food warehouses in what is now the extended Down Yard have been converted for various uses by the Society, including storage and exhibition of rolling stock.
Although the Buckinghamshire Railway Centre's steam trains run on the sidings which were disconnected from the network in 1967, the station still has a working railway line passing through it, used for occasional special passenger trains from Aylesbury in connection with events at the Centre. Regular freight trains are mainly
landfill trains from waste transfer depots in Greater London to the former
brick pits at Calvert.
As one of the best-preserved period railway stations in England, Quainton Road is regularly used as a filming location for period drama, and programmes such as
The Jewel in the Crown, the
Doctor Who serial
Black Orchid and
Midsomer Murders have been filmed there.
 As of 2010 the Buckinghamshire Railway Centre are negotiating for a reconnection of the link between their sidings and the main line to allow their locomotives to run to Aylesbury when the line is not in use by freight trains, and to rebuild part of the Brill Tramway between Quainton Road and Waddesdon Road.
