In 1987 Harry Blundred, a former bus driver and controller from Devon, founded both Thames Transit and the Oxford Tube.

The partnership would improved multi-operator ticketing across the City and co-ordinate bus timetables on the four busiest shared routes.

Costing Stagecoach over £100 million in total, it included 26 new VanHool TX Astromega coaches to operate the Oxford Tube service.

[11] The new coaches increased comfort and facilities for passengers including more leg room, 4G WiFi, power sockets and USB ports in selected seats and a brand new audio information system providing passengers with departure and arrival information and the top deck also features a panoramic glass sun roof allowing more natural light into the coach.

[12] In 2020, Stagecoach announced that it would replace their current Tube fleet with 34 new Plaxton Panorama vehicles, built on Volvo B11RLE chassis.

[13][14] In 2023, Stagecoach added services via High Wycombe Coachway, and also starting in Carterton and operating via Witney and Eynsham.

The Stagecoach Gold brand was introduced in Oxfordshire in 2009 with the creation of the first S-Series (Superior Series) routes.

The Gold branded buses feature a special Gold and blue coloured livery along with high-back leather seats and free on-board Wi-Fi (currently disabled due to running costs).

[22][23] Stagecoach Oxfordshire operated route 737 from Oxford Gloucester Green to Stansted Airport under contract to National Express from March 2007 until June 2013.

This is partly due to Oxford's Low Emission Zone, which allows only buses with exhaust systems of at least Euro V standard or better to serve the city centre.
