• Cherwell Valley line: there is a single daily parliamentary service operating on the Cherwell Valley Line from Oxford to Banbury, operated by Chiltern Railways. This service runs on Tuesdays to Saturdays just after midnight and calls at Tackley, Heyford and Kings Sutton - the three intermediate stations on the line. There is no corresponding return service heading towards Oxford. This service exists to maintain route knowledge for Chiltern Railways' drivers. Regular services on the line are operated by Great Western Railway and CrossCountry.
• New North Main line/Greenford branch line: the company also operated a weekday parliamentary service to and from West Ealing in the late morning. Until December 2018, these services ran to and from London Paddington. They were then diverted to West Ealing following closure of the easternmost section of the New North Main line for High Speed 2 construction. The parliamentary service used to run a return service, with the returning service terminating at High Wycombe. At the start of the COVID-19 pandemic, the service was suspended until December 2021. As of December 2022, the service no longer runs and has been replaced by a bus service.
