Chiltern Railways transition to public ownership

Chiltern Railways is transitioning from private operation under Arriva to public ownership as a subsidiary of DfT Operator Limited. This move, scheduled for 20 September 2026, marks the tenth rail company to be brought under the control of Great British Railways as part of a government renationalisation programme.

To support the transition, the government has announced several service and infrastructure improvements. Starting in December, the operator plans to introduce 25 additional weekday services, adding approximately 10,000 extra seats per weekday and establishing half-hourly services on the Chiltern Main Line between London and Birmingham.

Fleet upgrades include a £12 million refurbishment of the Class 168 fleet to provide improved Wi-Fi, power outlets, and USB charging. Additionally, six new Chiltern Explorer trains will be introduced to provide better accessibility and air conditioning. A new policy regarding cancellations will also allow passengers to use alternative operators at no extra cost if their service is cancelled and an alternative departs within two hours.
