Chiltern Railways will move into public ownership on Sunday 20 September, becoming the sixth train operator to transfer under the Government’s rail reform programme as preparations continue for the creation of Great British Railways (GBR).
The operator, which connects London Marylebone with destinations across Buckinghamshire, Oxfordshire, Warwickshire and the West Midlands, is set to benefit from a package of passenger-focused improvements designed to increase capacity, enhance reliability and modernise infrastructure across the network.
The transition forms part of the Government’s wider ambition to create Great British Railways, bringing train operations under a more integrated structure and aiming to deliver a railway that is easier for passengers to use.
One of the most significant changes for customers will arrive with the December timetable, when 25 additional weekday services are introduced. The enhanced timetable will include a half-hourly service throughout the day on the Chiltern Main Line between London and Birmingham, creating almost 10,000 extra weekday seats, around 5,000 additional Saturday seats and more than 3,000 extra Sunday seats.
The operator will also continue its fleet modernisation programme. Six additional Chiltern Explorer trains are scheduled to enter service in December 2026, completing a fleet of 13 modern units. The trains will provide greater capacity alongside improved accessibility, air conditioning and enhanced onboard Wi-Fi.
Alongside the new train programme, Chiltern’s existing Class 168 fleet will undergo a £12 million refurbishment, delivering upgraded Wi-Fi, power and USB charging at every seat, together with refreshed interiors by 2028.
Passengers can also expect improvements at stations across the route, including refurbished toilet facilities, painting programmes, deep cleaning and graffiti removal. At Haddenham & Thame Parkway, 200 previously unavailable parking spaces will be brought back into use, improving access for rail users.
Further investment will be directed towards customer information and wayfinding, with new signage planned at five of the operator’s busiest stations, alongside upgrades to information screens, help points and accessibility infrastructure.
The move into public ownership is also expected to support delivery of East West Rail, with ministers highlighting closer industry collaboration as a key benefit of the transition.
From Sunday, Chiltern customers whose train is cancelled will additionally be able to use another operator’s service without incurring extra costs, providing greater flexibility during disruption.
Rail Minister Lord Hendy said:
"From this Sunday, Chiltern Railways passengers will be travelling on rail services back in public hands.
“Every transfer into public ownership gives us the chance to tackle the bread-and-butter issues people care about – more frequent, comfortable trains that turn up on time.
“As we set up Great British Railways, we're putting passengers first. It will not happen overnight, but we will build a railway the country can trust and rely on and that will create growth, jobs and homes.”
Tony Baxter, Interim Managing Director of Chiltern Railways, said:
“Sunday is a significant milestone for Chiltern Railways and we look forward to working together with the wider rail industry to deliver a better railway for everyone in Great Britain.
“Over the next 12 months, our customers in London, Buckinghamshire, Oxfordshire, Warwickshire and the West Midlands will benefit from more new trains, more services, thousands of additional seats, improvements to stations and on-board facilities and the ability to use their ticket on other operators when faced with disruption – customer improvements made possible thanks to years of planning, dedication and hard work by Chiltern colleagues.
“Public ownership will further strengthen that progress through closer collaboration across the industry, helping us share best practice, drive innovation and focus on what matters most to customers, businesses and communities across our network.”
Chiltern Railways' transition comes ahead of Great Western Railway's planned move into public ownership on 13 December 2026, with the Government aiming to complete its wider programme by the end of 2027.
