Great British Railways Transition Team (GBRTT)

The work achieved at GBRTT made the case for reform, demonstrated the potential to work in a more joined-up way before Great British Railways is fully realised, and laid the foundations for an integrated railway in the future. This has been achieved through working with a whole-industry mindset in close collaboration with our partners including in the Department for Transport, Network Rail and Rail Delivery Group. GBRTT ceased to exist as an Arm’s Length Body on 1 April 2025. However, there are important activities and programmes that need to continue, which are being carried out by three core teams - Customer & Revenue Growth, Industry Finance, and Fares Ticketing & Retail - alongside the work of the partnerships and projects teams. These teams will work across the whole industry.
