RDG currently provides a range of critical cross-industry functions, such as National Rail Enquiries, systems for ticketing and retail, and cross-sector co-ordination. The expertise and systems to deliver these functions will remain essential in the new structure. Great British Railways will take responsibility from RDG for the functions it needs in order to act as an integrated guiding mind across the rail network. This will not affect the ability of train operators and other members of RDG to maintain their own independent trade association.
