Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessments she has made of potential duplication of functions between Network Rail and Great British Railways, and their (a) cost and (b) impact, during the transition period.

Network Rail and its functions will become a foundational part of Great British Railways (GBR) as it is stood up. The GBR design process is underway, considering how all functions in Network Rail, DfT Operator, publicly-owned train operating companies (TOC) and parts of the Rail Delivery Group (RDG) should transfer to GBR. The costs of implementation are being considered as part of the business case for GBR setup.
