The Government works closely with the Welsh Government on the specification and funding of Network Rail’s operations in England and Wales for each five year railway Control Period. The approach we are using to assess the need for investment into rail infrastructure in South Wales will remain unchanged after the UK leaves the EU. We will continue to consider rail investments in line with the Rail Network Enhancements Pipeline (RNEP). Network Rail’s Control Period 6 Strategic Business Plan, covering the period from April 2019 to 2024, states a total proposed investment of £1.34bn in rail across Wales and Borders.
Investment in road infrastructure is a devolved responsibility and would be a matter for the Welsh Government.
