Transport Committee urges clearer detail as government commits to further Railways Bill plans

The House of Commons Transport Committee has welcomed a government commitment to provide additional detail on the implementation of the Railways Bill, while highlighting a number of areas where MPs say greater clarity is still needed ahead of major reforms to the rail system.

The Railways Bill will establish Great British Railways (GBR), a new public body intended to bring together responsibility for rail infrastructure, services and network planning. During its scrutiny of the legislation, the Transport Committee said it identified several gaps in detail around how the new organisation will operate in practice, how decisions will be made, and how the transition will be managed.

Transport Committee Chair Ruth Cadbury said the committee had set out concerns about the level of operational detail currently available in the legislation and supporting materials.

She said the committee had identified “several areas where further clarity was needed during its scrutiny of the Bill”, particularly around how the government expects the transition to Great British Railways to be delivered in stages and how existing rail bodies will be integrated into the new structure.

MPs on the committee have also raised questions about how responsibilities will be divided between the Secretary of State and GBR once the new organisation is established, including the extent to which ministers will be able to issue directions on day-to-day operational matters.

In its response, the government said it would publish further information in the coming months setting out more detail on the implementation timetable, key milestones and the sequencing of reforms ahead of the creation of GBR.

It also reiterated that ministerial direction should not become routine once the new structure is in place, and indicated that such powers would be used only in limited circumstances, such as in cases of significant service failure or wider system disruption.

The Railways Bill, introduced to Parliament in late 2025, forms part of wider plans to restructure Britain’s railways by consolidating infrastructure and service oversight into a single publicly owned body. The government has said the reforms are intended to improve accountability, simplify governance and enhance passenger experience.

Further parliamentary scrutiny of the Bill is expected as it continues through its legislative stages.
