Rail regulation

We are the economic regulator for railway infrastructure (Network Rail, HS1 and the northern half of the Channel Tunnel, situated in the UK). We are the health and safety regulator for the rail industry as a whole – including mainline, metro, tramways and heritage railways across Britain; and the industry's consumer and competition authority.

Find out about how we prioritise our activities.

Health and safety

We regulate health and safety for the entire mainline rail network in Britain, as well as London Underground, light rail, trams and the heritage sector.

Economic regulation

We regulate Network Rail and other railway networks separate to the national network operated by Network Rail including the Channel Tunnel and High Speed 1.

Protecting consumers

We work to ensure that the rail market is fair – for passengers, freight customers, railway operators and taxpayers.

Promoting competition

We work to ensure that rail markets are competitive and fair – for passengers, freight customers, railway operators and taxpayers.
