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.

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.
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.
We work to ensure that the rail market is fair – for passengers, freight customers, railway operators and taxpayers.
We work to ensure that rail markets are competitive and fair – for passengers, freight customers, railway operators and taxpayers.
If a railway operator wants to access the railway network, they have to apply to us for a track access agreement with Network Rail.
