What we do

We regulate the rail industry's health and safety performance, we hold Network Rail and High Speed 1 (HS1) to account and we make sure that the rail industry is competitive and fair. We are also the monitor of Highways England and we have economic regulatory functions in relation to railways in Northern Ireland and for the northern half of the Channel Tunnel, situated in the UK.
