Level crossings, infrastructure and vehicles

Railway infrastructure consists primarily of the tracks, formation and supporting structures (bridges, viaducts and tunnels), stations and electrified lines. Signalling and train control equipment also form part of the infrastructure. 

Under health and safety law, we have powers of investigation and enforcement to ensure that railway operators are controlling risks posed by rolling stock operations and infrastructure, so far as is reasonably practicable.
