The purposes of the act include: • the creation of the
Rail Accident Investigation Branch • the replacement of the
Rail Regulator by an independent regulator funded by the government rather than the rail industry, the
Office of Rail Regulation. • the creation of a
police authority for the
British Transport Police (BTP) • allowing the BTP to recruit
police community support officers (PCSO) under the
Police Reform Act 2002 which previously only extended to
territorial police forces • giving the BTP
"statutory authority over the railway" • the introduction of alcohol limits on the crews of water-borne vessels and aircraft in line with those already existing for railway staff • other miscellaneous matters affecting railway, air and road transport The act facilitated the transfer of the London Underground to Transport for London. ==Extent==
