Government spending on the railway for the year ending 31 March 2009 is currently being audited. Subsidy paid along with premiums received from Train Operating Companies for the year 2007-08 is published in National Rail Trends (NRT) which also sets out the amount of subsidy per passenger kilometre. The next National Rail Trends yearbook will be published by the Office of Rail Regulation later in the year and will include the data requested. Copies of the latest version are available in the Libraries of the House.
