The Department has not made any specific assessment of the difference between peak and mean aircraft noise levels. This is because the suitability of what measurement is used will depend on the type of noise situation being addressed.
18 Apr 2006 : Column 50W
The Department uses various measures of aircraft noise levels. The departure noise limits at Heathrow, Gatwick and Stansted relate to peak noise 1 and aircraft noise events at the fixed noise monitors (where the limits apply) are measured accordingly.
Mean peak aircraft noise levels are not assessed on a routine basis but would be considered if appropriate andreported in technical studies carried out by the Environmental Research and Consultancy Department of the Civil Aviation Authority. For example, CS Report 9539 Review of the Departure Noise Limits at Heathrow, Gatwick and Stansted Airports" includes statistics broken showing the reference mean levels, standard deviations and other statistical information relating to the peak noise of actual flights. A copy of this report was placed in the House Library.
Derek Twigg: The UK aviation industry has developed and published A Strategy Towards Sustainable Development of UK Aviation". This includes a commitment to deliver continued improvements in airport ground vehicles, along with improvements in supply of ground power services, operational practices and the availability of cleaner fuels. The industry is committed to reporting on progress with this commitment by the end of 2006.
Mr. Greg Knight: To ask the Secretary of State for Transport what property, including railway structures, is owned by the British Railways Board (Residuary) Ltd.; and where the property is located. 
Derek Twigg [holding answer 6 March 2006]: As at 31 March 2005 BRB(R) Limited owned 735 pieces of non operational railway land and property. Details of their location are available on the company's website at www.brbr.gov.uk. This website will be updated in the next two months. The company also has leasehold interests in the following buildings:
These leases were taken out by the British Railways Board prior to the privatisation of the railway in the 1990's and are of a long-term and onerous nature. As such it was not considered appropriate to transfer them to the private sector at privatisation. BRB(R) will routinely exit its obligations under these leases as and when the opportunity arises and where such an exit provides good value for money for the taxpayer.
Mr. Amess: To ask the Secretary of State for Transport what estimate his Department has made of the number of vehicles driving with defective (a) brakes, (b) brake lights, (c) head lights, (d) tail lights and (e) side lights; and if he will make a statement. 
Dr. Ladyman: The information requested is not available. Estimates of drink drive accidents in Great Britain as a whole are published each year in an article in Road Casualties Great BritainAnnual Report". Estimates below Government office region level are not available.
Derek Twigg: A copy of the Greater Western SLC2 will be placed in the Library when it becomes a public document. SLC2, together with the Greater Western franchise agreement with which it needs to be read, is currently going through the statutory exclusions procedure in the Railways Act 1993 (as amended). This must be carried out before SLC2 can be made public by being placed in the Department for Transport's public register.
Mr. Drew: To ask the Secretary of State for Transport what assessment he has made of the implications for heritage railways of the EU directive on Railway and Other Guided Transport Systems (Safety) Regulations 2006; and what representations he has received on this matter. 
Derek Twigg: I laid before Parliament on 17 March 2006 the proposed Railways and Other Guided Transport Systems (Safety) Regulations (ROGS) which implement the safety management aspects of EU Directive 2004/49/EC. An Explanatory Memorandum, Transposition Note and Regulatory Impact Assessment for all sectors of the railway, including heritage railways, accompany the proposed regulations. A copy has been placed in the House Library. Before laying the proposed regulations, I had a constructive meeting with representatives of heritage railways and representatives of the tramway industry on 1 March.
Dr. Ladyman: Tables showing (a) the number of personal injury road accidents which involved one or more hit and run drivers or riders and (b) the resulting fatalities, serious and all injuries resulting from these accidents, for the years 19972004 (the latest year for which figures are available), broken down by police force, have been placed in the Libraries of the House.
