Mr. Howard: To ask the Secretary of State for Transport, Local Government and the Regions (1) what estimate he has made of the total potential liabilities to the Exchequer which will arise from underwriting the contingent liabilities of the public-private partnerships for London Underground, as proposed in the letters of comfort and Minute from the Secretary of State for Transport, Local Government and the Regions to the partners in the PPP presented to Parliament on 21 March 2002; and how those liabilities will be treated and presented in the national accounts; 
Mr. Spellar [holding answer 10 April 2002]: My right hon. Friend the Secretary of State's Minute to Parliament explained that the proposed comfort letters would cover a wide range of obligations on London Underground under the PPP contracts. In normal circumstances, the letter recognises the annual payments that will be made by London Underground to the infrastructure companies for the successful delivery of the required services, However, it also recognises that, in the unlikely event of an infrastructure company persistently and materially defaulting on its obligations in a way which leads to a termination of the PPP, then any funds put up by shareholders in the infrastructure company would be wholly at risk. In addition, an 'underpinned amount' would become payable to the lenders to the infrastructure

company concerned. This is capped at the total value of the third party debt and has a floor of 95 per cent. of that amount.
The contingent liability will be to repay some or all of the debt that has already been invested in the improvement of the Tube. The potential size of the payment will therefore depend on the amount of debt that has been invested at the time the underpinned amount becomes payable.
The Department's Resource Accounts are drawn in accordance with the Treasury Resource Accounting Manual, which takes account of all financial reporting standards pronounced by the Accounting Standards Board. The contingent liability arising from any letters of comfort would therefore be recorded as a Note to the Department's Resource Accounts.
Mrs. May: To ask the Secretary of State for Transport, Local Government and the Regions (1) what is the estimated increase in use of diesel trains for rail freight use over the lifetime of the 10-year plan; 
(3) what volume of rail freight traffic is hauled by (a) electric and (b) diesel locomotives. 
Mrs. May: To ask the Secretary of State for Transport, Local Government and the Regions what is the estimated number of journeys made per month by road hauliers (a) to transfer freight onto the rail network and (b) to transfer freight from the rail network to its final destination in each of the last five years. 
Miss McIntosh: To ask the Secretary of State for Transport, Local Government and the Regions what compensation is being given to rail freight operators as a result of disruption to rail freight facilities through the Channel tunnel. [49033R]
Miss McIntosh: To ask the Secretary of State for Transport, Local Government and the Regions what estimate he has made of the impact on his ten-year transport plan of the rail freight disruption through the channel tunnel since November 2001; and if he will revise his estimated increase of rail freight.

Mr. Jamieson: The Strategic Rail Authority's (SRA's) Freight Strategy proposes a number of initiatives for increasing use of rail freight in Greater London. The SRA is also working with Transport for London and its London Sustainable Distribution Partnership to identify opportunities for sustainable urban distribution.
Mrs. May: To ask the Secretary of State for Transport, Local Government and the Regions what the estimated environmental benefit is in increasing the volume of rail freight traffic by (a) 10 per cent., (b) 20 per cent., (c) 30 per cent., (d) 40 per cent., (e) 50 per cent. and (f) 60 per cent. by 201011. 
Mr. Byers: The environmental effect will vary depending on how the increase in the volume of rail freight traffic is achieved. An increase in rail freight will, in general, cause an increase in emissions from the rail sector. However, to the extent that this is achieved through modal shift there will be some offsetting benefits, reducing the impact of transport on the environment.
Mr. Collins: To ask the Secretary of State for Scotland on how many occasions since 1 May 1997 (a) departmental and (b) non-departmental special advisers have travelled abroad in an official capacity; and if she will list the total cost, including (i) travel, (ii) accommodation and (iii) subsistence allowance, for each occasion.
