§ Chris Grayling
To ask the Secretary of State for Transport, Local Government and the Regions what assessment he has made on how Thameslink 2000, South London Metro and the East London line would use common corridors; and whether this can be achieved in a way consistent with the Strategic Rail Authority's goal of reducing the number of operators on key commuter routes in London. 
§ Mr. Spellar
The integrated planning of the southern timetable is being carried out by Railtrack for GoVia, with active involvement from the SRA. The work is focused on maximising the use of the network for all relevant operators.
