I refer the hon. Member to the answer on 25 November 2008, Official Report, column 1189W.
The Department for Transport does not hold the information at the level of detail requested. However, Network Rail is the custodian of timetable and performance data for the rail industry, and will be able to provide this information. The hon. Member should contact Network Rail's Chief Executive at the following address for a response to his question:
Iain Coucher
Chief Executive
