To ask the Secretary of State for the Environment, Transport and the Regions if he will make a statement on(a) train, (b) signal and (c) track failures in each of the last 10 years for the Northern Line of London Underground. [32636]

Year Trains Signal Track
1994–95 3,044 179 150

Notes:

Northern line has recorded the failures on the following basis:

Trains—all failures causing delays of two minutes or more.

Signal—all failures causing delays of two minutes or more.

Track—average impact in seconds per train per round trip journey (track failures during service hours are rare; any failures are generally detected early and result in the application of temporary speed restrictions).
