Question to the Department for Transport:

To ask the Secretary of State for Transport, how many rail improvement projects for expanding commuter services on single track sections of rail are (a) ongoing and (b) have been completed in the last 10 years.

Network Rail's Enhancement Delivery Plans sets out funded schemes which are in the process of delivery as part of the Governments £10.4bn enhancement commitment to 2024 and the Department's Rail Network Enhancement Pipeline lists the schemes which are being evaluated for funding. Train operators in the UK are currently operating around 20 million miles a year more passenger services than in 2010/11, a number of which such as the North Cotswolds, Swindon-Kemble and Falmouth Docks lines use single track sections.
