Question to the Department for Transport:

To ask the Secretary of State for Transport, what was the cost to the public purse of rail enhancements in control periods (a) 2014-19, (b) 2009-14 and (c) 2004-2009.

Due to changes in the way that rail enhancements are delivered and spend accounted for, it is challenging to provide accurate and consistent information on the cost to the public purse prior to 2010. The following provides information in a consistent price base (April 2022 to March 2023 prices) from a consistent source, for all enhancements spend excluding HS2 in the time periods requested. Note the figures reflect enhancements spend across Great Britain but rail infrastructure in Scotland is a devolved matter.

A) 2014-2019 - £21,627m.

B) 2009-2014 - £15,183m – note that information for Network Rail enhancements spend is not available for the year April 2009 to March 2010.

C) 2004-2009 – comparable information on enhancements spend is not available for this period.
