It was commissioned in 2014 to inform our early preparatory work for PR18.

Options for capacity measures and metrics, report by TRL, published 7 March 2017. The objective of this report was to find a set of measures that could provide both a means of tracking changes in the provision and use of the existing rail infrastructure capacity and a basis for incentivising Network Rail to increase capacity, whilst maintaining the right balance between capacity usage and performance.
