Report on railway asset condition measurement methodology.

The Office of Rail and Road (ORR) contracted SYSTRA Scott Lister UK Ltd (SSL) to evaluate the Composite Sustainability Index (CSI) methodology against infrastructure asset condition measurement methods used elsewhere in the rail sector and in other highly regulated industries. The ORR also wished to determine whether infrastructure asset condition measurement methodologies have advanced significantly since the CSI’s inception in 2014, and the extent to which other asset managers and regulators make use of composite indices to express investment needs.
