Benchmarking of Network Rail’s costs

Understanding the drivers of Network Rail’s expenditure, including the reasons for changes over time is central to our work in assessing the scope for efficiency improvements. To achieve this, we use a range of complementary approaches including bottom-up assessments of Network Rail’s business plans and performance, and top-down cost benchmarking using statistical (econometric) methods. 

This cost benchmarking section of our website summarises our econometric benchmarking of Network Rail’s expenditure.
