Infrastructure wrong side failures

This measure comprises the number of higher risk (hazard index of 50 or above) infrastructure failures.

The table below shows the number of infrastructure high hazard incidents for 2015/16 compared to previous years.

These incidents are reviewed within the business and information for action shared across the routes including lessons learnt and how we can improve infrastructure reliability and safety of the assets.
