Common Safety Indicators - Assessment of achievement of Rail safety targets for 2021

Date published: 10 March 2023

Safety targets are set to ensure a minimum level of safety is achieved.
The assessment of achievement of safety targets is undertaken using a common set of railway safety data, the Common Safety Indicators (CSIs). CSIs help assess whether railway systems comply with safety targets and facilitate the monitoring of railway safety performance.


This report assesses safety performance of Northern Ireland’s (NI) railway and the achievement of safety targets for the calendar year 2021. This uses CSI data to assess the level of safety associated with six risk categories.
