Passenger safety

Definition

Passenger safety is measured by the Passenger Safety Indicator (PSI), which incorporates train accident risk data and the weighted number of personal injuries to passengers.

The first element of the PSI, train accident risk data, is taken from the Precursor Indicator Model (PIM). Produced by the Rail Safety and Standards Board (RSSB) every period, the PIM provides a guide to the current train accident risk profile and the trends in this profile. It calculates this using precursor events data from nine main areas (infrastructure operations, signals passed at danger, objects on the line, track, earthworks, signalling, structures, level crossings and train operators failure).

The second element of the PSI is the weighted number (fatalities and weighted injuries (FWI) measure) of personal injuries to passengers, at station level crossings and Network Rail managed stations, as reported in Safety Management Information System (SMIS). This metric is normalised per billion passenger kilometres.

Commentary

In 2017/18 there were 34 Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) injuries to passengers which is a 7 per cent increase compared to the previous year. ‘Slips, trips and falls’ both on platforms and escalators are the largest primary causes of accidents at Network Rail managed stations. The exceptionally poor weather conditions at the beginning of 2018 may be contributing factor in the rise of the number of passenger injuries.

In the past nine years, there have been no passenger or workforce fatalities as a result of a train derailment or collision. We are today the safest major mixed use railway in Europe and one of the safest in the world.
