Report 14/2015: Class investigation – protection irregularities

RAIB has released its report into irregularities with protection arrangements for track workers during infrastructure engineering work.

Protection irregularities


RAIB has investigated a number of accidents involving track workers on Network Rail’s infrastructure and has identified track worker safety as an area of particular concern in recent annual reports.

RAIB has also become concerned at the number of operating irregularities associated with the protection of those carrying out engineering work, particularly where protection was planned to block the line to traffic. This is because, in different circumstances, these irregularities could have led to harmful, and possibly fatal, outcomes.

RAIB observed the regular occurrence of these operating irregularities in the daily incident reports produced by Network Rail’s National Operations Centre (NOC). As a result, it decided to collect information over a two-year period (April 2011 to April 2013) to understand more. This report describes analysis that the RAIB has carried out based on this information, and its investigation of the safety issues that this identified.

The data analysis showed that most of the reported operating irregularities were potentially harmful and that their occurrence was neither infrequent nor reducing. A systematic review of these was then undertaken to identify the various safety issues that would need to be addressed to prevent them occurring and leading to harm.

RAIB is aware that Network Rail is currently planning and implementing a major track safety initiative known as ‘Planning and Delivering Safe Work’ (PDSW). The investigation has sought to understand this and has established that Network Rail intends that PDSW will address a number of the safety issues identified.

However, RAIB has observed that the initiative is currently only in the early stages of implementation and that the envisaged benefits have yet to be demonstrated. It has also observed that the initiative is intentionally focused on the roles of those working on site. This means that it will not have significant benefits in areas where risks may be created by people in a number of other roles that are important in safeguarding those carrying out work on the railway.


As a consequence of this investigation RAIB has made two recommendations addressed to Network Rail. They are concerned with:

  • monitoring and verifying the benefits obtained from the PDSW initiative
  • developing an action plan to reduce the risks associated with railway roles that are outside the scope of the PDSW initiative

Notes to editors

  1. The sole purpose of RAIB investigations is to prevent future accidents and incidents and improve railway safety. RAIB does not establish blame, liability or carry out prosecutions.

  2. RAIB operates, as far as possible, in an open and transparent manner. While our investigations are completely independent of the railway industry, we do maintain close liaison with railway companies and if we discover matters that may affect the safety of the railway, we make sure that information about them is circulated to the right people as soon as possible, and certainly long before publication of our final report.
