Safety Bulletin - NRB24-06 - Temporary Road Rail Access Panels (RRAP) left on an open line

    Safety Bulletin – NRB24-06 – Temporary Road Rail Access Panels (RRAP) left on an open line.


    On the 25th of April 2024, the first Avanti West Coast service travelling at line speed on the Up Fast line through Kings Langley struck a piece of temporary RRAP which had been left in the fourfoot following emergency OHL repairs during the night. A second train travelling on the adjacent line (Down Fast line) also suffered a cracked windscreen from the impact of the temporary RRAP. There was no one injured, however if there were people on platform it would have caused serious injury or a worst case fatality. This led to significant disruption / cancellations on the West Coast South route.

    The emergency work was completed, and the COSS handed back the site of work to ES at 03.09, declaring the line safe for the passage of trains. The ES handed back the worksite to PICOP at 05.06. Shortly after the possession was given up, 1R00 struck the piece of RRAP.

    Initial investigation found that site lighting was not adequate and a reliance was on head torches.

    There was no system in place to count out and count in the RRAP pieces (approximately 20 pieces in this instance). Although the PIC stated they were not fatigued, they had a busy day before coming into work at night.

    Similar incidents have happened recently in other routes, see Safety advice Ref: NRA23-14 and NRB24-01.


  • Who is responsible for making the site of work safe after work is complete?
  • When working as an ES, COSS or PIC, how do you verify the line is clear for the safe passage of trains?
  • Any materials left on site must be removed from the running line(s), and secured (where required) in a position of safety before handing the site back to prevent damage or injury.
  • When accessing an RRV you should plan to use a permanent or semipermanent RRAP.
  • The work should be planned in line with lighting requirements within risk control sheets, WARA’s and relevant asset standards.
  • It is your personal responsibility to make sure you have adequate rest before work and are fit to work.
