Report on near miss between train and track worker at Peterborough


The Rail Accident Investigation Branch (RAIB) has issued a report on an incident at Peterborough station during which a track worker missed being hit by a train travelling at over 100mph by only 2.6 seconds.

It happened at around 10:52 hrs on 20 July 2018. The train involved had just passed through the station and was travelling at 102mph (164km/h) when its driver saw the worker, who was acting as a lookout for a colleague who was conducting an inspection, standing on the same line ahead. The driver immediately sounded the train’s warning horn and applied the brakes. The lookout responded to the train’s horn and moved out of its path about 2.5 seconds before the train reached him.

The RAIB’s investigation found four causal factors:

  • The site lookout was distracted and not adequately observing his distant lookout or looking for approaching trains.
  • He had also chosen to stand on an open line when it was not necessary to do so.
  • The track worker carrying out the inspection, who was also the Controller of Site Safety and responsible for the safety of all the staff involved in the work, was not monitoring the unsafe actions of the lookout at the time of the incident.
  • The distant lookout had left his position before the train arrived because he thought he had been stood down. A distant lookout who was still visible to the site lookout was actually from a different team and was looking out for trains coming in the opposite direction.
Location of the incident at Peterborough station.

Underlying these were two further causes. One was the way in which the work was planned, which defaulted to using the least preferred safe system of work in the hierarchy within Network Rail’s company standard for managing the safety of people at work on or near the line. The other was the fact that the current rules for communication when lookouts are used are impractical, leading to a disregard for the rules and the use of unofficial and uncontrolled practices.

RAIB investigations do not set out to establish blame, liability or carry out prosecutions. They are conducted to establish the facts of what happened so as to prevent future accidents and incidents and improve railway safety.

Five recommendations were made to Network Rail as a result of this investigation:

  1. Change the current rules so that site lookouts default to standing in a position of safety unless this is not practicable to implement the safe system of work;
  2. investigating the common but unofficial use of flag signals by lookouts to communicate, finding ways to improve and control this communication, implementing changes and monitoring the effectiveness of the changes that are made
  3. Clarify to track workers the actions they should take when more than one group wants to work with lookouts in the same place;
  4. Continue the ongoing work of the Network Rail route involved to reduce the use of lookouts for cyclic maintenance tasks;
  5. Reducing the number of cyclic maintenance tasks that are undertaken using lookouts across all of Network Rail’s infrastructure.

The investigation also identified three learning points:

  1. The importance of early use of the train’s horn by drivers to give an urgent warning, which probably averted an accident in this case;
  2. The briefing of lookouts on where to stand while carrying out their duties;
  3. Staff responsible for the safety of the work group not becoming distracted by the work activities to the extent that they are no longer observing the group.

Simon French, chief inspector of rail accidents, commented: “The number of near misses involving trains and track workers which we have seen in recent years is hugely disappointing. The subject of this report is another of these events – in this case the worker concerned moved clear of the line less than three seconds before the train passed him.

Simon French, RAIB

“This narrowly avoided collision between train and man took place during routine inspection work. The catalogue of problems with on-site organisation and communication that we found in this investigation was alarming. Some of the people involved made assumptions about what was happening, and the lookout allowed himself to be distracted from the vital duty of warning of approaching trains.

“The investigation highlights the difficulty of managing effective communications between controllers of site safety and the lookouts that they have placed at locations remote from the site of work. A number of unofficial flag signals were being used to transmit messages, and this was a factor in the Peterborough incident. For this reason, we are recommending that Network Rail investigates the methods of communication that are actually being used in these circumstances and comes up with practical measures that will make life safer for teams working on the track.

“I believe that it is also important that the company continues to work hard to reduce the amount of work that is done under the protection of lookouts. Some of Network Rail’s maintenance managers have shown that smart planning can enable more routine maintenance activities to take place when trains are stopped, so improving safety and making better use of working time.”
