The Rail Accident Investigation Branch (RAIB) is investigating a collision between two road-rail vehicles (RRVs) that occurred at around 07:00 on 2 May 2021 while they were travelling in a worksite at Ramsden Bellhouse, between Billericay and Wickford stations in Essex.
They had been used to replace overhead electrification equipment and were on the same line, travelling towards Wickford at the end of a night shift.
The leading RRV was a Mobile Elevated Working Platform (MEWP) and this was being followed by a long reach mobile crane. The two people travelling in the MEWP basket were injured, one seriously.
RAIB’s preliminary examination found no evidence of a fault in either of the machines. Its investigation will determine the sequence of events that led to the accident and include consideration of:
- The processes for ensuring that vehicles travel safely within worksites;
- The processes that govern the hours trackworkers are on duty, the identification of fatigue and how rest periods are managed;
- Any relevant underlying factors.
Once completed, a report on the investigation will be published on the RAIB’s website.
