A lack of compliance around communication systems led to two track workers being struck by a wagon near Port Glasgow station, according to an investigation by the Rail Accident Investigation Branch (RAIB).
One worker was trapped between the wagon and a lifting beam of another crane and suffered serious injuries; the second was also trapped and suffered minor injuries.
The wagon, propelled by a rail-mounted crane, was being used as part of a possession to oversee the renewal of a section of track at Port Glasgow, Inverclyde, on 15 March 2025.
At approximately 20:30, the two workers were standing near the track discussing the placement of a track panel being lowered. The propelling crane and wagon were being moved to collect the piece and set it down.
Radio reliant
The investigation reveals the operator of the propelling crane was unable to see in the direction of travel, relying on radioed instructions from a worker on the ground. This worker issued a stop command that was not received, and the wagon continued its journey with the two workers unaware of its approach.
It was also found that there was no lighting at the leading end of the propelled wagon, which could have alerted staff.
The RAIB highlighted three learning points relating to staff compliance: a requirement to start work after being briefed by a certified occupational safety specialist; a requirement for lighting on wagons in possessions; and the application of safety‑critical communication procedures.
