Overview

On Wednesday 3rd April 2024, Network Rail staff were replacing a section of rail which involved carrying out a stress restoration at Stanton Gate on the Erewash Valley line.

During the activity a retaining bolt sheared off on the Enerpac RP70AE100 stressing kit and a member of the welding team staff was struck by an extension strip of the kit, causing minor injuries.
