GERT8000-HB12 ERTMS Iss 3
Duties of the engineering supervisor (ES) or safe work leader (SWL) in a possession on ERTMS lines where lineside signals are not provided
Synopsis
You will need this handbook if you carry out the duties of the ES or SWL on ERTMS lines.
Summary Of Changes
It is no longer permitted for work in connection with isolations of the AC or DC electrification systems to begin before the work-site marker boards are in position so section 3.3 has been revised to remove reference to this being allowed. The same section has also been reworded to make it clear that no other work can commence within the work site until the PICOP has told the ES that the work site has been granted.
A new section 6.9 has been added describing the actions necessary when a controller of site safety (COSS), designated person (DP) or machine controller (MC) requests line protection for work to be carried out on a rail vehicle.
Section 7.8 has been renamed ‘Manually-controlled level crossing’ to remove gender-specific language.
13/08/2024 - 12m review report recommendation approved by TOM SC in July 24. No further action required.
