Carry out installation of signalling equipment

This standard identifies the competencies you need to install signalling systems and equipment. The signalling equipment in this standard can be for overground or underground rail transportation systems and can apply to the European Train Control System (ETCS).

You will be required to use the appropriate tools and equipment throughout the installation activities, apply a range of installation methods and techniques to position, level and align the equipment and make connections as appropriate to the equipment installed. Where appropriate, you may also work with computers or electronic controllers, making connections, installing hardware and loading and updating software. The installation activities will include making checks and adjustments, in line with your permitted authority, and working with others to ensure that the installed equipment functions to the required specification.

On completion, you will ensure the work area is cleared of all tools, equipment, and materials, and complete job documentation accurately. You will be expected to work to instructions, alone or in conjunction with others. The installation activity may be carried out as a team effort, but you must demonstrate a significant personal contribution to the installation activities to satisfy the requirements of the standard and you must demonstrate competence in all the areas required by the standard.

Safety is a key theme; you must practice and demonstrate safe working methods, understanding and implementing necessary precautions to protect yourself and others.

P1 maintain safe working practices and comply with all relevant health and safety regulations, directives, and guidelines
P2 identify any necessary changes to safety requirements upon site arrival and report to the relevant person(s) without delay
P3 locate and identify the equipment, components and cables to be worked on
P4 source and interpret all relevant diagrams and specifications for the installation activities being carried out
P5 identify and analyse discrepancies in information and take the appropriate remedial action
P6 carry out all installation activities within the limits of your own authority, responsibility and so that the work does not interfere with any operational railway systems
P7 select and use the correct tools and equipment for the installation and check that they are in a safe, usable and calibrated condition
P8 install, position, secure and label equipment, components and cables in line with installation specifications and standards
P9 run, secure, terminate and label wires and cables in accordance with the installation
P10 ensure that the installation is complete and that all components are free from damage
P11 complete the installation integrity checks in line with your organisation's procedures and confirm the completed work is to specification
P12 report any instances where the installation activities cannot be completed
P13 complete all relevant documentation in line with your organisations procedures
P14 address problems within your control and report unresolved issues
