Off-site repairs may include but are not limited to: dismantling of equipment into its
lesser components; use of workshop practices such as fabricating, machining, and
welding to return existing components to specification; the rebuilding of equipment
from restored and/or new components; and equipment testing prior to release. It is
typically of a scale not able to be performed with equipment in position. These skills
are covered by unit standard 24028, Repair and adjust mechanical signalling
equipment in position in a rail environment.
4
Off-site repair is to be undertaken on at least three occasions, using one or more
items of mechanical signalling equipment.
5
Operations may:
 be conducted by day or night in all relevant weather conditions;
 be conducted in restricted spaces or exposed conditions or controlled or open
environments;
 involve exposure to chemicals, dangerous or hazardous substances and
movements of equipment, materials and vehicles.
6
Work is performed under minimal supervision, generally within a team environment.

Competenz acknowledges the assistance provided by the Transport and Logistics
Industry Skills Council in permitting unit of competency TDTB4801A, Carry out OffSite Repair, Overhaul and Assembly of Mechanical Signalling Equipment to be used
as the basis for this unit standard.

Definitions
Component refers to any mechanical, electrical, electronic, pneumatic/hydraulic part
or parts assembly used in or in conjunction with any mechanical signalling device or
signalling control mechanism.
Off-site refers to an engineering workshop or similar maintenance facility where
repairs are performed on equipment that has been taken from its usual position
within the rail network.
Organisational procedures refer to documents that include: worksite rules, codes,
and practices; equipment operating instructions; technical specifications/drawings;
non-compliance reports, documented quality management systems; material safety
data sheets (MSDS); maintenance schedules; and health and safety requirements.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
