Establish track geometry and position

URN: SEMPW408
Business Sectors (Suites): Rail Engineering
Developed by: NSAR
Approved: 2024

Overview

This standard is about establishing track geometry and position and covers the methods that are used to gather site information, set out/measure and calculate/mark out, the geometrical requirements within specified tolerances.

You will be required to establish track geometry and position through a variety of engineering methods. You will understand the range of geometry and positioning issues that may arise and ways to respond to them to establish track geometry.

The level and extent of responsibility include acquiring the necessary amount of technical knowledge from a diverse range of sources.

Advice from other relevant people should be sought where needed. You will be able to take responsibility for the quality of your work. The quality standards and accuracy to be achieved will be in line with your organisation's procedures.

You will be expected to work within approved procedures and specifications and will work within the limits of your own responsibility.

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying problem-solving techniques and procedures when establishing track geometry and position.

You will comply with any organisational procedures, and legislative or regulatory health, safety and environmental requirements applicable when establishing track geometry and position.

This standard is for all technical staff carrying out permanent way engineering activities.


Performance criteria

You must be able to:

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 source and follow the appropriate schedules, diagrams and related specifications for the work being carried out as approved by your organisation
P4 identify and confirm the objectives to be achieved
P5 assess and analyse the work circumstances and their technical implications
P6 identify technical requirements that could deliver the specified objectives
P7 select and specify for implementation the most appropriate technical requirements to achieve the objectives
P8 use a range of measurement instruments and equipment to establish the position of railway infrastructure in relation to a known or temporarily established datum
P9 identify, analyse and report those requirements which cannot be achieved
P10 prepare appropriate documentation to update on progress and report completion of activities in line with your organisation's procedures
P11 address problems within your control and report unresolved issues
