Unit Description and General Aims
This Unit continues the recognition of the need for Rail Civil Engineers to have a sound knowledge and clear understanding of the behaviour of the main components of rail tracks.
The rail is the immediate interface between the train vehicle and the entire supporting system and is, therefore, the element that has the most direct effect on enabling or inhibiting train operations.
Aside from ballast and sleeper rectification as described in the “Ballast, Sleepers and Fasteners” Unit, this Unit examines the costs of rail wear and grinding, the requirement to eventually replace worn rails, and rectification of track geometry – which in combination make up the bulk of maintenance expenditure by the track owner.
In conjunction with the other first year Units, the intent is for this Unit to provide students with detailed knowledge of the key elements of the track superstructure and the important contributions which these components make to the operation of rail systems.
On successful completion of this Unit, students are expected to be able to:
- Check and judge problems associated with the analysis, maintenance, and management of rails in track.
Bloom’s Level 5
- Evaluate information necessary for and appropriate to the solution of those problems.
Bloom’s Level 5
- Test and validate the characteristics of rails and the principles of the selection and maintenance of rails towards the safe operation of trains.
Bloom’s Level 5
- Critically judge the operation of rail-related track structures and evaluate their maintenance requirements.
Bloom’s Level 5
- Plan, generate, and construct appropriate engineering and/or management elements within a major case study incorporating rail and related track structures.
Bloom’s Level 6

|Weighting (% of total unit marks)||Learning Outcomes Assessed|
Word length: 1500
Topic: Specify rail standards, critically judge general issues in rail maintenance and propose solutions.
Type: Case study and Presentation
Word length: N/A
Topic: Focus on a rail case relevant to the student. Investigate the safety issues, test and validate the standards of the rail and evaluate the deterioration.
|Weeks 4||15%||2, 3|
Type: Group discussion and Evaluation
Topic: The student is to contribute progressively to an unfolding discussion amongst their peers in this Unit on a current topic of interest in rail renewal and maintenance. A minimum of four insightful contributions is required.
|Week 7||25%||1, 3|
Word length: 2000-3000
Topic: Prepare a comprehensive engineering report on a case study related to a major rail and related track structures maintenance and/or renewal project, with a view to minimising cost, maximising safety and re-use, and satisfying operational standards and requirements. The report will require careful referencing and be suitable in its format, quality of analysis, and conclusions for decision-making by senior engineers.
Embedded practical component: Students are to research and interact with software simulations for optimized results to be referenced and/or demonstrated in their final report.
