Track Defects and Track-Train Interactions JEE153


In JEE151 Fundamentals of Track Engineering and in other units you learned about the various components from which track is constructed, some of the defects which can occur in those components, and something of the forces generated by a train traveling along a track. In this unit you’ll be delving much deeper into the types of defects which can afflict rails, sleepers, ballast and the track substructure, as well as how to manage those defects and how to mitigate risks of defects interfering with the passage of traffic on a rail line. Those topics naturally lead on then to a detailed study of the interface between trains and track, which happens all within the wheel-rail contact patch. The management of that patch, its effect upon train behaviour and track forces, and the influence of rail and other track defects in the role of the contact patch, comprise the remainder of the unit’s content. This unit has close relationship with JEE155 Track Design and JEE153 Track Maintenance and Applications.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

About Census Dates

Learning Outcomes

  • Identify and describe important defects in track with a view to mitigating their effects on the life of the track.
  • Describe the growth, detection and consequences of defects in rails to help assure effective rail maintenance.
  • Explain the management and mitigation of risks from track & rail defects, for the safe operation of trains.
  • Define and describe the dynamic interactions and forces between trains and track so that the wheel-rail interface can be managed properly.
  • Explain key characteristics of the wheel-rail interface and its relationship to track alignment and stability for effective design of track.
