LRTT1035 LRV Systems II
This is the second course in a series covering the theory and operation of Light Rail Vehicle (LRV) systems. The course covers these systems from both mechanical and electrical perspectives. Systems covered include propulsion, braking, suspension and sanding. Theory and troubleshooting techniques are taught using LRV manufacturer-supplied manuals and electrical schematics.
Course Requirements and Evaluation
Refer to Course Syllabus for detailed information regarding the requirements and evaluation standards for this course. The Course Syllabus will be distributed the first week of the course.
