LRTT1045 LRV Systems III
This is the third course in a series covering the theory and operation of Light Rail Vehicle (LRV) systems. The course covers LRV systems from both mechanical and electrical perspectives. Systems covered include trucks and the car body. Theory and troubleshooting techniques are taught using LRV manufacturer-supplied manuals and electrical schematics. In addition, this course discusses methods for lifting vehicles both in a repair shop and in the field to re-rail. This course also reviews crane safety and hand signals. Because of the inherent dangers in this work, particularly in lifting heavy loads, safe work practices will be emphasized throughout this course.
