This course will cover the basic design criteria of the rail car, its sub-systems and integration. We will discuss factors that affect the design, sizing, manufacturing and maintenance of the sub-systems of the rail car, including their integration with other sub-systems to work as one complete train. Various factors affecting reliability, accessibility and maintainability will be addressed.
After attending this course, you will be able to:
- Describe the fundamental concepts of electric rail transportation, including propulsion, braking, power, and control
- List the physical systems that comprise a vehicle
- Differentiate between systems used in light, heavy and commuter rail applications
- Explain a train control system architecture
- Describe the integration of multiple systems and vendors’ products within a complete vehicle system
- Develop a fleet procurement plan including proposals, design validation and verification of performance and reliability through testing
- Create a plan to integrate new vehicles into existing operations
- Describe the issues pertinent to the maintenance of new vehicle systems
