Fundamentals of Electric Rail Vehicle Systems Design, Procurement, Operations, and Maintenance

See upcoming dates

Course Overview

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
