Introduction to Traction Power and OCS Systems

This course introduces the key components and concepts behind electrically powered rail systems, including traction power systems and overhead contact systems. Learners will explore power feeding schemes, pantograph interfaces, and the differences between AC and DC OCS components. With access to course materials, instructor support, and a certificate for 2 PDHs, this course is a valuable first step into the world of rail electrification.

• Engineers and technicians new to rail electrification or transitioning into traction power roles.
• Professionals preparing to take the full 2-day Fundamentals of Traction Power Systems and OCS course.
• Project managers, planners, or consultants seeking a high-level understanding of electric rail systems.

It is highly encouraged you take this course before the 2-day “Fundamentals” course.
