Udemy – Power Supply for Railway Signalling (Indian Railways)

In modern railway networks, a reliable and uninterrupted power supply is the backbone of safe and efficient train operations. Signalling systems — whether traditional relay-based or advanced electronic interlocking — depend on precisely engineered electrical power arrangements to function without failure. This course is designed to provide a comprehensive understanding of the design, operation, maintenance, and troubleshooting of power supply systems specifically tailored for railway signalling applications.

Through a structured and practical approach, you will explore:

• Secondary Cells & Batteries — including lead-acid, low-maintenance, and VRLA technologies, their charging/discharging characteristics, efficiency, maintenance practices, and lifespan.
• Integrated Power Supply (IPS) Systems — components, working principles, SMPS-based designs, protection features, and problem-solving strategies.
• Power Supply Arrangements — sources, auxiliary transformers, changeover systems, load distribution, and maintenance responsibilities.
• Load Calculations — accurate methods to calculate DC, AC, and IPS loads for various signalling installations.
• Protection Systems — earthing, lightning and surge protection, transient suppression, and safe bonding practices.
• Solar Applications — harnessing renewable energy for signalling power requirements.
• Testing & Commissioning Procedures — including pre-commissioning checklists, performance monitoring, and preventive maintenance routines.

By the end of this course, you will be equipped with the knowledge to:

• Understand the complete power architecture for signalling installations.
• Select, operate, and maintain power equipment as per railway standards.
• Identify and resolve common faults to ensure uninterrupted signalling operation.
• Apply best practices for safety, efficiency, and long-term reliability.

Whether you are a railway signalling engineer, maintenance supervisor, trainee technician, or an enthusiast seeking deep technical insight, this course provides a solid foundation and practical skills for managing railway power supply systems.
