Rolling Stock Technologies

Electrical Power Generation

Rolling stock, such as locomotives and electric rail cars, uses high-voltage power systems to power traction motors and auxiliary systems. Systems like ABB’s traction converters allow for flexible voltage settings and improved energy efficiency, adapting to various grid requirements and reducing energy loss during power transfer. Additionally, these systems are designed to integrate seamlessly with Train Control and Management Systems (TCMS), ensuring real-time monitoring and optimization of power usage​.

Electrical Power Distribution

Power converters in rolling stock are essential for maintaining the integrity and reliability of the onboard power supply. Modern rail applications require ruggedized DC-DC converters to withstand harsh conditions and deliver stable power for onboard electronics, passenger amenities, and train control systems. EN 50155 standards guide the design to ensure safety, environmental resilience, and compliance with strict electromagnetic compatibility (EMC) standards.

Traction Power, Regenerative Power and DC Link Protections

Traction power and regenerative braking systems in rolling stock are integral for efficient energy use. Traction systems provide the necessary power to propel trains, while regenerative braking captures kinetic energy during deceleration, converting it into electrical energy that can be reused or returned to the power grid, which reduces overall energy consumption. These systems are often equipped with advanced power management features to optimize energy flow and maintain performance.

To protect DC link systems, which connect various high-voltage components, specialized protections are implemented to handle voltage fluctuations and surges that could arise from switching events or faults. These protections help maintain operational stability by preventing damage to critical electrical parts, contributing to a safer and more reliable rail system.

Train Control and Intelligence

Advanced Train Control and Management Systems (TCMS) enable centralized monitoring and control, improving operational efficiency and safety. TCMS is integrated with traction systems to optimize performance and diagnostics, helping operators manage scheduling, maintenance, and energy use more effectively. These control systems play a significant role in predictive maintenance, allowing operators to detect and address issues before they lead to failures, enhancing train reliability and safety.
