We can help with
Electrical Engineering
Our Electrical Engineering division delivers complete end-to-end solutions for rolling stock from schematic design and control systems integration to lighting, automation, and validation testing. We ensure every electrical system is optimized for reliability, efficiency, and compliance, supporting safe and seamless rail operations across passenger and freight fleets.
Our methods
CRWS can help with
- Electrical Schematics: Designing precise and compliant schematics that map out complete electrical systems for rolling stock, while also updating legacy diagrams to reflect undocumented modifications and field changes – ensuring accuracy, traceability, and integrations with system controls.
- Electrical Panels: Designing and integrating robust electrical panels for control and power distribution, using railway-approved components and the latest technologies to ensure reliability, safety, and long-term performance in demanding railway environments.
- Distribution sizing: Calculating and optimizing electrical load distribution to ensure safe, efficient, and scalable power delivery across all onboard systems and to the entire train fleet.
- Integrated System Design & Controls: Designing and engineering control systems for a wide range of onboard functions – including propulsion, braking, HVAC, lighting, door systems, convenience outlets, and kitchen equipment – ensuring seamless integration, operational reliability, and enhanced passenger experience through intelligent automation.
- Wiring and conduits: Designing and installing efficient wiring and conduit systems that support a wide range of onboard functions. This includes planning optimal routing for accessibility and space management, selecting appropriate wire sizes based on load and environmental conditions, and ensuring full compliance with railway standards.
- Troubleshooting of electrical systems: Identifying and resolving issues across a wide range of onboard electrical systems – including doors, HVAC, lighting, and auxiliary equipment – by analyzing faults, tracing wiring, and verifying component functionality to restore safe and reliable operation.
- Lighting: Designing lighting systems that enhance passenger comfort and create ambient effects while ensuring adequate illumination for safety and emergency situations. Simulations are performed to validate lighting levels and confirm compliance with industry standards.
- Emergency Systems: Designing and evaluating emergency systems such as backup power, fire detection, and evacuation lighting to ensure passenger safety and operational readiness. Battery scenarios are developed to determine appropriate sizing of emergency batteries for powering critical equipment – including lighting and communication systems – in accordance with established industry standards.
- Locomotives: Designing key locomotive systems including genset, propulsion control, CCTV systems, and operator control desks. Solutions are tailored to meet performance, safety, and ergonomic requirements, ensuring seamless integration with onboard systems.
- Testing & Validation: Preparing and executing a wide range of tests to ensure proper functionality and compliance of onboard systems. Testing activities include battery sizing validation, HVAC performance checks, megger and continuity tests, electrical panel functionality assessments, and more – each performed to confirm system reliability and alignment with industry standards.
- Automation: Integrating smart automation technologies for monitoring, diagnostics, and control, enabling predictive maintenance and streamlined operations.
