You'll design, analyze, integrate, test, and validate the critical thermal architectures that bring modern passenger trains to life-from HVAC systems and cab climate controls to traction cooling loops, battery thermal management systems, heat exchangers, and fluid dynamics models. Serving as both the thermal engineering subject matter expert and thermal system owner, you'll ensure optimal thermal performance, passenger comfort, equipment cooling, regulatory compliance, reliability, maintainability, and customer requirements are achieved throughout the project lifecycle.
