Trax-ing the future: How Digital QA is transforming Rail Delivery

“We built Trax to solve the exact problems we faced on site — scattered QA, missed handovers, and endless duplication. It had to be practical, field-friendly, and built for rail” – Scott Walker

We’re excited to welcome Scott Walker, Co-founder of Railway Engineering Solutions (RES), to the latest episode of the Railway Transportation Systems podcast.

Scott shares the journey behind Trax, the digital platform built by rail engineers, for rail engineers — solving real-world challenges in QA, compliance, and handover processes on major infrastructure projects.

🎙 In this episode, we explore:
 ✅ How Trax helped enable the world’s first fully digital signalling commissioning
 ✅ The platform’s role in streamlining field data and eliminating duplication
 ✅ Upcoming innovations, including AI-powered workflows and digital config management
 ✅ Lessons from delivering high-profile projects like Metro Tunnel and Caulfield–Dandenong LXRP
 ✅ Scott’s advice for aspiring railtech entrepreneurs navigating delivery and disruption

Whether you're managing rail systems, testing & commissioning, or curious about digital transformation in transport — this is one conversation you don’t want to miss.
