Tunnel Safety Simulator

An immersive 3D safety planning tool transforming how rail teams prepare for tunnel operations.

Case Study

Enhancing Railway Safety Through Virtual Tunnel Planning

For KiwiRail, we developed a Tunnel Safety Simulator designed to enhance worksite planning and safety for rail works within tunnels across New Zealand. This tool allows workers to place 3D props into detailed tunnel replicas, creating safety scenarios that help teams visualise and discuss site setup, identify potential risks, and discuss hazard management in various situations.

We created an advanced environmental simulation system.
Using Unreal Engine 5.3, we recreated every railway tunnel in New Zealand’s network—over 140 in total. The simulator features a comprehensive library of 100+ props, precise measuring tools, and advanced environmental systems that model how wind affects equipment fumes and smoke within tunnels. This powerful combination of features brings unprecedented levels of safety planning and preparation to KiwiRail’s operations.
We created a new standard in safety planning.

The Tunnel Safety Planner has been a resounding success for KiwiRail, with work crews now using it daily as a core part of their site preparation. The interactive 3D environment allows crews to envision themselves in the physical space, sparking lively discussions and enabling real-time experimentation with different layout options. This immersive approach not only fosters greater engagement but also improves familiarity with the worksite, significantly enhancing awareness of safety hazards before teams even set foot on site. The ability to quickly iterate and adjust health and safety plans has streamlined what would traditionally be a slow and unengaging process, making it more accessible and collaborative.

The project’s impact has been recognised with a finalist position in the 2024 New Zealand Safeguard Awards for workplace safety innovation.

Key Features

Customisable safety scenarios with a library of 100+ 3D props available for planning and risk assessment.
An environmental system that simulates wind effects on fumes and smoke, providing realistic hazard visualisation.
Client Experience

“Working with Prismatic Studios was an incredibly smooth and rewarding experience. They demonstrated an exceptional ability to understand KiwiRail’s unique safety and operational needs, translating these into an elegant and immersive solution. The team quickly grasped the critical aspects of our project, enabling them to create a ‘Tunnel Simulator’ that is both highly engaging and user-friendly. This simulator has transformed our approach to safety planning, allowing our crews to visualise and interact with complex work environments before even stepping foot on site. Prismatic Studios has made it easy for our teams to engage with the simulation, enhancing both their planning effectiveness and their confidence in executing high-risk tasks. We look forward to continuing our partnership with Prismatic Studios to push the boundaries of safety and training.”
