Clearance and Gauging Services for Railway Technology

We assess the space between railway vehicles and infrastructure using advanced simulation and gauging techniques. This ensures trains can operate safely and efficiently within the physical constraints of a route. Our process includes modelling the vehicle movement, infrastructure geometry, and track alignment to identify potential conflicts or non-compliances.

We use our own internally developed software called PhX and D/Gauge Rift. Both software have been operating for decades providing exceptional clearance capabilities. TÜV Rheinland’s calculations are completed using industry-leading clearance analysis software. It delivers fast, detailed results through advanced simulation, a structure library, and configurable safety margins to suit international standards and project needs.

Yes, we can work with your existing infrastructure and vehicle data. If that’s not available, we can source or collect network data using trusted survey partners and open data sources, ensuring your project has the right foundation for accurate clearance analysis.

Gauging is the process of measuring whether trains can safely pass through infrastructure, such as tunnels, platforms, and bridges, without striking anything. Clearance refers to the actual space or distance between the train and surrounding structures. Simply put: gauging is the assessment; clearance is the result. Together, they ensure safe and efficient rail operations.

Yes. Intelligent gauging unlocks the ability to run more services, introduce new rolling stock, or optimise existing routes—all of which can increase passenger or freight capacity. By identifying underused clearance, you can safely make better use of your infrastructure and drive higher returns from your assets.

Absolutely. Gauging data helps you avoid unnecessary infrastructure modifications, reduce service disruptions, and make informed investment decisions. It supports efficient planning, risk mitigation, and smarter route design—leading to long-term cost savings and more profitable operations.
