Our services include

Railway Clearance Assessment

Route, structure, platform, passing, and vehicle-to-vehicle clearance assessments, supported by specialist engineering interpretation.

Dynamic Vehicle Modeling

Creation and refinement of vehicle models, swept envelopes, movement tables, suspension behavior, and vehicle overthrow.

LiDAR and Survey Data Processing

Conversion, collection, management and processing of point-cloud and survey data into track-referenced structure profiles and clearance assessment files

Probabilistic Gauging

Traditional absolute gauging applies defined allowances to create a conservative assessment. Probabilistic gauging uses Monte Carlo statistical distributions to represent the variability of selected parameters. Reduced conservatism can save considerable costs when considering modification of vehicles and infrastructure.

Clearance and Route Feasibility Software

Clearance software can help organizations complete routine assessments, compare design options, manage data, and produce consistent reports. Software can be used as part of an internal engineering capability or alongside specialist consultancy support.

Training and Technical Support

Clearance results are often used by people who are not specialist gauging engineers.Project managers, designers, surveyors, rolling stock engineers, and asset managers all benefit from understanding the assumptions behind the assessment.

Why work with D/Gauge and TÜV Rheinland?

Document with a Checklist

  • Railway Engineering

    Everything starts with experienced clearance engineers. Our engineers have written, contributed and advised on gauging standards across the globe.

  • Technology and Digital Infrastructure

    Purpose-built software developed specifically for railway engineering. Trusted engineering data supports faster and more accurate decisions.

  • Independent Advice

    Objective assessments supporting operators, manufacturers, consultants, and infrastructure managers.

  • One Service Environment

    Clients can commission a complete specialist assessment, build an internal self-service capability or combine both approaches. Routine work can be completed through software, while complex or unusual cases can be escalated to experienced clearance engineers.

  • Clear Technical Outputs

    Gauging results must be understood by more than the engineer running the calculation. We structure reports and visual outputs so designers, project managers, assurance teams and asset owners can understand the issue, its cause and the available engineering options.

  • The Right Assessment for the Right Problem

    Not every clearance challenge requires the same methodology. Many providers rely on a single assessment technique, typically kinematic analysis. DGauge's expertise spans static, kinematic, comparative, full dynamic, absolute and probabilistic clearance assessment, enabling us to select the most appropriate engineering approach for every project.
