Consulting and support across railway diagnostics

What we do

Our role in this domain is that of an engineering partner. We do not lay tracks and we do not own measurement carriers – we make sure that what those carriers measure is correct, meaningful, and usable. The work is typically advisory and development-oriented: documentation, methodologies, data analysis, system integration, and, where it makes sense, on-site methodological supervision alongside contractors.

We work with several types of partners. We help contractors who run diagnostics under their contracts prepare procedures, reports, and result analysis. We provide diagnostic equipment vendors with independent expertise and help them adapt their offering to local requirements. We prepare documentation for infrastructure operators and engineering studios for tender packages, planning of measurement campaigns, and acceptance commissions.

Subsystems we cover

• Track geometry measurement. Gauge, cant, rail twist, vertical and horizontal alignment, dynamic track characteristics.
• Rail flaw detection (NDT). Detection of internal and surface defects in rails and welds – ultrasonic, eddy-current, and magnetic methods, analysis of findings, and planning of repeat measurements.
• Catenary (overhead contact line). Contact wire geometry, height and stagger, pantograph contact force, electrical parameters, and interaction with rolling stock.
• Structure gauge and clearances. The space between trains and surrounding structures, structure gauge testing, recording of deviations, alignment with the prescribed clearance envelope.
• Video inspection of the track superstructure. Imaging of rails, fastenings, sleepers, and ballast; automatic defect detection and feature measurement from the video feed.
• Adjacent domains. Signalling and safety systems, telecommunications, underground installations – on demand and together with specialised partners.

How we engage

Technical documentation

Test programs, measurement methodologies, equipment mounting layouts, operating instructions, and report templates. Documents are prepared for a specific object and scope, with references to the applicable regulations and the partner's internal rules.

Consulting on measurement technologies

Selection of measurement systems (lidar, optics, video, ultrasonic, accelerometers, inertial units, GNSS), operating parameters, combinations of several technologies in one campaign, and assessment of accuracy and coverage.

Data analysis and reporting

Processing of raw equipment output, validation, matching against design values, anomaly identification, and statistical summaries. Reports are prepared in the formats used by contractors, clients, or regulators.

System integration

Connecting measurement components into a single data flow, time and geo synchronization, transferring results into central databases and reporting tools, and linking with the partner's internal systems.

Methodological support in the field

Monitoring procedure compliance, resolving disputed cases, training contractor staff, and accompanying critical measurements.

Alignment with regulatory frameworks

Preparation of documentation and processing of results in line with the relevant frameworks – European Technical Specifications for Interoperability (TSI), EN standards, and local rules – where that is part of the task.

Experience and typical outcome

We have worked on reconstructed lines in the Balkans, including high-speed sections. Part of that work consisted of technical analyses for contractors: assessment of specific measurement systems, mounting layout design for track measurement carriers, and analysis of results with prepared conclusions. Another part involved full documentation packages for diagnostic campaigns. A third part was data engineering, bringing field equipment output into operational reports.

A typical engagement ends with one of the following:

• a finished documentation package the partner can use directly;
• a recommendation backed by data and ready for client presentation;
• a working data pipeline from measurement to report;
• a field campaign with methodological support and on-time delivery to the acceptance commission.

Who this is for

• Contractors and engineering companies running diagnostics as part of track construction, reconstruction, or operation.
• Diagnostic equipment vendors – as independent expertise, a partner for adapting solutions to local requirements, or support on evaluation projects.
• Infrastructure operators and managers planning measurement campaigns and acceptance tests.
• Engineering studios preparing technical documentation for tenders and acceptance commissions.
