The railway industry is moving toward more sustainable, electrified, and highly configurable models. Each new project involves thousands of technical and regulatory requirements that must be managed with precision, where complexity no longer lies only in the train itself, but in how its development is coordinated in a controlled and profitable way.
Trains
Advanced digitalization for train and rolling stock suppliers
Railway OEM suppliers must adapt to multiple customers, standards, and digital environments without losing competitiveness. Design reuse, configuration control, and full traceability enable a more agile response to new contracts and reduce risks at every stage of the project.
Main challenges in the railway industry
Each railway project involves multiple configurations, variants, and specific requirements by customer and country. Manual change management generates errors, rework, and contractual risks.
A single digital structure enables version control, baseline definition, and full traceability from requirements through manufacturing.
Railway contracts are awarded under strict criteria of quality, cost, maintenance, and energy efficiency throughout the entire lifecycle.
Intelligent reuse of designs, templates, and accumulated knowledge makes it possible to generate more competitive proposals in less time.
The disconnect between design and industrialization creates inconsistencies, manufacturing errors, and cost deviations.
Integration between mechanical engineering, electrical engineering, validation, and production processes enables virtual validation before manufacturing and reduces physical prototypes.
International regulations, railway standards, and functional safety requirements demand full traceability of design and validation decisions.
Model-based engineering and the virtual twin enable compliance validation from the earliest stages.
Emission reduction, energy efficiency, and structural optimization are priorities in new railway contracts.
Advanced simulation makes it possible to validate multiple design variables before manufacturing, reducing weight, materials, and energy consumption.
Benefits for railway OEM suppliers
Capture of previous projects, modular libraries, and configurable structures that enable faster new developments.
Faster and more accurate generation of technical proposals for RFQs, increasing the award rate.
Integrated management of requirements, design, changes, and validation within a single source of information.
Virtual validation through structural simulation, dynamic analysis, and digital testing.
Secure and controlled access to product information, facilitating integration into collaborative environments required by major manufacturers.
