Signalling and Rolling Stock
Railway Systems Engineering
We deliver railway engineering solutions that help our clients ensure safety, reliability, and integration throughout the entire system lifecycle.
Railway Signalling
End-to-end solutions: requirements management, design, validation, commissioning, and certification.
At ALOR, we bring our knowledge and experience to the development and implementation of railway signalling systems, both on-board and trackside.
- Functional analysis and requirements review.
- Train-to-ground integration and compatibility between rolling stock and infrastructure.
- Compatibility testing and support during on-track commissioning.
- Documentation review and functional validation.
- RAMS support in accordance with EN 50126 throughout the development lifecycle.
- Software development in accordance with EN 50716.
We work with advanced systems such as CBTC, ERTMS/ETCS, electronic interlockings, ATO/ATP systems, and communication equipment, providing technical support to ensure safe design and integration.
Typical Applications
We participate as an engineering partner in different types of signalling projects, providing specialized technical support throughout the entire system lifecycle:
New railway lines and extensions to existing networks.
Modernization and migration of interlockings and signalling systems.
ERTMS and CBTC deployment or migration projects.
Integration of new rolling stock into lines already in service and equipped with signalling systems.
Testing and certification of trains and signalling systems prior to commercial service entry.
Compatibility analysis, operational validation, and support for certification processes.
Rolling Stock
