Challenge
A major European train OEM needed to implement the European Rail Traffic Management System (ERTMS), the standard for Automatic Train Protection. The system required continuous supervision of train movements through a complex information exchange with trackside subsystems while ensuring fail-safe operations for emergency braking and speed control. The project demanded zero-defect software development, meeting the highest safety standards.
Solution
Quest Global implemented a bespoke ERTMS solution that:
Assembled expert teams meeting stringent SIL-4 requirements according to CENELEC standards
Developed and tested critical onboard components, including Kernel Module and Driver Machine Interface
Implemented validation for trackside elements, including Radio Block Center
Optimized GSM-R protocol implementation for reliable communication
Established automated testing frameworks for continuous quality assurance
Results – At A Glance
Reduced test execution time by 80% through automation and DevOps
Delivered zero-defect software, meeting all safety requirements
Achieved full ERTMS standards compliance
