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.
