US firm Green Hills Software will supply its Platform for Industrial Safety software for Canadian firm Bombardier's next-generation train control management system.
The platform will include the IEC 61508 SIL3 safety-certified INTEGRITY real-time operating system and the MULTI integrated development environment.
Green Hills said the software is able to handle multiple levels of information through a single processor, meaning any faults will not have an adverse effect on the rest of the system.
The company will also develop and conduct the CENELEC EN 50128 safety certification, the European standard for railway communications, signalling and processing systems, for Bombardier's system.
Bombardier's new train control system is being designed to be more flexible and easier to upgrade than its existing systems.
