EN 50128
Railway Software
EN 50128 governs software for railway control and protection systems. It defines software lifecycle expectations, SIL-dependent techniques, independence, verification, validation, and configuration control.
It normally sits inside the lifecycle and feeds the safety case. The higher the software , the more formal the process, evidence, and independence expectations become.
CSA supports software planning, lifecycle gap reviews, V&V evidence, assessment readiness, training, and staffing for rail software safety and assurance teams.
