Railway & Rolling Stock
Safety-Critical Software for Modern Rail.
Certified toolchains for onboard controllers, signalling systems, and rolling stock software, with EN 50128/50716 compliance support for India's expanding rail modernization programme.
India’s railway sector is undergoing a historic transformation, from Vande Bharat production scaling to ETCS Level 2 signalling rollout and KAVACH indigenous ATP deployment. Every onboard controller, braking system, and train management unit runs safety-critical embedded software that must meet EN 50128 (software) and EN 50716 (development tooling) certification requirements. GSAS provides the complete development, testing, and compliance toolchain for rail embedded teams.
Static analysis with Klocwork and Helix QAC enforces MISRA C:2023 and railway-specific coding standards, providing the code quality evidence required for SIL certification. SEGGER J-Link PRO and J-Trace provide real-time debug and trace across Arm Cortex-R and Cortex-M targets used in train control units, door controllers, and traction inverters.
For signalling and interlocking software, where the highest safety integrity levels apply, GSAS supports the full EN 50128 V-model lifecycle, from requirements traceability through verified object code, with tool qualification documentation that satisfies independent safety assessors. Our engineers have hands-on experience with railway-specific compliance gaps and can accelerate your path from prototype to SIL 4 certification.
