Enabling Precise, Automated Train Control
At the heart of this deployment is Medha’s Communications-Based Train Control (CBTC) solution. This advanced system is engineered to enable the safe and efficient operation of trains in busy metro environments using sophisticated automation and continuous communication.
For passengers, the benefits are tangible. The CBTC solution, powered by QNX, helps to:
- Coordinate train movements
- Optimize headways (the time between trains)
- Reduce delays
Ultimately, this enhances operational performance and improves the overall passenger experience.
Meeting the Highest Standards for Safety
To operate in a modern rail environment, this system must meet the industry’s most rigorous safety demands. Medha’s CBTC solution is engineered to meet EN50128 SIL 4 certification, which is the highest safety integrity level for railway signaling applications
To achieve this, the system is powered by the QNX® OS for Safety. The OS is pre-certified to IEC 61508 SIL3, an integration that allows for compliance with stringent international safety standards. It delivers the proven reliability and fault tolerance that are absolutely essential for modern rail infrastructure.
Arunachalam Agastian, General Manager - Signalling at Medha Servo Drives, said the collaboration with QNX marks a significant step forward in modernizing India’s transit infrastructure, and that QNX’s proven software foundation is helping to set new standards for automation and control in urban rail. This deployment will deliver a smarter, safer, and more efficient travel experience for millions of daily commuters. QNX is proud to support Medha in delivering a next-generation CBTC solution for India’s rapidly evolving urban transit landscape.
A Trusted Foundation for Global Rail Systems
QNX OS for Safety is already deployed in critical rail systems around the world. It serves as the foundational platform for sTraffic’s unmanned train control system in South Korea’s KORAIL Metro. In Portugal’s national rail network, Critical Software selected QNX to support a safety-critical railway protection system. These global implementations underscore QNX’s reputation as a trusted provider of high-assurance software for rail transportation infrastructure.
QNX is committed to providing the trusted foundation for the software-defined businesses of the future. Its technology is trusted across industries, including automotive, medical devices, industrial controls, rail, and aerospace and defense.
