Product Description

KARM-NG was developed in partnership with SNCF Connect to strengthen TVM armament control on French high-speed lines.

Based on secured GNSS train localization, KARM-NG continuously verifies the appropriate TVM protection is active and provides the required armament-control information to the onboard signaling chain.

Built on U-TEST® real-time technology, it also provides self-test, data recording, and maintenance capabilities in a compact railway-qualified architecture.

Key Benefits

Continuous TVM armament verification beyond trackside transition points

Maintains armament control after an onboard reset or restart on the high-speed line - Ligne à Grande Vitesse (LGV)

GNSS-based localization provides an independent indication of train position

Developed with SNCF Connect and deployed on TGV trains in commercial service

Railway-qualified, maintainable platform for long-term operation

Application Areas

automated test solutions for the railway industry
Railway
