With TRS-G2, ErvoCom introduces a next-generation train radio for the secure migration from GSM-R to FRMCS. This innovative dual-mode solution is built on the latest FRMCS architecture, seamlessly connecting all system components via Ethernet. At its core is the new HMI COCO24 with advanced touchscreen technology and integrated train radio logic. The CCU24 central unit acts as the GSM-R gateway to the existing infrastructure, while a future FRMCS gateway connects directly to the Human Machine Interface (VAS). Its open architecture supports multi-vendor strategies, simplifies migration, lowers lifecycle costs, and provides operators with maximum flexibility, strong cybersecurity, and long-term investment protection. TRS-G2 paves the way for the digital future of railway communications.
