Train to Ground

Resilient, secure broadband communications for urban and metro rail

Nokia Train to Ground is a proven, secure and highly resilient broadband solution for urban and metro rail communications. Based on a unique intelligent multipath connectivity switching algorithm developed by Nokia Bell Labs, it delivers high reliability and performance that enable urban/metro rail operators to simultaneously support:

  • Safety-critical applications such as Communications Based Train Control (CBTC) and SCADA
  • Safety-related applications such as real time CCTV streaming, mission-critical voice, door clearance and passenger information systems (PIS)
  • Non-safety-related applications such as public Wi-Fi and infotainment

Train to Ground provides the extreme resilience, assured throughput, advanced security and guaranteed quality of service (QoS) that your urban/metro rail operations demand. The solution is highly flexible and supports both LTE and Wi-Fi access backhaul.

Our professional services experts can quickly deploy and integrate the Train to Ground solution into your existing operational technology (OT) environment using fully digitalized service delivery powered by our digital network architecture.

With Nokia Train to Ground, you get a robust mission-critical broadband connectivity foundation that lets you use the latest railway applications to make your operations faster, safer and more efficient.

Mission-critical performance with intelligent multipath connectivity switching

Train to Ground brings mission-critical performance to urban/metro rail communications with a switching algorithm that enables capacity aggregation over multipath multi-technology concurrent access backhaul to boost throughput and ensure resiliency.

A solution proven in urban/metro rail networks across the globe

Train to Ground has been commercially deployed in more than 11 urban/metro rail networks, including Paris Metro Lines 4, 11 and 14, Sao Paulo Metro Line 4 and Austria’s Westbahn. It is backhaul agnostic and works with Wi-Fi, LTE or a hybrid access infrastructure.
