ENGINEERED FORABSOLUTE SAFETY.
TransO2™ is an Environmental Operating System for railway rolling stock — integrating air, thermal, energy, safety, water and digital intelligence into one modular architecture.
Seven modules. One railway-qualified architecture.
TransO2 integrates air, thermal, energy, safety, water and digital intelligence into a single modular system — engineered as a platform, not a single product.
One coach. Multiple resource flows.

Illustrative system behaviour. Actual pathway and performance are subject to detailed engineering and validation.
Designed as a system. Engineered as a railway.
Engineering-Led
TransO2 is a systems-engineering platform, not a single product. Every claim starts from architecture, not marketing.
Deterministic Safety
AI augments engineering — it never replaces it. The safety barrier is always deterministic control logic.
Validated, Not Claimed
Every number carries a label: concept, simulation, target, or measured. We do not blur the line.
Retrofit and New Build
Designed for progressive integration into existing fleets, and ready for the next generation of rolling stock.
Engineered for existing fleets
TransO2-LHB Retrofit™ is designed for progressive integration into existing rolling stock, enabling railway operators to introduce environmental intelligence, diagnostics, safety monitoring and resource optimisation — without requiring an immediate replacement of the complete HVAC architecture.
Ready for the next generation of rolling stock
Designed for evaluation and integration subject to OEM/operator requirements.
From coach intelligence to fleet intelligence
CORE-ERMC fuses sensor, edge and subsystem data into a live train digital twin — coach-by-coach status for air quality, thermal, energy, safety, water and equipment health, feeding a depot / fleet platform.
