Applications
New-Build
AC 3-Tier
Designed for evaluation subject to OEM/operator requirements, with emphasis on thermal stability and condensate-based water recovery across long overnight journeys.

Representative engineering visual — indicative LHB-type rake. Not an OEM-approved livery or configuration.
System Architecture
- AQUA-R condensate recovery sized for extended duty cycles
- THERM-R thermal stability monitoring overnight
- CORE-ERMC diagnostics
Installation Approach
New-build integration or retrofit, subject to coach configuration and operator programme.
Interfaces
- Existing RMPU architecture
- Coach water and drainage systems
Engineering Considerations
- Extended unattended operating windows
- Water storage and drainage routing within the underframe
Expected Validation Process
Bench and single-coach validation across a full overnight duty cycle before wider consideration.
TransO2 system configurations, performance characteristics and component arrangements shown on this website represent engineering concepts, development targets or illustrative architectures unless expressly identified as validated or measured. Final system configuration is subject to detailed engineering, rolling-stock survey, testing, safety assessment, certification and operator/OEM requirements.
