Railway Onboard Computer
The onboard computer provides the system's local edge-compute capability. It receives standardized video streams from the onboard video gateway and locomotive operating data from the onboard data gateway, using their shared time reference to correlate both sources. Local analytics can identify track-ahead and running-gear events and create alert reports with supporting key frames.
Core capabilities
Local Multimodal Analytics
Correlates standardized video streams from the video gateway with operating data from the data gateway without relying on cloud connectivity.
Track-Ahead and Running-Gear Analysis
Analyzes track-ahead video and running-gear imagery to help identify obstructions, rockfall, and equipment conditions.
Persistent Local Models
Supports locally deployed, optimised models with automatic key-frame extraction and organised event archiving.
Prioritised Alerts
Presents high-risk line events and major undercarriage faults with priority on the cab display.
Offline Analysis and Caching
Continues analyzing locally during communications outages and stores event imagery and findings for later synchronization.
Remote Model Maintenance
Supports incremental model updates to improve performance for track-ahead hazards and running-gear conditions.

Frequently Asked Questions
Can the unit run local analytics using track-ahead and running-gear video?
The onboard computer can analyze standardized video streams from the onboard video gateway together with locomotive operating data from the onboard data gateway. Supported analytics depend on the selected model, vehicle integration, and validation plan.
How do the onboard computer and video gateway divide work?
The video gateway connects directly to the cameras and manages capture, encoding, pre-screening, and recording before outputting standardized streams. The onboard computer correlates those streams with vehicle data from the data gateway and produces local analytics and alerts.
What remains available during a communications outage?
The video gateway can continue local capture and recording while the onboard computer continues analyzing available streams with vehicle data from the data gateway. Local analytics and alerting can continue without cloud connectivity when included in the configured system.
