Locomotive Onboard Data Gateway
The onboard data gateway aggregates vehicle data and provides a common time reference across the onboard system. Its redundant industrial platform is designed for locomotive power, vibration, and electromagnetic conditions. It can collect locomotive-control, event-recorder, and other vehicle-interface messages, then supply structured data such as speed and location to the onboard computer for correlation with video-gateway streams. It also supports train-to-ground data exchange.
Core capabilities
Multi-Protocol Vehicle-Data Aggregation
Collects vehicle messages through CAN, RS485, and Ethernet, providing structured speed, location, and operating data to the onboard computer.
Common System Timing
Keeps track-ahead imagery, running-gear event images, and vehicle operating data aligned to a common time reference.
Encrypted Dual-Link Communications
Dual wireless modules provide primary and backup links for secure upload of alarms and high-resolution snapshots, and for receiving ground-side instructions.
Time-Correlated Offline Cache
Retains event imagery with its corresponding operating data through tunnels and other coverage gaps, then synchronizes records in batches after reconnection.
Remote Device Health Monitoring
Monitors connected cameras and interfaces for availability, helping maintain continuous data sources for the onboard computer.
Secure Data Exchange
Encrypts structured operating data, alarms and high-resolution snapshots, with logs to support secure train-to-ground data exchange.

Frequently Asked Questions
Can the onboard computer correlate video and vehicle data without the onboard data gateway?
It can still analyze video content, but without the gateway's common timing, speed, and location data, events cannot be fully correlated to vehicle context and reports have reduced traceability.
How are event records retained through communications gaps?
When configured with local storage, the video gateway can retain video and event imagery while the data gateway retains the corresponding time, speed, location, and operating records. The system can synchronize those records on a shared timebase after reconnection.
What role does the onboard data gateway play in track-ahead and running-gear monitoring?
It gives the onboard computer a common time reference together with structured speed and location data. The computer correlates this with track-ahead and running-gear streams from the video gateway, while the data gateway can also manage secure train-to-ground transfer.
