Maintenance Observation Platform

The Wayside Maintenance Monitoring System is a non-vital maintenance observation platform. It monitors equipment health and generates maintenance alerts — it does not interface with vital signal logic or control train movements.

Product Architecture

Core

Wayside Sentinel

Edge software for wayside locations. Deploy independently or as part of a larger system.

+
Optional

Wayside Overwatch

Dispatch-side dashboard. Aggregates Sentinel telemetry and alarms in one fleet view.

+
Optional

Wayside Nexus

Centralized data aggregation and long-term storage. Ready to feed analytics tools.

Standalone

Wayside Sentinel

Edge Software for Wayside Locations

Wayside Sentinel runs at wayside locations — polling equipment, evaluating alarm rules, storing data locally, and communicating using the RWTS standard. Works independently; connects to Overwatch and Nexus for centralized capabilities.

  • Continuous equipment polling with configurable alarm thresholds
  • Local data storage with configurable retention
  • Offline operation with store-and-forward during outages
  • Legacy protocol support — ingests SNMP, Modbus, and serial from existing equipment and delivers RWTS-formatted messages upstream
Complements Sentinel

Wayside Overwatch

Dispatch-Side Dashboard

Wayside Overwatch is the dispatch-side dashboard. It receives telemetry and alarms from Sentinel deployments and presents the fleet in one view.

Complements Sentinel

Wayside Nexus

Centralized Metrics Collection

Wayside Nexus aggregates telemetry from your entire Sentinel fleet and stores it long-term — the data foundation predictive maintenance, trend analysis, and historical reporting tools build on. Nexus collects and stores; you bring or integrate your analytics layer.

  • Fleet-wide aggregation with 365-day retention
  • Time-series storage — every metric, every device, queryable
  • Analytics-ready — designed to feed predictive maintenance, trend analysis, and reporting workflows
  • Data export — CSV, JSON, and API access for downstream tools

Deployment Sizing

Each deployment is tailored to the railroad's size and operational requirements.

Short Lines

Single edge device per location. Sentinel-only deployment.

Regional Railroads

Distributed edge with centralized Overwatch.

Class I Railroads

Full fleet with Nexus aggregation. Enterprise integration.
