EPU Engineering
Railroad Signaling, R&D, and Consulting
About the firm
EPU Engineering is a Jacksonville, Florida engineering practice focused on railroad signal engineering, wayside telemetry, and software development. It created RWTS (Railroad Wayside Telemetry Standard), an open Apache 2.0 protocol that unifies grade crossings, signals, switches, detectors, and power systems under a common IoT message format regardless of vendor. EPU's engineers have designed and maintained signal systems for Class I railroads, regional carriers, and short lines across North America, including historical work for CSX, BNSF, Norfolk Southern, Union Pacific, Canadian National, and CONRAIL. Its Wayside Maintenance Monitoring System - comprising Wayside Sentinel, Wayside Overwatch, and Wayside Nexus - is the reference implementation of RWTS, providing edge monitoring, fleet dashboards, and centralized telemetry aggregation.

Capabilities
Railroad Signal Engineering
Service websiteWayside signal system design for short lines, regional carriers, and Class I railroads, covering grade crossings, interlockings, centralized traffic control, PTC and ATCS infrastructure, and AREMA Part 24.2.1 compliance.
- Grade Crossings
- Interlockings and CTC
- Hardware Configuration
Controllers, relays, and circuit configuration for wayside signal equipment.
- System Integration
Connecting disparate wayside equipment and protocols across multi-vendor deployments.
- AREMA Part 24.2.1 Compliance
Documentation and standards alignment for AREMA C&S Manual Part 24.2.1 requirements.
RWTS Implementation
Service websiteDeployment and integration of the open Railroad Wayside Telemetry Standard for vendor-neutral wayside monitoring, including edge software, optional fleet dashboard, and centralized aggregation.
- Wayside Sentinel
Edge software deployed at wayside locations for equipment polling, alarm evaluation, local data storage, and RWTS-formatted telemetry output. Supports legacy SNMP, Modbus, and serial equipment.
- Wayside Overwatch
Dispatch-side dashboard that aggregates Sentinel telemetry and alarms across a fleet in one view.
- Wayside Nexus
Centralized metrics collection and long-term storage for fleet-wide telemetry, ready to feed predictive maintenance, trend analysis, and reporting workflows.
Research & Development
Service websitePrototyping, standards development, and solution engineering for railroad and adjacent industrial domains. RWTS originated as an R&D project addressing the wayside interoperability problem that no existing product solved.
Engineering Consulting
Service websiteCustom software, system integration, industrial IoT, and technical advisory for railroad and enterprise clients.
- Software Development
Web applications, APIs, integrations, data analytics pipelines, time-series dashboards, and technical architecture for scale, security, and maintainability.
- Enterprise Infrastructure
Self-hosted collaboration, document management, and secure server infrastructure for organizations requiring regulatory compliance, data sovereignty, or cloud-cost reduction.
