Railroad Signaling, R&D, and Consulting

A Jacksonville, Florida engineering firm. Creators of RWTS™ — the open IoT standard that unifies wayside equipment data — and the Wayside Maintenance Monitoring System that implements it.

Make every wayside device speak the same language.

Every manufacturer speaks its own protocol, so a multi-vendor wayside means custom translation at every seam and back-office systems built around one supplier's equipment. The Railroad Wayside Telemetry Standard™ (RWTS) replaces that with one open contract for grade crossings, signals, switches, detectors, and power systems.

100+ equipment families

One vocabulary for crossings, signals, switches, detectors, power systems, and more.

800+ standard alarm codes

The same alarm means the same thing from every vendor, in one message format over MQTT or SNMPv3.

Open by design

Creative Commons licensed. Free to implement in any product, including proprietary firmware. No fees, no vendor lock-in.

Your hardware. Our software.

WMMS™, the Wayside Maintenance Monitoring System, is the reference implementation of RWTS™. It adds a non-vital, read-only monitoring layer to the equipment you already operate.

Wayside Maintenance Monitoring System architecture Wayside Sentinel runs at each wayside location and polls local equipment — grade crossings, signals, switches, detectors and power systems — read-only. It has two parallel outputs over MQTT or SNMP. The first carries RWTS in its compact wire format to two optional central components, Wayside Overwatch, the dispatch-side fleet dashboard, and Wayside Nexus, long-term time-series storage. The second carries RWTS Expanded, the same messages with human-readable keys, to existing SCADA systems, historians and dashboards that do not implement the protocol.

Sentinel is the only required component. Overwatch and Nexus are optional and attach to an existing Sentinel fleet. In parallel, Sentinel emits RWTS Expanded, the human-readable form of the same messages, so existing MQTT and SNMP consumers ingest wayside data without implementing the protocol. Polling of wayside equipment is read-only throughout — the platform observes and reports, it never commands.

Wayside Sentinel

Edge monitoring. Connects existing wayside equipment, normalizes the data, and operates locally.

Railroad Expertise

Our principal engineer brings more than 16 years designing signal systems for Class I railroads, regional carriers, and short lines across North America, including work through earlier employers on CSX, BNSF, Union Pacific, and Canadian National projects. We built RWTS because we lived the interoperability problem firsthand.
