The Conductor Systems
Rail Runs On.
CDG designs and manufactures the electrical conductor components — traction motor leads, gladhands, quick-disconnect connectors, and custom cable assemblies — that keep every electrified and diesel-electric fleet moving across North America.
Between power and performance.
Conductor Dynamics Group manufactures the electrical conductor systems that every diesel-electric and fully electric rail vehicle requires to move. These components are not optional, not commoditized, and not easily replaced — they are specified at the OEM level and replaced on predictable maintenance cycles.
Every component is engineered to OEM specification, manufactured in-house at our Cookeville, TN facility, and built to survive the heat, vibration, and contamination that take other parts out of service.
Built for the duty cycle of real rail.
Three primary product lines, engineered from the ground up for the environments, specifications, and maintenance cycles of North American rail operations.
Traction Motor Leads
Direct-fit replacement leads for GE, EMD, and Siemens traction platforms, manufactured to original tolerances and insulation specifications. Built for the thermal cycling and vibration of continuous road service.
Gladhands & Quick Disconnects
Handshake and jack-knife style connectors for fast, secure connect/disconnect in shop and field environments. Rated for the high-current, high-cycle demands of transit maintenance operations.
Cable & Harness Assemblies
Custom-terminated cable assemblies and wiring harnesses built and tested to your print or sample. From a single prototype to full production runs, with full documentation for fleet qualification.
Built for three demanding worlds.
From urban subway systems running 20-hour days to Class I freight locomotives hauling through extreme weather — our conductor systems are in service across the full North American rail spectrum.
Rapid Transit
High-cycle connectors and conductor assemblies built for the relentless start-stop duty of metro, subway, and light-rail systems — where uptime is measured in seconds of headway.
Freight Rail
Heavy-duty traction motor leads and gladhands engineered to endure the heat, vibration, and contamination of Class I and short-line road service across North American corridors.
Passenger Rail
Reliable, low-maintenance conductor systems that keep intercity, commuter, and high-speed fleets in revenue service — with the documentation and traceability that fleet operators require.
From a single connector to a complete harness.
A full line of conductor products, plus the engineering capacity to build custom assemblies from a drawing, a sample, or a specification.
Traction Motor Leads
Direct-fit replacement leads for GE, EMD, and Siemens platforms, manufactured to original tolerances.
Gladhands & Quick Disconnects
Handshake and jack-knife style connectors for fast, secure connect/disconnect in shop and field.
Cable & Harness Assemblies
Custom-terminated cable assemblies and wiring harnesses built and tested to your print.
Conductor Engineering
Reverse-engineering and design support to develop conductor systems where no drawing exists.
Contact & Connector Systems
Precision-machined contacts and connector bodies for high-current rail applications.
Aftermarket & Replacement
In-stock and made-to-order replacement components to minimize fleet downtime.
Built here. Built to endure.
Domestic manufacturing means resilient lead times, tighter quality control, and components you can trust in the field — order after order. Every product leaves our facility with full documentation and traceability.
The standard our customers count on.
OEM Quality
Direct-fit replacements engineered to match the original part, dimension for dimension, insulation spec for spec.
Precision Manufacturing
Machined and assembled in-house to exacting tolerances, with documented quality control at every stage of production.
Custom Engineering
From a print, a sample, or a conversation — we build what isn’t on the shelf, and we do it fast.
Domestic Supply
U.S. manufacturing keeps lead times short, quality consistent, and compliance with Buy-American provisions guaranteed.
