Rail-Grade Materials & Construction
Fire safety is non-negotiable in rail. Every material in our railway cable assemblies is selected for low smoke, zero halogen performance, and resistance to the vibration, temperature extremes, and chemical exposure that rail environments demand. From the wire insulation to the outer jacket, every component meets or exceeds EN 45545-2 requirements.
LSZH (Low Smoke Zero Halogen) Jacketing
EN 45545-2 compliant materials that produce minimal smoke and no toxic halogen gases in a fire event — critical for passenger safety in enclosed carriages and tunnels
Cross-Linked Polyolefin Insulation
XLPE insulation rated -40°C to +125°C, resistant to oils, fuels, and hydraulic fluids found in rolling stock environments
Tinned Copper Conductors
Corrosion-resistant conductors that maintain reliable crimped connections under constant vibration and thermal cycling
Stainless Steel Braided Protection
Mechanical protection for cable assemblies routed under bogies or through exposed areas subject to ballast impact and debris
Rail-Rated Connectors
Amphenol, TE Deutsch, Harting Han, and M12 circular connectors qualified for railway vibration profiles and IP67+ sealing

Frequently Asked Questions
Common questions about rail & transport cable assembly solutions
Do your cable assemblies meet EN 45545-2 fire safety requirements for rail?
Yes, we manufacture cable assemblies using halogen-free, low-smoke zero-halogen (LSZH) materials that meet EN 45545-2 fire safety requirements for railway rolling stock. We select wire insulation, jacketing, and heat shrink materials rated to the appropriate Hazard Level (HL1, HL2, or HL3) based on your vehicle classification and installation location. All materials are third-party certified with test reports for smoke density, toxicity, and flame propagation.
Can you supply cable assemblies for Australian rail signalling systems?
Absolutely. We produce cable assemblies for trackside signalling cabinets, interlocking systems, point machines, axle counters, and wayside equipment. These assemblies are built with shielded cables for EMI protection, IP67 sealed connectors for outdoor enclosures, and UV-resistant jacketing for exposed installations. We support both legacy relay-based signalling and modern ETCS/CBTC digital signalling systems used on projects like Sydney Metro and Melbourne Metro Tunnel.
What connectors do you use for rail applications?
We work with all major railway connector families including Amphenol Rail, TE Connectivity Deutsch DT/DTP/DTM series, Harting Han industrial connectors, M12/M8 circular connectors for sensors and Ethernet, and MIL-DTL-38999 for high-reliability applications. Connector selection depends on the vibration profile, IP rating, and current/voltage requirements of each application.
What is your experience with Australian rail projects?
We supply cable assemblies for rail projects across Australia, supporting rolling stock manufacturers, signalling contractors, and infrastructure operators. Our Melbourne-based engineering team understands Australian rail standards including AS 7657 (rolling stock wiring), AS/NZS 3000, and state-specific requirements for metro, regional, and freight rail applications.
Do you offer prototyping for rail cable assemblies?
Yes, we offer rapid prototyping with 1-2 week turnaround for rail cable assemblies. This includes first article samples with full documentation, allowing you to validate fit, form, and function before committing to production quantities. We support design iterations and can scale from prototype to volume production of thousands of harnesses per month.
Can your cable assemblies withstand the vibration levels in rail applications?
Yes. Rail vehicles experience continuous vibration from track irregularities, traction systems, and braking events. Our cable assemblies are designed with strain relief, abrasion protection, and vibration-resistant terminations. We use crimped connections (not soldered) for reliability under vibration per EN 61373 shock and vibration categories, and all assemblies are secured with appropriate clamping and routing to prevent chafing.
