A seemingly minor winter track delay, such as a failed joint in the Midwest, can escalate into hours of freight disruption, rerouting, and elevated costs. These incidents underscore the operational importance of rail joint integrity.
At One Rail Group, we specialize in Electric Flash-Butt (EFB) Welding. This precision-controlled process eliminates mechanical joints and defects by forging rail ends under high-current electrical resistance. This method forms seamless rail that improves ride quality, reduces maintenance cycles, and extends track life.
Continuous Welds, Stronger Networks
Bolted joints are long-standing failure points in rail infrastructure. Subject to vibration, fatigue, and temperature variations, these joints loosen over time, leading to noise, increased wear, and the need for safety inspections. EFB welding addresses these issues by producing continuous welded rail (CWR) with high-strength bonds resistant to thermal expansion and stress.
By converting jointed rail through Cut & Slide or replacing defects via Rail Insert® Welding, railroads gain smoother logistics, reduced lifecycle costs, and enhanced service reliability. EFB welding is particularly critical in high-tonnage and high-speed corridors where consistent rail geometry is essential.
Mobile Precision, Minimal Disruption
One Rail Group’s mobile EFB welding units deliver on-site joint elimination and defect removal with high repeatability. Each unit includes hydraulic rail pullers, automated alignment via Auto-Crowning, and real-time weld monitoring, ensuring quality at every closure.
The EFB process clamps, aligns, heats, and forges rail ends with precision. Welds are ground to profile and restored to the preferred stress state, enabling faster line reactivation with minimal service impact.
Whether for planned upgrades or emergency response, our AREMA-compliant mobile welding fleet helps clients meet today’s infrastructure demands with precision and speed.
