Canadian winters surely can slow things down. And they test the limits of light rail systems every single day. Ice buildup on overhead catenary lines can interrupt power flow, damage infrastructure, and bring service to a halt when riders need reliable transportation the most.This past winter, light rail systems across Canada experienced heavy icing, as thick as two inches on some wires! For transit authorities, the challenge is
That is where BLUE WIRE, the only automated catenary wire heating system comes in.
Unlike rail switches, catenary systems are exposed along miles of track—making them especially vulnerable to:
Even a thin layer of ice can disrupt current collection, leading to:
Traditional approaches—such as manual de-icing or chemical maintenance—are hazardous and inefficient. They are also often performed too late, after ice has already formed on wires.
Traditional catenary ice management relies heavily on manual intervention—crews physically removing ice through scraping or applying de-icing chemicals like glycol. These methods are labor-intensive and costly, while also accelerating wear on catenary lines, which shortens asset life through repeated mechanical stress. Chemical treatments introduce additional concerns, including environmental hazards and ongoing material costs.
By reducing reliance on field crews and avoiding damaging removal techniques, BLUE WIRE lowers operating expenses, extends infrastructure lifespan, and provides a safer, more sustainable solution for maintaining optimal wire conditions throughout winter.
The catenary heating cable and 8 clips weigh just 95 g/m—3.35 ounces per meter or 1.04 ounces per foot.

From Toronto to Calgary to Ottawa, Canadian light rail systems face a unique combination of challenges, including:
BLUE WIRE is engineered with these realities in mind, helping Canadian transit systems maintain consistent power delivery even during the most severe winter events. BLUE WIRE helps eliminate disruptions by:
For transit authorities, that means improved on-time performance and an overall better rider experience.
Manual de-icing—using expensive vehicles, maintenance crews, and harsh chemicals—is certainly disruptive. Beyond this, it’s expensive, inefficient, and poses potential a health and safety risks for workers. A BLUE WIRE system enables light rail operators to respond proactively, extend infrastructure life, and better manage operational, energy, and cost of ownership costs.
BLUE WIRE works equally well for problem areas—or across an entire light rail system in more extreme climates. The ability to heat overhead wires is especially helpful in areas prone to ice formation, such as:
Winter maintenance often requires crews to work in challenging conditions—on elevated systems, in freezing temperatures, or during active weather events. Compared to traditional de-icing methods, BLUE WIRE requires fewer emergency interventions, reduces maintenance crews’ exposure to dangerous conditions, and enables safer, more reliable rail operations for workers and passengers.
As weather patterns become more unpredictable, light rail transit systems need infrastructure that can readily adapt to fast-changing conditions. The prospect of a severe winter no longer has to mean outages, service interruptions, or hazardous, labor-intensive manual deicing.
With BLUE WIRE, Canadian light rail systems can maintain continuous power, reduce operational risk, and deliver reliable service all winter long. NIBE is here to help you implement the best autonomous catenary heating solution to keep your wires free of ice and snow, workers safe, and operations running smoothly.
