Stray current is a major consideration when constructing Light Rail projects. Future corrosion of the rails and metallic assets in the ground (gas mains, earth stakes, cables, foundations, etc.) should be prevented by any means necessary.
For the Canberra light rail project, our company was able to play an important role in this aspect. In 2017, 12 km of highly insulating edilon)(sedra Corkelast® ERS (Embedded Rail System) was installed as part of a brand new Light Rail network for Transport Canberra.
Two years after the installation, the Transport Canberra Stray Current working group carried out field tests to measure the electrical insulation values under different climatological circumstances. Formally reported measurements show the embedded rail system continues to demonstrate an excellent seasonal trend. Rail-to-earth resistance results in wet conditions surpass 20 ohm·km, while dry conditions show phenomenal readings in the order of 60 to 80 ohm·km!
The challenge
Elimination of stray currents >> prevention of corrosion of rails and metallic assets in the ground.
The solution
