CN said herbicides are primarily applied to the ballast – the rock bed supporting the tracks – and in select areas around signals and communications equipment.

“Herbicide application on the ballast section is completed with spray trucks or spray trains fitted with downcast nozzles that spray a short distance above the ground surface with shrouded booms, specially designed to limit herbicide drift into non-target areas,” the company said.

Vegetation outside the track area may also be managed using mechanical methods such as mowing or brush cutting, with limited herbicide use to control invasive or noxious weeds.

CN noted the schedule is subject to change due to weather or operational factors.
