The part relevant to the editorialized headline: “The MBTA will perform work in December to replace the wooden overhead catenary wire “trough” in the Green Line tunnel, which is original to the tunnel’s construction in the late 1890s. The trough houses the Green Line’s overhead wires and will be replaced with a modern, more durable, metal trough.”
