Signal gantries operate similar to traffic lights, facilitating the safe passage of trains by indicating when a line ahead is occupied and ensuring sufficient space between trains or to regulate train speeds.
With the introduction of double-stacked freight trains, our construction contractor McConnell Dowell is undertaking works on the signals along the North East rail line to achieve the required clearance.
In most cases this requires a full replacement with a taller signal structure.
McConnell Dowell will replace five cantilever signal gantries (pictured above) and three signal masts for Inland Rail in Victoria.
