The Cleveland Construction Company was hired to build the line. All three rails were traditional "T" design rails laid on stone ballast. Wooden railroad ties were laid 2,816 ties to the mile and separated at standard gauge. Every fifth tie was long to support the third rail. The majority of the line was a double track, with a single track running from the Chicago Golf Club to Aurora. Roadbeds for the double track were wide and were surrounded by woven wire fencing. The third rail was usually placed on the inner sides of the double track, providing safety for residents and employees. The third rail was interrupted at railroad crossings, where a cable was placed underground to carry the current across the gap.
