The track and roadbeds were built to best practice standards as the new lines were envisioned to be the permanent rail system for the island.  Overhead wires were constructed and carried 600 volts of direct current electricity. 

            Compared to the early railroad track length (3,800 feet), the new electric line needed 14,700 feet of track to reach Topside.  This length was needed because it wound up the steep curves and banks. In all, the track length was estimated to complete six complete circles but the average grade was only 3.4%.
