The eventual downfall of the "Air Line" scheme arose as a result of the capital expended on crossing Coffee Creek, a minor watercourse running west of the Wabash Railroad bridge. To keep to the advertised grade prescribed by the incredibly stringent engineering specifications, the GSB&C engineered a monstrous fill across the little creek's valley, 180 feet (55 metres) wide and two miles (3 km) long and containing a steel trestle for stability. The extent of this work meant that the line only opened to Goodrum on 1 November 1911.
