On 28th November 2012, the final 6 wagons of a 70 wagon fully laden coal train derailed while crossing the elevated Cox’s Creek bridge. The line serviced the Boggabri and Narrabri coal mines and the wheat harvest was underway, requiring multiple grain trains. Bridge and Civil were engaged by ARTC to assist with getting the bridge open to traffic.
The damaged spans were removed and replaced with spans from the least elevated end of the bridge that, in turn, were replaced with a temporary embankment of rock. We demolished and rebuilt several concrete piers, working 7 days a week to get the bridge reopened within a month.
Following the November 2012 derailment, ARTC awarded Bridge and Civil a contract for the full reinstatement of the bridge.
The work included the removal of the temporary rock embankment [and the processing of that rock into rail ballast], installation of 4 new steel girder spans, fitted transoms to the new spans and installed Huck bolts to previously installed bridge transoms and the installation of new safety walkways to the entire bridge.
The work was carried out in a 4 day track possession for removal of the embankment and installation of the new spans.
