After a 1991 derailment near Batesville, Mississippi, CN Railway delayed repairs to a damaged truss on Bridge J448.34 due to high repair costs. In 2005, however, repair was initiated when tests indicated that the damaged truss was nearing the end of its safe service expectancy. Since the cost of repair for the truss included pile-driving equipment in all bids, CN took an alternative route to using a pile-driving crane by expanding on a shoring concept that utilized cantilevered beams to support the truss while repairs are being conducted. The cantilevered shoring system used by CN’s contractor, however, were more than twice the length of standard trusses, and were also installed around the floor system of the existing track in order to avoid fouling. This method not only avoided the necessity of expensive pile-driving, but also allowed for train traffic to continue most of the time the truss way being repaired.
