Burns & McDonnell completed a rail spur routing study for Duke Energy to serve an integrated gasification combined cycle (IGCC) expansion project at its Edwardsport Generating Station northeast of Vincennes, Ind. The rail spur is needed for coal delivery and byproduct sales for the life of the proposed IGCC plant. The potential route corridors ranged from four to 18 miles in length. The study included a constraint mapping analysis to identify seven potential rail corridors and a Kepner-Tregoe (KT) alternative selection analysis to narrow the number of potential corridors to five. A second KT analysis was conducted to select the preferred route.
Burns & McDonnell designed the preferred route, which consisted of approximately 10 miles of spur track, siding track and ladder tracks. The design includes horizontal and vertical alignment, grading and drainage details, three large stream crossings, nine private and six public road crossings (including a state highway crossing), and multiple ditch crossings. A ladder track system and siding were also designed to support coal unloading and sulfur load-out operations at the proposed IGCC Station.
