of Badger Mining Corporation, Preferred Sands of Wisconsin LLC, Atlas Resin Proppants LLC and Taylor Frac LLC.
The improvement program will permit the transportation of heavier loaded frac sand freight cars weighing a maximum of 286,000 pounds, thereby increasing the volume per car, generating increased productivity for customer car fleets and increasing train speed for CN.
CN will improve the 74-mile section of the Whitehall Subdivision between Wisconsin Rapids and Blair, Wis., in three years rather than four. Work began in 2012 and the full program should be completed by December 2014.
Jean-Jacques Ruest, CN executive vice president and chief marketing officer, said, "We are investing in increased rail capacity on the Whitehall Subdivision to help move more frac sand and to develop a more robust supply chain for our customers in Wisconsin to connect with the oil and gas shale basins in North America."
