While perhaps not the most glamourous or breathtaking railroad photo ever but a photo of a behind the scenes piece of essential railroad equipment that's keeps the trains moving-safely and efficiently. The Knox- Kershaw yard cleaner with it's Cummins 240hp Tier 3 motor and 60 feet of highly efficient yard cleaning machine technology consisting of a ballast broom, bucket elevator system and conveyor plus more goodies not to mention a air conditioned, sound insulated, comfortable operator’s seat to get the job done. CN is currently using this particular machine to remove the taconite pellets from between the rails that fall, roll, or otherwise spill off the ore cars as they leave the U.S. Steel Minntac plant on the CN Minntac Sub.
