FIMX 4021, one of Lhoist's two B23-7's that are of Southern Railway heritage, works the mine shuffling hoppers around for the loading of limestone products for shipment. Lhoist North America's Crab Orchard operation is unique in that not only do they ship much of their product out on their own railroad (a very scenic one too, no less), but they also do it while operating two of the only remaining high hood GE locomotives in existence, of which, it's believed that there are only 4 left in the USA (three B23-7's & a U23B).
