FT 2404: CB&Q 190356 & 190359 33' 2-Bay Rib Woodchip Hoppers Once considered trash, woodchips morphed into a valuable commodity during the 20th Century. Their use as pulp in paper production, bedding and fill in farm and ranch, mulches for gardening, playground surfacing, forest fire prevention, and not least as an alternate fuel source, propelled them into being a profitable industry. And of course, railroads would be responsible for transporting this modern bounty. What vehicles better than hopper cars to transport it? The lighter weight to volume of woodchips compared to coal or gravel allowed for larger capacity cars, and to achieve this, all manner of hopper extensions were conceived. From wood planking and braced plywood to welded steel and even scrap parts from old or wrecked cars were utilized to increase capacities. All woodchip hoppers feature custom woodchip loads from Hay Brothers. All cars are equipped with Full Throttle's own Bettendorf trucks, metal wheels and knuckle couplers.
