Maine Central Wood Chip Hopper #3502 Take your hoppers to new heights with these new models! As traffic sources changed, railroads often repurposed older equipment for new uses. Hoppers originally designed for coal could also haul coke or wood chips, but with their lighter density there was room for more capacity. Many railroads simply worked around that issue by raising the sides. Equipped with a newly tooled extension, these hoppers are ready to go into service on your layout hauling coke, wood chips, sugar beets - whatever you'd like to pile high! Each road name is available in two road numbers. SKU: 2219271 Dimensions: Length: 9â Gauge: S Gauge Minimum Radius: R20 Road Number: 3502 Manuals Find the latest manuals in our support section.
