Abstract
A 100-125 ton capacity steel flat railcar hauls steel slabs with the capacity to alternatively haul steel coils. The car design allows steel slabs of various sizes and weights to be hauled efficiently by placing the slabs longitudinally on the car. The slabs are captive by side stanchions restricting the slabs from lateral movement and bulkheads at the ends preventing longitudinal movement of the slabs. The weight of the slabs is concentrated near the bolsters through raised mounting platforms. The railcar also has the capability to haul steel coils in a built-in trough over the bolster area. The end bulkheads restrict and position the steel coils allowing the coils in each trough to have a gap between them for ease of loading and unloading. The side stanchions restrict the steel coils from unwanted unloading due to coupler forces.
