Greenville 100 Ton 2 Bay Hopper

Prototype Information

The Greenville 34-foot 100-ton 2-bay hopper debuted in the early 1970s to handle the heaviest, densest commodities on the rails. The Greenville Steel Car Company optimized this short, rugged design for materials like iron ore, copper concentrates, and heavy stone. By keeping the car length to just 34 feet, Greenville ensured that the 100-ton load remained concentrated directly over the trucks. This compact footprint allowed railroads to maximize the tonnage of a train without exceeding length limits on sidings or loading tipples.

The Southern Pacific became one of the most famous operators of this design, acquiring large fleets for its heavy aggregate and ballast service. These cars became the workhorses of SP rock trains, moving massive quantities of granite and gravel across the Western United States. Their steep interior slope sheets and large discharge gates allowed for rapid unloading of sticky or heavy minerals. Even after the Southern Pacific merged into Union Pacific, many of these durable cars continued in service, proving the longevity of Greenville’s high-strength engineering.
