MTH - RailKing Freight Cars - Gondola Car w/45 Degree Crossover - O Scale 3 Rail 

On its customer Web site, the Union Pacific Railroad characterizes a gondola as an "extremely sturdy open design" for carrying "rugged unfinished commodities"; its "large flat interior design with side walls" is described as "more flexible than a flat car." These qualities make the modern gondola particularly popular with the steel industry, for transportation of loose materials like scrap metal, waste, coke, and slag as well as finished products like iron or steel plate, pipe, structural steel, and rails for railroad track. Other commodities commonly shipped in these versatile cars include mineral ores, granite slabs, gravel, logs, lumber, railroad ties, large crates, and even prefabricated railroad track, also known as "panel track."
