3rail. Black w/white. #14733, 14765 (ask if you need us to convert to 2rail for you)
This familiar hopper was an industry standard on many railroads since the 1930s. It was adopted by the AAR as a recommended design, but fell out of favor by the mid-1950s. While offering greater capacity over cars with conventional flat sides, the original open hoppers created corrosive interaction between acidic coal and the car’s joints, leading to costly rebuilding programs.
