Atlas 5556 - Pullman Standard 4427 Covered Hopper - ADM #3112
Introduced by Pullman in the mid-1960s, the PS-4427 low side covered hopper became the backbone car for many of the large grain hauling railroads as well as the car of choice for many leasing companies. The 4427 also was used to haul malt and sand products, which increased their venerability. Many of these hoppers wore colorful, diverse schemes, which featured large logos or lettering. Some of these cars still exist in service today.
