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.
