The
increased volume of coiled steel transportation gave rise to a
new purpose-built freight car. Previously rolls of coiled-steel
had generally traveled in specially equipped gondola cars. In
the 1960’s a lighter type of car emerged specifically for
hauling coils of steel in an integral trough. The car type gained
popularity and eventually over 17,000 cars were built. Atlas’
model replicates a 42’ design with a distinctive fishbelly
side sill.
