Atlas 2422 (Rivarossi 9336): 4 Bay Hopper Car. MStL 541002.

Prototype History:
The 1960s brought about a growth in car size (and capacity). Railroads that transported coal moved away from the older 2-bay 55-ton USRA standard to newer 90- and 100-ton three bay hoppers. These cars were effective and long-lived. Many railroads swapped out the trucks on these cars to increase the capacity to 100 tons. Many companies produced these, including Pullman, Bethlehem, Evans, Greenville, Trinity and Ortner. The offset side variant of these hoppers carried a little more capacity than their rib-sided cousins.
Road Name History:
The M&St.L dates to 1853 and received the M&St.L name in 1870. They ran west from Peoria, Illinois to Oskaloosa, Iowa. There the mainline split. The more heavily trafficked line headed north through Marshalltown, Albert Lea and ended in Minneapolis. The other route from Oskaloosa headed northwest to Des Moines, then traced a big arc thought Spencer, Iowa; Winthrop, Minnesota and back to Minneapolis. A northeast to southwest diagonal line connected these to parallel routes. In addition to some shorter branches, there was a very long branch from Winthrop, Minnesota to Aberdeen, Leola, and Akaska, South Dakota. Although they had St. Louis in the name, and they were known as “The Louie” by locals, they never went anywhere near that city. Total mileage during the 50’s ran about 1,400.
