The body style has also been sold by Eastern Seaboard Models under the ESM branding. The model is available in both 3-Bay and 6-Bay variations.

Prototype History: ACF introduced their roundish cylindrical hoppers in the early 1960s. The cars differed greatly from the ribbed sided hoppers of the era. They have been made in 3-bay and 6-bay variations. These cylindrical hoppers were superseded on ACF’s production line by the Centerflow in 1964, a revolutionary design that influenced later covered hopper types. In the late 60s or early 70s Canada came out with 4-bay covered hoppers that appear to be derived from ACF’s pre-Centerflow cylindrical hoppers. These cars were used by CN, CP and various smaller Canadian shippers. There is some question as to why the Canadian builder based their design off the older cylindrical and not ACF’s newer Centerflow. It was likely a patent issue and copying it could have triggered legal action against the Canadian builders. There are also certain structural design differences between the cylindrical and centerflow cars and perhaps the decision to copy the cylindrical was based on the greater volume capacity of the cylindrical design.

Road Name History: IMC Global (also known as International Minerals and Chemical Corporation) was a mining and production company, previously listed on the S&P MidCap 400. It was originally founded in 1909 as International Agricultural Corporation. In 2004, IMC Global merged with Cargill, Inc.'s crop nutrition division to form The Mosaic Company, a crop nutrition company.

IMC Global was incorporated as International Agricultural Corporation on June 14, 1909 by Walderman Schmidten in the state of New York. A native German, Schmidten moved to secure entire capital in mines from his home country; he was successful in doing so with the Kaliwerke Sollstedt Gewerkschaft. Phosphate and potash production facilities were acquired in Tennessee and Florida. Capital stock of the International Agricultural Corporation was originally fixed at $15 million in July 1909, but increased to $36 million by April 1911. As World War I broke out, demand for fertilizer declined while that for sulfuric acid skyrocketed. International Agricultural Corporation was the largest owner and distributor of phosphate in the United States by the 1920s.
