A Car For Every Purpose
In addition to the standard styles of cars, the railroads devised some curious and interesting special-purpose cars, mostly built in very small numbers. For example:
Pickle and vinegar carsWooden tank cars used by big food processors such as H. J. Heinz to move their products around the country in bulk quantities.
Live poultry carsOpen-sided cars, covered with wire mesh, that carried up to 5,000 chickens or 1,400 turkeys. An attendant aboard the traveling coop fed and watered his excitable flock. Now obsolete.
Hot-metal carsInsulated cars used to transport molten iron and steel around steel mills. In a few cases hot metal is transported over fairly long distances between mills.
Heavy-duty flatcarsTwelve- and sixteen-wheel flats were introduced in the 186Os to move large cannon. In more recent times deep-well flatcars were developed to carry high and heavy loads such as electrical generators.
Special tank carsSome petroleumcarrying tank cars were divided into three compartments to carry different refinery products. Other tank cars were designed for specific compressed gases or chemicals. Glasslined tank cars carried milk.
Ore carsPygmy hopper cars built short and heavy to handle their dense and weighty loads.
High cube boxcarsLong and high cars to handle light but bulky cargo such as buggies, furniture, and empty barrels.
