In 1885 a livery and stable operator from Toledo, Ohio by the name of Harrison Arms formed the Arms Palace Horse Car Company to service this market niche. Arms' cars resembled the passenger cars of the day; they featured clerestory roofs and end platforms and came equipped with passenger car trucks (as they were intended for passenger train service). The units were segregated into two separate compartments, each containing eight individual stalls. By the late 1880s Arms had acquired two competing firms, Burton and Keystone. While the cars operated by George D. Burton closely resembled the Arms design, the Keystone Company's cars were much more utilitarian in design as they were intended for transporting animals of lesser value and inclusion in standard freight train consists. The Keystone fleet eventually grew to more than 1,000 cars. Many of the cars finished out their days in maintenance of way (MOW) service. Circus use Many circuses, especially those in the United States in the late-19th and early-20th centuries, featured animals in their performances. Since the primary method of transportation for circuses was by rail, stock cars were employed to carry the animals to the show locations. The Ringling Brothers and Barnum and Bailey Circus, which traveled America by rail until it closed in 2017, used special stock cars to haul its animals. When a Ringling Brothers train is made up, these cars are placed directly behind the train's locomotives, to give the animals a smoother ride. The cars that Ringling Brothers used to haul elephants were custom-built with extra amenities for the animals, including fresh water and food supply storage, heaters, roof-mounted fans and water misting systems for climate control, treated, non-slip flooring for safety and easy cleaning, floor drains that operate whether the train is moving or not, backup generators for when the cars are uncoupled from the locomotives, and specially designed ramps for easy and safe loading and unloading. Some of the cars also have built-in accommodation for animal handlers so they can ride with and tend to the animals. Fish cars In the 1870s the railroads of America were called upon to transport a new commodity, live fish. The fish were transported from hatcheries in the Midwest to locations along the Pacific coast, to stock the rivers and lakes for sportfishing. The first such trip was made in 1874, when Dr. Livingston Stone of the U.S. Fisheries Commission (which later
