I'd often wondered how the large Indian elephants (Elephas maximus indicus) in the circus made it through the doors of the former baggage cars converted to elephant cars on the Ringling Bros. and Barnum & Bailey Circus train. It turns out these pachyderms are trained to kneel enough to get through the large doors, although for the elephants the doors are not all that large and these cars were certainly not roomy when loaded. These elephants must have despised riding in these cramped cars. This car, RBBX 63004, was built by St. Louis Car Company in 1962 as Union Pacific Baggage/Storage 5764. UP eventually placed it in Maintenance-of-Way service, and numbered it 904292 and, later, 904701. It was sold to Ringling Bros. and Barnum & Bailey in 1994, and the circus enlarged the interior to some degree. The train is seen unloading at Anaheim, California's, Honda Center (on Union Pacific's Marlboro Branch) on July 24, 2013.
