Manufacturer and Powerplant: Ringling Bros Circus Rolling Stock was acquired from various railroads across the country who sold their old cars due to them closing down. Most cars come from B&O railroad after it went out of service. The Circus does not own a private locomotive instead maintains agreements with Union Pacific Railroad (West Coast) and CSX Railways (East Coast) BNSF Railroad (North West) and Santa Fe (South West) for routes to major cities. Rail cars marked "RBBX" belong to the Circus, others may have been loaned or rented by the railways escorting them.

Fare Collection: Not Applicable, Train not open to public during travel tours given when show is at rest for one month usually December.

Livery: Originally yellow, the Circus Train is identified by its steel silver rail cars fitted with the red Ringling Bros. Circus signs and posters. Smaller trailers and other vehicles are sometimes painted white.

Innovations: The arrival of the circus train in any major city brings an overwhelming sense of happiness and excitement. The sheer amount of logistics involved in this production are as amazing as the show being performed. The circus employs performers from all around the world as well as full time maintenance workers, catering personnel and veterinary staff to care for the animals used in the show.
