Available exclusively for charter is the Santa Fe caboose, built in 1930, numbered 999418. Visible at the rear of trains all across the Santa Fe system, this caboose was retired in 1985 and purchased by Bert Dockall of Rockdale, TX. Since the first days of the Austin & Texas Central Railroad, it has been leased to the Austin Steam Train Association by Eagle Rail Services.

The caboose is isolated from the rest of the train and is heated, but not air conditioned. The caboose is available on Hill Country Flyer and runs at the rate of $750. The caboose seats 12 people.
