- Dahlinger, Fred Jr. Trains of the Circus, 1872-1956. Hudson, Wis.: Iconografix; 2000. 126 p.Notes: Published in conjunction with the Circus World Museum (located in Baraboo, Wisconsin), this volume consists primarily of photographs showing how trains were used by circuses as they moved from place to place throughout the United States for their short engagements. Included photographs show both the railroad cars specifically designed to meet the requirements of transporting the specialized circus equipment and livestock, as well as the techniques developed to efficiently load and unload a circus; many of the examples provided were drawn from the files of the Ringling Brothers’ circus, which had begun in Baraboo and which remained headquartered there for many years.
