The Iowa Traction Railway Company (reporting mark IATR), formerly the Iowa Traction Railroad Company, is an electrically operated common carrier railroad running between Mason City and Clear Lake, Iowa, United States, and also serving Rorick Park near Mason City. It can trace its roots back to the Mason City and Clear Lake Railway, which was founded in 1896. The shops were situated in Emery, the midpoint between the two namesake towns. Passenger service began on July 4, 1897. Freight has been the major source of income since the beginning and has been the only source since the charter for trolley service in Mason City expired August 30, 1936. The Mason City and Clear Lake Railway's name was revised slightly to Mason City and Clear Lake Railroad in 1950, when new owners took over.
