The name “Highliner” refers to two generations of double-deck railcars that are very similar in terms of appearance and technology. Each railcar has a length of 85 feet and four traction motors with an hourly output of 160 hp each. The first generation was built to order by Illinois Central for service in southern Chicago. Between 1971 and 1979, 130 and 36 were built by the St. Louis Car Company and Bombardier, respectively, which are no longer in service. The second generation was delivered by Nippon Sharyō between 2005 and 2016.
