On May 29, 1935, the Milwaukee Road inaugurated its Hiawatha high-speed passenger service between Chicago and the Twin Cities. The service featured all new equipment, led by the Class A streamlined Atlantic (initially loco nos. 1 and 2, with Loco nos. 3 and 4 added in 1936).
Here's a brief tribute with a photo of No. 3 from steamlocomotive.com plus a video of my Hiawatha Atlantic (2006, Lionel) pulling the 1936 ribbed cars on the Lionel Railroad Club of Milwaukee.
