CNWs secondary lines in Minnesota offered some interesting motive power into the early 1980s. In addition to the famed "Alco" line, the former Minneapolis and Saint Louis, which crossed the Alco line at Waseca, could provide some interesting consists, particularly during the grain rush. By 1980, the CNW had retired the majority of its F-Unit fleet, but a number of former Chicago Great Western F3s were kept around when extra power was needed. Here's F3A 211, F3B 309, F3A 205, and F3A 215 leading a long train north of Waseca. One can see two vintages of F3s in this set, with 205 sporting chickenwire, but 211 and 215 wearing stainless steel grilles more commonly associated with F7s and F9s.
