|MILW F3 86A and CFA16-4 27C at Bensenville, Illinois on February 14, 1965, photo by Chuck Zeiler. Number 86A was built as F3A 83D in February 1949 (c/n 6314) on EMD Order 997A, classed as 15-EF on the Milwaukee. As delivered, it was the rear cab unit of locomotive set 83A-B-C-D. During late 1949, this four-unit locomotive was separated into two two-unit locomotives for assignment to lighter trains that did not need four units and where overall speed between terminals was not important. Numbers 83D-C were renumbered to 86A-B, and both retired and traded to EMD or GE on new power a month after this photo. Number 27C was built in August 1951 (c/n 16L488), class 16-FF. I cannot find a retirement date (yet).
