|MILW H-16-66 524, Escanaba, Michigan, November 9, 1975, photo by J. H. Nixon, Chuck Zeiler collection. There is conflicting information about this locomotive, the following is from the book, 'Faribanks-Morse Locomotives In Color', by Jim Boyd: The Milwaukee Road was one of only four customers to buy the H-16-66 Baby Trainmasters. They were delivered in two batches, numbers 2125-2127 (later 550-552) were built during August-September 1953, and 2128-2130 (later, 553-555, later still 547-549) were built during September 1953, and all were classed 16-FRS-6 by the Milwaukee. Somehow, the second batch had lower constrution (serial) numbers.The book does not connect this road number to any previous number, but this web site ( http://www.trainweb.org/milwaukee/roster.txt ) claims that 524 was built as 2128, then renumbered to 553, then 547, then 524. The web site offers c/n 16L-757 as the serial for number 524. Take your pick. It appears that 524 was out of service on January 1976, and sold for scrap to Precision National in June 1976. Finally, consulting the book, "Milwaukee Road Locomotives, Volume Three", by Thomas J. Strauss, this locomotive was built as 2128 (c/n 16L693), renumbered to 553, then 547, then 524, equipped with MU connections at both ends, no dynamic brakes. Only 60 H16-66's were built, with the C&NW owning 50, the Milwaukee owning eight, Alcoa owning one, and TVA owning one.
