GTW GP9 No. 4554 leads a trio of GTW locomotives across the diamond in Durand, Michigan on May 26, 1984. The diamond is the crossing of the GTW’s Flint and Holly Subdivisions. GTW No. 4554 was built by EMD in March 1957 for Central Vermont. Its origins on Central Vermont accounts for the dynamic brake blister on the long hood. Locomotives that were purchased for service on GTW, like trailing unit GTW GP18 No. 4703, were not equipped with dynamic brakes and therefore did not have a dynamic brake blister on the long hood. No. 4554 was retired in July 1991 and was sold to the Adrian & Blissfield Railroad where it operated as No. 2 and later as No. 1772. Photographer unknown, Glenn Courtney collection.
