Locomotive #391 is a GP35 formerly owned by the Ann Arbor Railroad as locomotive #391. The locomotive was originally built in May of 1964 with a serial number of 28997. This locomotive was in a group of 10 ordered for the DT&I.
Modelers and rail-fans generally categorize locomotives into phases. The phases designate changes in components that that occur during the manufacturing run of the locomotive. The manufacturer does not determine what phase a locomotive is, the community uses phases to discuss specific locomotive details. The phase information for #391 was referenced from the Diesel Modeler’s Mailing list by David Thompson.
The phases for locomotive #391 is likely Ia2 – Ib1 as noted by the three latched engine doors on the side of the locomotive. Locomotive #391 is equipped with Type B trucks salvaged from Alco FAs that the railroad traded in. The engine does not have dynamic brakes.
More information on the TSBY can be found in the March 1984 issue of Railroad and Railfan by Bob Wise.
