The Great Lakes Central (GLC), originally called the Tuscola and Saginaw Bay Railroad (TSBY), is a regional railroad in the state of Michigan.  Operations for the TSBY began in 1977 and continue today.  The photos in this section focus on the details of locomotive #391, City of Owosso, as the locomotive appeared in the summer of 2007.  Many thanks to the GLC for supporting the NMRA in providing safe access to the service facility and overall gracious hosting of our tour group.

Locomotive:

The GP35 was manufactured by General Motors Electro Motive Division, as a 4-axel diesel.  The power inside the locomotive is a EMD 567D3A 16-cylinder engine that could generate 2500 horsepower.  A total 1250 locomotives were built for American railroads, 83 were built for foreign railroads. (Wikipedia)

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 railfans generally categorize locomotives into phases.  The phases designate changes in  components that that ocurr during the manufacturing run of the locomotive.  The manufacturer does not determine what phase a locomotive is, the community uses phases to dicuss 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 lilkely 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.
