Model GP28 with just over two-dozen domestic examples built may be considered one of General Motors Electro-Motive Division more obscure diesel-electrics.

It was contemporary with the relatively popular GP35 with which it shares a similar external appearance.

Where EMD’s GP35 was a high-horsepower model using a turbocharged variation of the 16-567 diesel to deliver 2,500 hp, the GP28 used a 16-567D1 aspirated with a Roots blower and delivered just 1,800 hp.

The GP28 was only in production for a few months during 1964 and 1965, and may be viewed as a transitional model between the GP18 and GP38.

I don’t recall having ever photographed a GP28 in action until last Friday.

Kris Sabbatino and I were fortunate to capture Mass Coastal GP28 2009 during the course of its daily duties on Cape Cod.

Working with my Nikon Z6, I made these photos as it worked near the Cape Cod Canal lift bridge at Bourne, Massachusetts and nearby at Monument Beach on the Falmouth Branch.
