Massachusetts Coastal GP7U 2006 was originally Santa Fe Railway GP7 2689.
On our visit to Cape Cod, we found this antique from 1951 basking in the late afternoon sun at the Hyannis yard.
I made a selection of photos from different angles, using different cameras and different lenses, to show how the angle of the sun and other differences can greatly affect how color is perceived and recorded.
So which is the ‘true’ color of the locomotive? There isn’t any ‘true’ color, it all depends on how you perceive it in the moment. The appearance of paint color changes with as the light changes.
Cape Cod Central’s cranberry is a difficult color in part because it is a mix a blue and red hues. Blue is greatly affected by the color of the sky; red by the sun. With a polarized sky and the sun low on the horizon the angle of view (and angle of reflection) affects the apparent color more than on a day with more diffused sunlight and the sun higher in the sky.
Complicating matters for the modern day photographer is that different camera sensors and color profiles also affect the way that color is recorded.
In April, Kris Sabbatino & I made a visit to Cape Cod, where we spent a morning at West Barnstable photographing the Mass Coastal and visiting a chicken farm.
Mass-Coastal operated a ballast train with its rare GP28 (as previously featured on Tracking the Light). Working with my vintage Canon EOS-3 with 100-400mm image stabilization zoom, I exposed a slide sequence on Kodak Ektachrome E100 reversal film.
The film was processed by AgX lab in Michigan, and last night I scanned a few of the slides using a Epson Perfection V600 flatbed scanner powered by Epson software. After scanning, I imported the TIF files into Adobe Lightroom for color and contrast fine-tuning.
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.
Kris Sabbatino and I were very lucky to catch a relative unusual move on Cape Cod last Friday (April 23, 2021).
Mass Coastal’s rare EMD GP28 (road number 2009) led a train of MassDOT ballast cars eastward on the former New Haven Railroad at West Barnstable, Massachusetts.
I was delighted to catch this unusual locomotive (one of less than three dozen built) in good sunlight. In addition to this digital photo exposed using my Nikon Z6, I also made a sequence of color slides with my Canon EOS 3 with 100-400mm lens.
On Thursday afternoon, Kris Sabbatino and I arrived on the Bourne, Massachusetts side of the enormous Cape Cod Canal lift bridge just as the Massachusetts Coastal Energy train was approaching to cross.
Fortuitous timing considering we had left Center Conway, New Hampshire after 930am.
I exposed these photos using my Nikon Z6 digital camera and modified the color, contrast, and level using Adobe Lightroom.
