Blue Is My Color. CSXT 4319 (GP39-2) was working on CSX Y224-17 in Locust Point, Baltimore, MD on the evening on June 17, 2021. The engine once served for Delaware & Hudson Railroad as 7419, and so is not a stranger to blue and yellow paint, albeit different shades. The job is switching out the Transflo Facility, with the C. Steinweg Fort McHenry Warehouse in the background.
