Cold morning, heat waves. As CSX 1712 (SD40E3) leads Y101 down the Fremont Secondary on the morning of Sunday, February 10, 2019, the chill in the air is evident from contrast between the exhaust and the ambient air. Signs for “Triboro Br” and “La Guardia Airport” set the scene as the Borough of Queens in New York City, CSX’s only trackage in NYC outside of the Bronx.
