Here is a short video I took a few days ago of Mohawk, Adirondack & Northern 2453 (Alco, C425) heading out of its Utica, NY yard then entering the CSX main for the short trip to Rome, NY.

MA&N has trackage rights over CSX to Rome. There it serves an olive oil distributor (hence, "Olive Oil Express") and a manufacturer.

The Alco smokes it up quite a bit as it enters the main.
