Mohawk, Adirondack & Northern operates a 45-mile line between Utica-Boonville-Lyons Falls NY. There are no active customers in the 10-mile stretch of track between Boonville-Lyons Falls. Consequently, the MA&N has stored cars on this part of the line for at least the last ten years. Of late, it's been tank cars.

On July 30th, the MA&N dispatched three of their vintage engines (Nos. 2455, an ALCo C425 built in 1964 for Erie Lackawanna, 2456, also a C425 built in 1964 for Erie Lackawanna & 2042, an M420W built in 1973 by Montreal Locomotive Works) from their Utica yard to retrieve 79 tank cars. There are still several hundred left on the line.

This video includes views of the engines running north with just a single covered hopper to be used as a spacer car as well as scenes of the big branchline freight southbound through the village of Boonville.

This line is otherwise very quiet with the only two customers in Boonville. The Adirondack Railroad, however, has trackage rights over the first 23 miles in order to reach their home rails in Remsen's Snow Junction (after which it's 85 miles to the end of their tracks in Tupper Lake NY).
