Horses Of Different Colors. Bound for suburban Boston, MOAY rolls east past the decaying hulk of Johnsonville Tower, where the passenger main to Troy Union Station once diverged from the freight main to Mechanicville. Since AYMO/MOAY were revamped on 1/1/2010, they have frequently been colorful, and MOAY-17 was especially so, towing four former KCS/TFM units en route to new owner Pan Am.
