This abandoned railway line ran from Shenectady behind the Alco Plant Site and generally followed the Mohawk River. It went through Aqueduct, Niskayuna, Crescent, Cohoes and then crossed the Hudson River to hit the NYC line on the east side of the river at Green Island. The line was abandoned in the 1970s and early 1980s. Much of it has been converted into a trail, and 12 miles between Crescent and Rexford has been incorporated into the Mohawk-Hudson Bikeway. The ROW is still easy to see in almost all areas.
