This image of Alco and the Erie Canal was taken after the New York Central Railroad tracks were raised in 1907 and before traffic on the canal began waning in 1915.
The former Alco site off Erie Boulevard in Schenectady will soon be cleared to make way for redevelopment of the Mohawk River waterfront. More than 75,000 locomotives were produced by Alco. Photos offer a look at the plant through the years.
