The piers you see here once support a 133' high, 900' long trestle which spanned the Nashua River in Clinton, MA. Behind the photographer in the opposite direction is the face of the Wachusett Dam. Part of the original route of the Central Massachusetts railroad was submerged in the construction of the Wachusett Reservoir, which was constructed between 1897 and 1906. As a result, the route had to be signifcantly re-routed, and this trestle and an accompanying tunnel which is on the right on top of the embankment out of view, had to be built. Clinton also became well known to railroad enthusiasts as the last standing ground ancient B&M B-15 class 2-6-0s. In the late fifties, these locomotives and wooden passenger cars hauled commuters to Boston each day. As it turns out, the branch from Boston didn't last much longer than the Moguls, which last ran in May of 1956. Commuter service to Clinton ended in 1958 and the trestle which would be in this photo was removed in 1975.
