A mass of information on the D&H main line has been accumulated since Where did the Tracks Go (1985) and Railroads of the Adirondacks: A History (1996) were published. Enough material is available now to warrant a new chapter.
A great deal of detail is available on the Main Line for several reasons. It is a main line with heavy traffic and many branches. It has been in service for many years: 160 into Whitehall and 133 through Westport, for example, as of this 2008 writing. Many changes have occurred during this long period. Many industries have risen, peaked, and declined. In addition, there has been a number of relocations creating a complex history: examples are the Port Henry tunnels, the Bulwagga Bay trestle, a shift from Mooers Junction to Rouses Point, and the junctions with both the Ausable and Chateaugay Branches.
Construction was complex, too: the line into the iron mines at Mineville did not initiate in Whitehall but in Leicester, Vermont. The Ausable line had been planned to be on the Main Line but became only a branch. The first railroad into Plattsburgh came not from Albany but from Montreal.
The segment from Whitehall to Rouses Point was chosen for inclusion in this atlas for two reasons. First, the railroad itself is organized into operational divisions, one of these being the Champlain Division from Whitehall (actually, from Lake Station, just north of Whitehall) to Rouses Point. Built northward from Albany, the line terminated near Whitehall for 25 years before being extended northward to Plattsburgh and Montreal. Second, inclusion of detail south of Whitehall and in Quebec would have made this Volume unwieldy. This is a work on the Adirondacks, and the bulk of the trackage should be in the Adirondacks. The segment on the Main Line from Port Kent to Rouses Point is not geologically in the Adirondacks, but is so tied in with branches into the Adirondacks that it is included.
