I am looking for any info, plans, drawings, profiles for the mainline from MA to ME through East Kingston and Exeter NH. Specifically, the original and subsequent construction details from 1839-1840 (original) to 1915 (subsequent) time frame. Bridge designs and pictures, rail bed profiles, etc. Of great interest is the construction done between 1890-1895 when the second rail was added.
Any help would be appreciated. I found the original survey and profile circa 1840 by James Hayward at the NH Historical Society if anyone else is interested!
