Delaware & Hudson Railroad Straight Line Maps [In progress]
Scope and Contents
The collection consists of three little booklets from the Office of the Chief Engineer of the Delaware and Hudson Railroad Corporation detailing the railroad properties of the Pennsylvania Division Main Line including the WilkesBarre Connecting Railroad [a “paper railroad” jointly owned by the Delaware & Hudson R.R. and the Pennsylvania Railroad to facilitate interchange traffic between the Pennsylvania Railroad at the Buttonwood Yard and the Delaware & Hudson at the Hudson Yard], Plymouth Branch, Buttonwood Branch, Branch No. 3 and No. 5; the Susquehanna Division including the Saratoga Branch and Cooperstown Branch; and Champlain Division including the Baldwin Branch, Ticonderoga Branch and Ausable Forks Branch, up to Montreal, Canada. Apparently the large railroad map blueprints were pieced together into straight line maps, “stitched” together and folded like an accordian into a booklet size to fit a railroad inspector’s coat pocket. This is apparent in the form of reproducing the maps from their original format into an easy usable form. Many of the maps that are in the little pocket booklets show a form of reproducing these maps from a larger format - examples being photographing of folded corners, blurred images and mirror images [reversed letters] in the process of stitching together the related maps into a Division scheme which was further detailed into related Branches making the layout much easier to handle than the original larger rectangular maps.

Biographical / Historical
Delaware and Hudson Railroad Corporation incorporated in 1928, in 1930 the Delaware & Hudson Company which grew out of the Delaware and Hudson Canal Company, was transferred to the D & H Railroad. In 1938 the D & H Railroad Corp. set out as a bridge line [archives.albany.edu/description] carrying large amounts of freight between railroads. Information on this aspect of railroading is located in the Bridge Line Historical Society Collection 1870-2024 in the M.E. Grenander Dept. of Special Collections & Archives at the University of Albany [New York]. The Valuation Act of 1913 from the Interstate Commerce Commission attempted to help set in place the manner of determining the valuation of railway property to calculate the rates for transportation of freight along the railroad lines [archives.gov/files]. This system originated between 1915-1920. Straight line maps are also called “signal line maps” and produced to display features along the road beds such as bridges, buildings, intersecting roads, speed limits [http:raildata.railfan.net], number of tracks. They were originally called Railroad Valuation maps.
