Valuation Map Collection

The Hays T. Watkins Research Library and Archives is home to a large collection of railroad valuation maps. From 1915 to 1920 railroad engineers working for the Interstate Commerce Commission (ICC) created these maps to inventory extant railroad structures and property. These maps detail land owned by the railroad, including the right-of-way, track layout, buildings and structure locations, and other engineering details for the entire U.S. railroad system mile by mile. Almost all of the maps are ink drawn on linen, measure 25" by 54” and cover between one half mile and four miles of track. Our collection is unique because a lot of these maps were originally kept here at the Mt. Clare Shops, while others were donated by former B&O employees as shops, towers, and stations closed.

 

We are undertaking a digitization project in order to preserve the maps within our collection and will make them available to researchers as they are scanned. Below you will find a list of maps currently available, which is updated periodically.

We are able to take requests to scan maps at this time. If you are working on a project and need a specific map digitized, please email the Archivist at archivist1@borail.org with the following information:

 

-       Name of the railroad during the period 1915-20

-       Location of the town or geographical area

-       If known, the valuation section (ex. 1-MD-V17.1, or 77-OH-V127.2, a number often reflected in the 1954 Form 6 booklet available through the B&O Railroad Historical Society Store.)
