Between 1914 and 1921 maps and other documents were created by the railroads in the United States in response to the Valuation Act of 1913, which empowered the Interstate Commerce Commission to require an inventory of property owned by the nation's railroad companies to determine the value of their property, the net worth for each railroad, and as a means to set freight rates. The valuation maps available here, dated June 30, 1915, show property owned and operated by the New York, New Haven & Hartford Railroad Company, better known as the New Haven Railroad, which was the predominant railroad line in southern New England between 1872 and 1968; The Railroad Valuation Maps show detailed track plans of the New Haven Railroad's right-of-way as well as other property such as railroad stations, roundhouses, yards, and service buildings. The dates the parcels of property were purchased by the railroad or one of it's predecessor lines are available on each map. The maps were originally created to account for the railroad company's property, to report to the Interstate Commerce Commission who used this information to establish freight rates. The maps can now be used to account for the history of the ownership of certain parcels of property, to verify property ownership and dates of sale or transfer to the railroad, and as part of an examination into changes in the property previously owned by the railroad.
