Corps of Engineers Maps - early 19th century
The Federal Government has been linked to railroads since the first charters were issued in the United States during the 1810鈥檚 and 1820鈥檚. Army surveyors from the Corps of Engineers were involved in the surveying and construction of the Baltimore and Ohio Railroad, the first operational railroad in the United States. Although no records remain of this work in the Cartographic Branch of the 威尼斯人娱乐场, many survey maps do remain of other early railroads. These include records created by the Corps of Engineers, , as part of internal improvements carried out by the Federal Government during the 1830鈥檚.
US Postal Service Maps
The U.S. Postal Service quickly realized the potential of railroads and began using them to carry mail. In 1838, all railroads in the United States were declared postal routes. Records relating to the Post Office Department may be found in .
General Land Office Maps
Following the conclusion of the internal improvement program, the Army continued to assist with the surveying of right-of-ways and bridge and tunnel construction throughout the ninetieth century. In 1850, The United States began issuing land grants directly to railroads in what would become known as the Public Land States. These transfers of public land to private hands helped to greatly increase the tax base of the country. The General Land Office, in the newly established Department of the Interior, was assigned the responsibility of supervising the railroads. Their duties included surveying public lands for potential railroad routes, administering land grant policy, and resolving issues involving right-of-way through public lands such as national parks and Indian lands. The records of the General Land Office, including right-of-way maps and railroad land grant maps, may be found in .
The Pacific Railway Act of 1862 - Surveys and Route Maps
As the country continued to expand westward, President Abraham Lincoln felt it imperative that a railroad should connect the continent from coast to coast. The Pacific Railway Act of 1862 provided the financial and legal groundwork for this undertaking. Records in the Cartographic Section relating to the transcontinental railroad consist of survey and proposed route maps from both military and civilian agencies, including the U.S. Senate (), the Office of the Secretary of the Interior (), the Office of the Chief of Engineers (), the Office of the Quartermaster General (), and the Adjutant General鈥檚 Office ().
Inventions and Patents
With the coming of the second industrial revolution during the second half of the ninetieth century railroads underwent a rapid transformation and advancement in technology. These advances were lead by thousands of new inventions, from larger and more powerful steam engines, to improved track designs, to safer breaking systems, to more luxurious passenger cars and specialized freight cars. These inventions were documented through patent application files submitted to the Patent and Trade Mark Office (). The Cartographic Section maintains the patent drawings from these files for Utility Patents 1 to 1,000,000.
Railroad Valuation Maps, 1915-1920
This series contains the most complete and detailed set of railroad maps held by the 威尼斯人娱乐场. Maps exist for nearly all of the major freight carrying railroads operating during the World War I time period, when total main line trackage reached its high-water mark of 254,000 miles.
The maps are arranged in our Catalog by the name of the railroad. To locate which railroad ran through a specific geographic area, consult this commercial atlas from 1914:
Once you determine the name of the railroad, you may narrow your search by determining the specific Valuation Section. These sections were assigned by the Interstate Commerce Commission during their valuation survey and can represent anywhere from one map to several hundred. To find specific valuation sections, consult the system index map for each railroad. Locate your site on the system index, and find the associated valuation section number. For example, these are the system indexes for the Atchison, Topeka, and Santa Fe Railroad: . In the second image, you can see that the section of line running from Dodge City to Coolidge is valuation section 32. There is often a more detailed index filed with each valuation section. You can use this section index to locate specific map sheets.
Individual maps are added to our Catalog as they are digitized on an ad hoc basis. If you do not find images of the Valuation Section or map sheet you are searching for you may visit our research room in College Park, Maryland or hire a private paid researcher to view and copy the maps.

The United States Government was also becoming involved in projects and other activities on foreign soil. A large number of maps relating to foreign railroads may be found within the holdings of the Cartographic Branch. These include relating to the Intercontinental Railway Commission in South America (Record Group 43), maps of railroads constructed or studied by the Corps of Engineers (), and maps of railroads compiled for intelligence purposes by the War Department General and Special Staffs ().

Railroad Mergers and Consolidations
For a number of reasons, including government regulation, increased competition, legal and labor issues, and financial losses stemming from maintenance obligations, railroads suffered greatly during the Great Depression and the post-war years of the mid to late twentieth century. These hard times are documented through maps relating to railroad mergers and consolidation. Maps relating to consolidation studies created by the Reconstruction Finance Corporation during the 1930鈥檚 are located in. created to document land transfers authorized by the Regional Rail Reorganization Act of 1973 may be found in Record Group 21.
