This line dataset represents the railroad lines and those under construction in and near Mongolia in 1943. The features were described on the source map as "Railroad, broad guage (standard guage in China and Manchuria)," "Narrow guage railroad," and "Railroad under construction." The dataset was developed as part of the Mongolian 20th-century Historical GIS Database project. It is designed to integrate and align well with other datasets created as part of the project. It can be used for creating small to medium size maps of historical Mongolia and for analysis, as appropriate to the resolution. This data is only as accurate as the source maps upon which it is based. As such, the UC Berkeley Library does not guarantee the accuracy of the data. Researchers should use their own judgement about appropriate uses for this data. Users should please acknowledge and cite the “Mongolian 20th-century Historical GIS Database project” in any derivative works. The source map for this dataset is: "U.S. Office of Strategic Services, Research and Analysis Branch. Outer Mongolia and Tannu Tuva [map]. Scale 1:5,100,000.
