Description: The Rail Mileposts dataset was compiled on June 15, 2025 and was updated on September 01, 2025 by the Federal Railroad Administration (FRA), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The FRA Mileposts feature layer is a spatial reference file compiled from multiple sources and displays approximate point locations of mileposts along the FRA rail network wiithin the United States. It is intended for general reference purposes only. The rail lines and mileposts are privately owned and may be changed without notice. As a result, this file may not reflect current conditions. Users should contact the appropriate railroad to verify milepost numbers and their locations. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1528364
