This polyline shapefile depicts the Fixed-Guideway Transit Network, a network database of the nation's fixed-guideway transit systems. Fixed-Guideway refers to public transportation using and occupying either a separate right-of-way or rail for the exclusive use of public transportation or a fixed catenary system useable by other forms of transportation. This polyline shapefile depicts rail transit networks in cities defined as the Federal Transit Administration's (FTA) universe of cities and includes heavy rail, light rail, monorail, cable car, inclined plane and automated guideway. This layer is part of the 2014 National Transportation Atlas Database.The National Transportation Atlas Databases 2014 (NTAD2014) is a set of nationwide geographic datasets of transportation facilities, transportation networks, associated infrastructure and other political and administrative entities. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the re¬lated attribute information for these features. This data supports research, analysis, and decision-making across all transportation modes. It is most useful at the national level, but has major applications at regional, state and local scales throughout the transportation community. The data used to compile NTAD2014 was provided by our partners within the United States Department of Transportation (USDOT) and by other agencies throughout the United States Federal Government. These contributors are the actual data stewards and are ultimately responsible for the maintenance and accuracy of their data. This data is used for national and network analysis applications. This coverage provides users with information about the location and type of fixed-guideway transit and terminal facilities primarily for regional cartographic, spatial and network analysis purposes.
