Rail Lines and Rail Crossings

Railroad Crossings: The Railroad Grade Crossings dataset was updated on July 13, 2025 and was created on July 15, 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 Railroad Grade Crossings is a spatial file that originates from the National Highway-Rail Crossing Inventory Program. The program is to provide information to the public, Federal, State, and Local governments, as well as the railroad industry for information and the improvements of safety at highway-rail crossings. Some railroad grade crossings were located outside the US or their respective states, and relocated to latitude longitude 0,0. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529075 Railroad Bridges: The Railroad Bridges dataset was compiled on October 14, 2022 from 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). Data subset to the Thrive region in November 2025. A railroad bridge is defined as “Railroad bridge means any structure with a deck, regardless of length, which supports one or more railroad tracks, or any other undergrade structure with an individual span length of 10 feet or more located at such a depth that it is affected by live loads.” based on the Code of Federal Regulations (49 CFR Part 237). The FRA does not have a mandate to inspect railroad bridges: these inspections are required by the owner of the track. The FRA will use this railroad bridge dataset to determine the number of bridges per railroad, state, etc. and will assist in determining priority field activities. Rail Line: This Bureau of Transportation Statistics (BTS) feature layer, utilizing National Geospatial Data Asset (NGDA) data, displays the North American Rail Network (NARN) subset to the Thrive Study Region. Per BTS, "NARN Rail Lines dataset was created...from the Federal Railroad Administration (FRA) and is part of the...National Transportation Atlas Database (NTAD). It is a database that provides ownership, trackage rights, type, passenger, STRACNET, and geographic reference for North America's railway system...within the United States.铁路平交道口（Railroad Crossings）数据集由美国联邦铁路管理局（Federal Railroad Administration, FRA）于2025年7月15日创建，并于2025年7月13日更新，隶属于美国运输部（U.S. Department of Transportation, USDOT）/运输统计局（Bureau of Transportation Statistics, BTS）国家交通地图集数据库（National Transportation Atlas Database, NTAD）。该铁路平交道口空间文件源自全国公路-铁路道口清查计划，该计划旨在向公众、联邦、州及地方政府，以及铁路行业提供信息，以助力提升公路-铁路道口的安全水平。部分位于美国境外或所属州域外的铁路平交道口已被重定位至经纬度(0,0)处。可通过https://doi.org/10.21949/1529075获取数据字典或其他属性信息来源。 铁路桥梁（Railroad Bridges）数据集由美国联邦铁路管理局（FRA）于2022年10月14日汇编完成，隶属于USDOT/BTS国家交通地图集数据库（NTAD），并于2025年11月被筛选至Thrive研究区域范围内。根据《美国联邦法规汇编》（49 CFR Part 237），铁路桥梁的定义为：“任何带有桥面、用于承载一条或多条铁路轨道的结构，无论其长度；或任何单跨长度不小于10英尺、受活荷载影响的下穿结构”。美国联邦铁路管理局并无铁路桥梁的强制检查职责，相关检查由轨道所有者负责执行。该铁路桥梁数据集将用于统计各铁路运营商、各州等的桥梁数量，并协助确定实地优先作业事项。 铁路线路（Rail Line）：该运输统计局（BTS）要素图层采用国家地理空间数据资产（National Geospatial Data Asset, NGDA）数据，展示了筛选至Thrive研究区域的北美铁路网（North American Rail Network, NARN）子集。根据BTS的说明，“NARN铁路线路数据集由美国联邦铁路管理局（FRA）创建，隶属于国家交通地图集数据库（NTAD），是为北美境内美国地区的铁路系统提供所有权、轨道使用权、线路类型、客运情况、STRACNET及地理参考信息的数据库”。
