North American Rail Network Lines

The North American Rail Network (NARN) Rail Lines dataset was created in 2016 and was updated on April 28, 2026 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). The NARN Rail Lines dataset is a database that provides ownership, trackage rights, type, passenger, STRACNET, and geographic reference for North America's railway system at 1:24,000 or better within the United States. The data set covers all 50 States, the District of Columbia, Mexico, and Canada. The RROWNER1–3 fields identify the parties responsible for operation, maintenance, and/or ownership to the railroad. It includes the railroad dispatcher (operational control) identifying the specific railroad entity managing the movement of trains over that segment, the maintenance responsibility identifying who is legally obligated to maintain the rail line, and/or the property owner (land and right-of-way) identifying the entity that owns the underlying land. While many railroads own their right-of-way (ROW) in "fee simple", others operate on land owned by a third party. The same entity may fulfill one or more of these roles on the same line.

北美铁路网络（North American Rail Network, NARN）铁路线路数据集于2016年创建，并于2026年4月28日由美国联邦铁路管理局（Federal Railroad Administration, FRA）完成更新，隶属于美国运输部（U.S. Department of Transportation, USDOT）/美国运输统计局（Bureau of Transportation Statistics, BTS）国家交通地图集数据库（National Transportation Atlas Database, NTAD）。该数据集为北美铁路系统提供权属、铁路线路通行权（trackage rights）、线路类型、客运属性、STRACNET及地理参考信息，美国境内制图精度达到或优于1:24000。数据集覆盖美国全境50个州、哥伦比亚特区，以及墨西哥和加拿大。RROWNER1至RROWNER3字段用于标识负责铁路运营、维护及/或权属的相关方，具体包含三类信息：一是铁路调度员（运营管控方），用于标识负责该区段列车运行管控的具体铁路主体；二是维护责任方，用于标识依法承担铁路线路维护义务的主体；三是产权所有者（土地及通行权方），用于标识对应铁路下方土地的所有权主体。尽管多数铁路以“完全保有所有权（fee simple）”方式拥有其铁路通行权（right-of-way, ROW），但仍有部分铁路运营于第三方所有的土地之上。同一主体可在同一条铁路线上承担一项或多项上述角色。可通过链接https://doi.org/10.21949/1528950获取数据字典或其他属性信息来源文档。
