  Purpose:

  Represents the Ontario Governments initiative to adapt the Federal Governments GEOBASE standard for the National Railway Network (NRWN) geospatial data. It provides enhanced spatial and attribute data for the extent of the railway network in the Province of Ontario, and replaces the existing basic railway-themed data classes in NRVIS/LIO. Although mainly used as a base data feature appearing on cartographic products and views, users will benefit from having additional railway-associated attributes available to them. Additional uses of this dataset include OMNR emergency response and action (e.g. trackside fires), where the reported locations of mileposts and bridges / culverts (water supply) is useful for rapid fire suppression purposes.
