Ontario Railway Network (ORWN) - Marker Post Coordinate system: 4269 - "NAD83" Abstract: This data set is a point coverage that can be used to identify the location of a sign indicating the distance along the rail network. For example, signs are often posted at intervals along a railway subdivision indicating the distance from its point of origin in miles or kilometres. This layer is part of the Ontario Railway Network (ORWN) suite of 7 Data Classes that have been adapted from Natural Resources Canada GEOBASE National Railway Network (NRWN) standards. The other features are available on the GeoPortal and can be located by searching the following titles: Ontario Railway Network (ORWN) - Crossing Ontario Railway Network (ORWN) - Junction Ontario Railway Network (ORWN) - Station Ontario Railway Network (ORWN) - Structure Line Ontario Railway Network (ORWN) - Structure Point Ontario Railway Network (ORWN) - Track Please refer to the ORWN User Guide for additional information about the use and context of information stored in this layer.

  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.
