NSW Foundation Spatial Data Framework - Transport - Rail Associated Structures

Various structural elements are associated with the Railway dataset.\r\n\r\nThe following are ‘crossings’ being a point feature class representing structures that facilitate the crossing of a road or railway over, under or through another feature.\r\n\r\nRail Bridge: a structure erected over a depression or obstacle to carry a railway.\r\n\r\nRail Tunnel: an underground or underwater railway passage.\r\n\r\nRail Culvert; a masonry conduit which serves as a channel-crossing for water or a transport network beneath a railway.\r\n\r\nNote the ‘ontype’ attributes of railway features which have an obvious topological link to these features.
