Talk:OpenRailwayMap/Tagging in Canada
Tagging of name
For the name, I would follow our counterparts in the USA, and only add the Primary Operator/Owner of the trackage when there are subdivisions with the same name and there is a need to distinguish between both of them.
That is how I have been doing rail tagging, and is what seems to be the global and North American consensus
Please do not prefix subdivision names with the operator unless a nearby identically-named subdivision benefits from disambiguation by doing so. For example, there are two "Dallas Subdivision" relations in Texas, but because of their proximity and ease with which they may be confused, one is named "UP Dallas Subdivision" and the other is named "KCS Dallas Subdivision." (Good practice has also properly set operator=* on both). Otherwise, continue to migrate the operator (e.g. UP, BNSF, CSX, NS...) to the operator=* tag, removing it from the name=* tag unless the above "proximity exception" exists, then prefix the name=* tag with an operator abbreviation as in that example.
