|Tools for this tag|
The tag usage=tourism is used together with railway=* to map a tourist rail line: railway tracks for tourists, around museums, historic or "heritage" trains, often only on weekends and holidays and/or seasonally. Most often used with railway=preserved, or railway:preserved=yes + railway=rail or railway=narrow_gauge.
|A track is either tagged with usage=tourism or with service=*, not with both.|
Use usage=* only for the main tracks (not for siding, yard tracks etc.). That also applies for crossover or overtaking tracks.
Other values of usage=*:
|usage=main||Main line, presumably heavy traffic, often double tracked and/or electrified, may be high speed.|
|usage=branch||Branch line, less traffic and lower speed than main lines, often single tracked and/or not electrified, may be constructed to lower specifications than main line. May connect a place to a mainline or serve to connect mainlines, typically a few dozen miles in length.|
|usage=industrial||Tracks in private use that serve only freight transport inside ports, industrial complexes or mining areas, and for connecting these to the public network|
|usage=military||Tracks for military use, mainly on military areas, munitions storage areas or connections to the public railroad network.|
|usage=test||Tracks used for testing of new vehicles or new rail transport technologies.|
