This tag is used to map the track on which the roller coaster's trains run.

How to map

Draw the way of the roller coaster track and add roller_coaster=track.

Railway=* tags should not be used in combination with this tag as it would be a case of Tagging for the renderer.

Bridge=* tags should not be used just because tracks overlap. There should be an actual bridge structure underneath the track.

attraction=roller coaster should not be added to the track.

When multiple tracks are mapped over each other, there should be extra care to make sure the tracks have separate layers and that the order of the layers are correct. When you need to change the layers in advance for a crossing, make sure to set the layers correct well before the overlap.

When the track enters a building or a covered station, the track should be joined with the building and the inner portion of track should be tagged with covered=yes or tunnel=*

For specifying the type of roller coaster track for a specific section, use: roller_coaster:track=*

Note on accuracy of mapping roller coaster track

As you might know arial and satellite imagery are often taken at an angle to the ground that is not 90 degrees. Therefore, objects that are in the air shift relative to their height. Because roller coaster track goes up and down often, the track shifts during the ride. The best way of mapping the track is with radar height information, however this data is not available everywhere. There are some tips to help accurate mapping only with arial or satellite imagery. For example:

• If you know that a roller coaster support is vertical under the track. The track can be shifted onto the concrete foundation of the support.
• If you know that a roller coaster support is equal on both sides the track can be placed in between the concrete foundations of the support.
• If you know there is no bend between the station and the lift hill, the track should be one straight line.

Tags to use in combination

• layer=* – To specify the layer of the way, relative to other sections of track or other objects which pass over/under it.
• height=* – The absolute height from the normal ground level.

Don't use oneway=yes.

Don't use bridge=yes.
