|Tools for this tag|
route=coach could describe a relation that maps a route of a coach service.
This tag is unofficially used on relations that map the route of a coach service: as of 19 August 2014, there are 48 relations with this tag. Given that this tag is not even a proposal, many coach routes currently use route=bus instead.
OSM wiki is not aware of any formal proposals to move coach routes in the UK from route=bus to this tag. For now, route=bus remains the "tag of best fit" to describe coach routes in the UK until we have a clearer picture.
