Usage on power features
- power=line + line=busbar - A busbar
- power=line + line=bay - A bay connects an incoming circuit to a busbar assembly.
Usage on rail features
On many railway=* features, this key indicates the name of the railway line in conjunction with branch=*. However, the more widespread tagging convention uses name=* and operator=*. name=* is also a tag for name of object in general so it is a clearly preferable tagging scheme. In some cases it may be necessary to create a route relation with route=railway when the branch, line and railway service have different names.
