A simple type of an overhead electrification.
Thanks to the limited tension compared to electrified:contact_line=catenary and electrified:contact_line=rail, this type of wire is generally used on lower-speed systems such as many tramways, particularly inside built up areas where speeds are lower and also reduces visual noise, as well as some metros.
It's identified by the lack of a messenger write (second wire above the contact wire) as well as the fact that the contact wire is a wire and not rail.
