    public interface TieLine
extends Line
    A tie line is an AC line sharing power between two neighbouring regional grids. It is constituted of two [half lines](#half-line). A tie line is created by matching two [dangling lines](#dangling-line) with the same Xnode code. It has line characteristics, with $$R$$ (resp. $$X$$) being the sum of the series resistances (resp. reactances) of the two half lines. $$G1$$ (resp. $$B1$$) is equal to the sum of the first half line's $$G1$$ and $$G2$$ (resp. $$B1$$ and $$B2$$). $$G2$$ (resp. $$B2$$) is equal to the sum of the second half line's $$G1$$ and $$G2$$ (resp. $$B1$$ and $$B2$$).
