KRW crossover components

Identical topology… ABZ looks good KRW looks better …different geometry ABZ good, smooth KRW bad!, crooked

KRW (from the Dutch kruiswissel; literally cross exchange) icons are for crossing between parallel lines, and should not be confused with ABZ icons used for branching off from a line. See WP:RDT/BSicon-KRW for single curve (non-junction) icons.
