The neither through nor across section, depends on ordering of l and r to differentiate ambiguous cases. An alternative approach to disambiguation is provided in subsection reversed layering.

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.
