Mixed[edit]

Mixed with standard set (heavy rail)[edit]

The second table half, neither through or across section, depends on ordering of l and r to differentiate ambiguous cases. An alternative approach to disambiguation is provided in subsection reversed layering.

Reversed layering[edit]

The e/x status prefix is replaced in favor of suffix variations in 'x'.

Empty table cells do not necessarily indicate that a corresponding icon is missing. The naming scheme is not bijective. More than one systematic name for the same icon may be found with the rule set, not all of them are used.
