Camden,

The following will produce a single line with tie marks.  Not a
double-parallel line, but it might get you started anyway.

In layer definition:
   CLASS
     NAME 'Active Line'
     EXPRESSION /Active/
     STYLE
       SYMBOL 'circle'
       COLOR 0 0 0
       SIZE 1
     END
     OVERLAYSYMBOL 'fence'
     OVERLAYCOLOR 0 0 0
     OVERLAYSIZE 7
   END

In my symbols.sym file:
   SYMBOL #12
     NAME "fence"
     TYPE TRUETYPE
     FONT "arial"
     CHARACTER "I"
     GAP 10
   END
