> I need two black lines with /transparency/ in between.

try the offset or coffset setting within the vlines instruction:

       offset  (experimental) - offset for the vectors lines in pixels for plotting parallel
       lines in distance equal to offset (accepts  positive  or  negative  decimal  points).
       Useful to print streets with several parallel lanes;

       coffset  (experimental) - offset for the vectors lines. If coffset is used then  off-
       set of line is equal to coffset * category value and offset is used in legend;

(I think that "pixels" should really say "points", but..)
