Hi!

Since you make the bar lines transparent for the whole Score context,
I assume you are not using the "Mensurstriche layout" (bar lines that
are drawn between the staves of a system but not through the staves
themselves), like in this picture:
http://lilypond.org/doc/v2.13/Documentation/notation/working-with-ancient-music_002d_002dscenarios-and-solutions#mensurstriche-layout

Then a simple solution would be to replace your
  \override Score.BarLine #'transparent = ##t
(or the equivalent in your \layout block) by
  \set Score.defaultBarType = #"empty"

Of course you can place it in the "movement layout" too

  \layout {
    \context {
      \Score
      defaultBarType = #"empty"
    }
  }

Then the
  \override Score.BarLine #'transparent = ##t
is no more necessary.  :)

If the solution above is not satisfying.

You can use an invisible voice (i.e. containing only invisible rests
or \skip ) for such instructions.
Many people use a variable they call "global" for that.

global = {
  \key d \minor
  \time 4/4
  \override Score.BarLine #'transparent = ##t
  s1*2
  \revert Score.BarLine #'transparent
  \bar "|."
}

music = \relative d' {
  d1 d1
}

\score {
  \new Staff <<
    \global
    \music
  >>
}


Then you can include this \global in every needed Staff .

Cheers,
Xavier
