[Tex/LaTex] Tikz: Drawing an arrow with three lines

tikz-pgf

I'm currently using tikz to draw an arrow with two lines using this style:

doublearrow/.style={draw, color=black!75, draw=black!50, thick, double distance=2pt, ->, >=stealth}}

The documentation does not say if it's possible to have an arrow with three lines. I've seen it in papers before and I guess it is probably also done with Tikz as the arrow tips are the same. Any idea how to do it?

[Converting the OPs comment into an answer]

Found the answer: Draw an arrow path with a double line and at the same place draw a path with one line and voila - "triple" lined arrow. 

triplearrow/.style={
  draw=black!75,
  color=black!75,
  thick,
  double distance=4pt, 
  <-, 
  >=stealth
},
thirdline/.style={
  draw=black!75,
  color=black!75,
  thick,
  <-,
  >=stealth
}
