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?

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}} –  Tobias Apr 11 '11 at 18:23
    
It's a bit buried in the code, but the accepted answer to the following question contains code in TikZ for triple (and quadruple) arrows: tex.stackexchange.com/q/5309/86 –  Loop Space Apr 12 '11 at 18:03
