how to skip a point along a line that has been divided into equal length segments

[an]

Hi,

I have two zig-zaging offset lines that I divided into equal length
segments.  I want to connect points generated by the division with
lines that are mostly perpendicular to the two offset lines (imagine
making a zig zagging train track).  How do I skip some of the points
where the zig zags occur from the list of points along the rail lines
so that the lines in-between my rail lines are perpendicular to the
rail lines?

Thanks in advance,

An
