Derek,

Here is the legend that you may be referring to from the cover of a N&W
track chart in blue print form c.1950's. It is for the various types of rail
used, not ballast.

Subject: Question regarding track diagrams

First let me thank all of you for your wealth of knowledge and the
generosity in sharing it in this forum. 

In N&W track diagrams from the early years, the ones with track layout at
the bottom and curvature above that, there is a line that contains
crosshatching, solid bars, diamonds, or the like. I assume this is to
designate the type of ballast or rail bed construction. 

Is there a legend or standard for such designations and is it standard
throughout the industry or specific to N&W?

Thanks,
Derek Shirley
