Signal question

[NW Modeling List]

Mark,
Here are a couple of photographs of the 1930's era signals on the Bristol Line.

I haven't yet found anywhere on the Bristol Line that had a position light signal before the line was converted to CTC and signaled with position lights throughout in 1946-47.  But, the Clinch Valley, New River Valley or Christiansburg Districts may have had some of both.  I know the N&W had a few PL locations in that era, but don't know where exactly.

I'm JUST getting to the signals part of my 1930's era layout, and have
been looking for the drawing of the Block Signal, especially, the height of the
signal heads above the rail. I'm doing a generic Southwestern Virginia look
about 1934-1938.  It's a two track all the way around with just a few
sidings, all manual.  I have several sets of single track crossover, some right
to left some left to right.  I will most likely use a rotary switch for the
lights, but didn't they use both Semaphores and Block signals together?  As
you can see, signals are my weak area.
