Drawings of N&W Cantilever Bridge (Signals)

[NW Modeling List]

Mark,

Somewhere in the Pennsy library that I sent a link to, there is heights and dimensions.  Not sure where but I remember seeing them when I was looking for something else.  Pennsy and N&W used alot of the same dimensions.  You might get a good idea of heights and measurements from the library.
