    Does anybody have a diagram of Southern Railway signal aspects? I have a a cantilever bridge kit appropriate for the Southern, but I don’t know what signals to put on it. From what I know, it would be a 3-over-3 or 3-over-2 signal head arrangement. Where would signal bridges be used as opposed to upright/standalone signals? Sidings?

    Here're two photos I shot that show the same signal positions on both types of bridges. I'm thinking that these are intermediate signal bridges and both are on double track mains. The top photos is from October 2016 at Lowell NC and the other from April 1988 at Cornelia, GA.

    I found a blog post on The Position Light that features Southern signals proper. My problem right now is trying to figure out what the physical hardware looks like that displays those aspects. I think your photos are pretty standard Southern equipment, and the fact that they both have the same signal heads lends them some credibility as to what the rest of the system looked like. The Norfolk Southern signals in some locations look like modernized versions but operating on the same principles. Since I am not installing this at any location on a layout, I am working backwards to determine the signals and then the track arrangement they would work for. I guess I am just looking for prototype photos to understand what the cantilever bridge is used for.
