I've added a few more STLs today. The photo shows just some of the configurations you can 3D print and assemble. My STLs have interchangeable parts, all you do in pick which parts you want and slide them on a 1mm rod in the order you want. I feel I've covered a good variety of signal types and configurations, did I miss anything? https://www.thingiverse.com/thing:4025702
Very nice! The second one from the right looks like the Milwaukee Road's type with the large hood, cool!
Well, you are missing the old B&O CPL (Color Position Light) signals. Those are similar to the position light signals used by the Pennsy, with 3 yellow lights in a row that is lit either vertical, slanted, or horizontal. That is the one on the right end of your photograph. The B&O CPLs were similar but without the center light of the Pennsy signal head, so those signal heads were smaller. And, the B&O lights were colored, with green foro vertical, yellow for slanted, and red for horizontal. In addition, there was a reverse slanted pair that was "lunar white" and used as a restricting signal. That completes the signal head, but there was more. There could be up to 3 individual white or yellow lights in a horizontal row above the head, and also up to 3 yellow or white lights in a horizontal row below the head. Those were used for speed indications, with the ones directly above the head or to the left of the head being white and those to the right being yellow. Google it for a picture. Interesting note is that the old Pennsy signals have now been converted to CPLs by changing the lenses in the outer circle of lights and removing the center light. But, they still are too big to look like B&O CPLs, and they don't have any of the 6 potential additional individual lights. If you are going to build one, be aware that most CPL signals were not fitted with all possible lights. If I were you, I would build one with all 4 rows for the signal head and one or two of the separate lights in a manner that would allow them to be moved to whatever location was desired for a particular track situation.
