They're definitely beautiful signals but I have my heart set on some PRR position signals since that is one part of my freelanced lines will use.
Those Magnetic Flagman Wigwags on the other hand definitely will be in use even though the prototype had already started using your typical crossing signal. May yet try to do a kitbash of the two (as a few were done) but it is the idea of no crossing sign that helps me, since I will be using the wide crossing signs on my signals and on posts.
