They used Hall Signals ("banjo" signals) in a lot of places.
More modern signals had up to 3 colors in an triangle on each head, yellow and green on the top and red in the center below.

Thanks for the links. I tried google, but I didn't find the info I was looking for.
You may find some info HERE or at The Reading Company Technical & Historical Society. Here's a photo of a Reading disc signal, although they may have used other types, too.
When in doubt, remember that google is your friend - that's how I found the links which I've included.

Does anyone know what type of signals the Reading Railroad used?
Thanks,
