I'm really confused about Lionel 6-22931 Cantilever Signal. Not how to hook it up, that's easy.
I'm confused at the number of red and green lights and at the odd positions on the pole.
TOP: Red - Red - Green BOTTOM: Red Green.
If this was to be used over two or three lines of track, I could understand it, maybe.
But Lionel's directions show it being used over only one line of track.
Why not just a simple red and green light to show the track is clear or not, like the old Lionel 153 block signals.
Why so many lights on the new one?
And does this Cantilever Signal actually exist on a current railroad?
Thanx.
