in the image is a set of sig's
but what they are for or how they work is unknown to me...
to the left out of shot is a level crossing. both sigs are facing traffic coming from the right of image and are one on each track.
I'm only asking about the top section of the sig the illuminated arms, I know QR has a Y sig like these but in this case the Y is more 1.30 and 3 o'clock and 9 and 10.30 .
what they are for or work please help me as they are in a part of my route and would like to have them in if I can..
