GRS "U" Color Position Light Used by the Baltimore and Ohio Railroad, these unique signals always fascinated me. I decided to only use a 12-foot, 4" mast, with no ladders, mainly because I didn't want to set a full foundation and wanted to place the signal close to the garage. I still need to find a 4" pinacle for the top. More (or better) pictures coming soon. Also pics of the "B" relays controlling this guy. My appologies for the large graphic file to the left, but if you wait long enough for the picture to load, you will be rewarded with the aspects changing :-)

Back and Side views. Note that the 'mast' is really two sections of aluminum conduit coupled together. And I really need to replace that blue cap with something better.
