Asked this question way back in the Bethlehem Branch thread and got no answer, so I'm hoping someone can fill me in.
This pic was taken a few years back in Bethlehem before the tracks were ripped up. Those crossings along that stretch through the city were the first crossings I have ever come in contact with that had lights like the one pictured here. What was the deal with these additional signals? Was this a Company wide standard crossing installation on The Reading, or were these here due to close clearances between the roads and the crossings?
Also, what did they do upon activation? Were they A: both solidly on; B: both lights flashing in unison with the "normal" flashers, or C: top and bottom lights flashing alternately with the normal flashers?
Now for the true long shot.....any video anywhere of one of these things in action?
