Yep, sad to see the old PRR signals coming down after only 90+ years. I was in the Pittsburgh area last weekend and while driving through Sewickley I met an NS stack train headed North. It was passing under an ex-PRR 4-track signal bridge with position light signals for southbound trains. The 4 heads showed stop (on the track with the stack train on it), clear, clear and approach. What was extra special was that the stop indication was 3 horizontal amber lights, not the 2 red lights (with no center light) that most of the signals became in the 60's. If it wouldn't have caused a major traffic pile up, I would have stopped to take a photo!
