Falling Rock Detector
The poles and electrical wires at the very edge of the tracks are part of a falling rock detection system. The regular switching and signal lines are behind the detector up farther on the side of the hill. The power lines an poles are still farther up on the hill. Before this system was installed rocks falling on the railroad line were a real problem. Still a bit of a problem but much better now.
Happy Telegraph Tuesday!
