This is the MARX No. 417 Bell Ringing Crossing signal with Swinging Arms. The lower solenoid rings the bell. there is a solenoid inside the bell that swings the arm. Originally this signal came with track clips that the car wheel ran over to provide the on/off. In this clip the signal is running with a couple of timing relays.
excellent vid, how did you get the wig-wag to move? my 417 do not move electrically
