    Default inside of a crossing bell

    Well I found this really interesting. The video has a shot of the inside of a Mechanical Crossing Bell at work. I never knew how they worked...

    Default RE: inside of a crossing bell

    Yes, neato! 12VDC, electromagnets, and a hammer. Well, 12VDC ideally, what the real voltage might be is variable. The voltage also effects how fast the electromagnets are drawn and concequently, how fast/hard the hammer hits the bell.

    In this video, (in the middle) you can see my 50+ yeard old WRRS bell at work from front and rear.
