As a precocious 5 year old, I could not figure out what caused these crossing signals to activate near my grandparent's home in Lewistown, Pennsylvania. http://maps.google.com/maps?f=q&source= ... 02932&z=19>.
My grandfather said the weight of the train squeezed the juice (electricity) out of the rails which turned on the signals.
So I began piling ballast rocks on the rail and then stood on it.
Nothing happened.
Years later, I discovered paper(?) between two rails and their joint plates and thoughthere must be electricity running through the rails.
But would that not be dangerous or shorted out by water?
Visiting my grandmother on Easter Day I went exploring the tracks near the depot on that same branch line.
A long bare metal cable connecting rails was lose enough that I was able to wedge it in the opposite rail joint.
THE SIGNALS ACTIVATED!
No bells, but the crossing signal control box light illuminated and I could hear the relays inside snapping back and fourth.
There was no traffic, otherwise I would have not done this little stunt.
Immediately I left the area, expecting someone from the railroad to come and un jam the wire.
An hour later I returned to the scene of the crime and the signals were still operating.
Wanting not to look suspicious, I walked down the middle of the track and "accidentally" caught the cable with my foot and the signals turned off as I innocently continued home.
Now I knew how the signals worked.
