Anyone got a copy of the circuit or wiring diagrams for a power-on/power-off
point changer? I've got a pretty good idea of how it works, but would like
to see if I'm right. (I know the basics - if the tram is drawing traction
current when the trolley shoe passes through the overhead contacto, the
points are set for the "branch", otherwise they're set for the "straight".
