As I read the stuff about double wire, it appears to me that two
distinctly different kinds of double wire are described.

1.  One plus and one negative, same as trolleybus.

2. Both plus, for two directions over single track.  This was common in
early interurbans as it eliminated frogs at passing sidings having
spring switches.  It also gave a second wire as a feeder.  Many early
pictures used it.  The Youngstown & Southern used it up to its last day
of electric operation.
