Re: grade crossing hook up

["Steve Wise" <swise@aoot.com>]

Hi DrDanDOT (sorry:  dunno your real name):

I assume you're talking a single track?  Getting the crossing gate to come
down when a train approaches from either way?

If you want something simple, an isolated outer rail will do the trick
either way.   Hook one side of the crossing gate to the center rail power,
and the other side to the isolated outside rail.  When a train wheel touches
the isolated outside rail, it completes the circuit (because it closes the
isolated outside rail with the other outside rail making a complete circuit
and firing the crossing gate).

If you want more authenticity, read the article in the jan 2002 edition
O-Gauge Rail-Roading, (Run 184 pages 108-110).  Richard Taylor describes a
way, using relays & rectifiers, to make the crossing gate come down early
enough to be realistic, and the gate goes up quickly after the train passes
through.  And it works both ways.

Hope this helps!

Steve.
