Here is how mine work. The track block extends past the crossing in both directions. I have single and two track grade crossings, just add another Dallee board in parallel if the tracks are in separate power districts. Simple to install and no adjustments needed.

Gregc, that is what I posted above. I think the issue is the Dallee #365 is $45. Add to that the crossbuck or gate arm set, plus in HO the sound is separate so it adds up to $130. I have gate arms on each side of the road approaching the crossing so that adds another $76. Not cheap but it works flawlessly with just the connection of a few wires.
