Rob,
The relay I use is from Azatrax. I just happened to have one so I wired it up for my block signal. There are plenty of choices for relays out there, including lower cost than this one (which I think was 20 bucks).
Check out their website as it has some good information.
Smooth operation as the train hits the insulated track piece.
