I use his grade crossing gate circuit.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.
(Modeling Freelance, Eastern US, HO scale, in 1962, with NCE DCC for locomotive control and a stand alone LocoNet for block detection and signals.) http://waynes-trains.com/ at home, and N scale at the Club.
My layout is all Digitrax. I use a BDL168 block detector and DS64 stationary decoder.
If that was the only function involved it would be expensive, but I have other uses for the products as well. The BDL168 can monitor 16 blocks, and each of my 8 DS64s can control 4 switches, so the cost of using one segment of each is minimal.

I have used a Dallee electronics crossing flasher module activated by an NCE BD20 current detector attached to the track feeder that is at the crossing.
I am new to model railroading. I purchased Busch crossing signals(HO 5934) from my local hobby shop.
I am using a DCC controller but plan to run the crossing lights with a separate power unit. Does anyone have any suggestions about the best electronic processor to activate the crossing lights as the train approaches the crossing.
Thanks,
Rick
