  • HO Scale Crossing Signals

    I am looking for crossing signals for my ho Scale layout. I like to have them activated when the light cell is covered when train is passing over. I was looking at the ones by Walthers but from what I read the controller can only activate on one track. I have a dual mainline where I am going to be installing the crossing so I need a controller that can detect 2 tracks but only one set of crossbucks. So in other words I need one I can hook up photo cells on two sets of tracks. I understand that each side would have 4 photo cells in the track. Any suggestions as to how this can be accomplished? I have DCC but figured on the crossing signals working independent.


    Thanks

    I've read literature for crossing signal controllers from Azatrax, Circuitron and Logic Rail Technologies. At W. Springfield, a vendor (whose name I've forgotten) was demonstrating a new speed-sensing control circuit. But I've never installed any. I do own other products from Circuitron and Logic Rail Technologies; they work and both vendors have answered email support question.

      I use the Circuitron circuits for the same reason you describe for your use, along with Tomar as my crossing flashers. And, ITT Products #HQ300 Grade Crossing Bell for my crossing bell. I've been very happy with this set-up with zero problems. However, there are many new products since my layout was built, and I'm sure they make now easy and simple one operating piece units.

        If you are using Photocells for your flasher detection, you could get extra photocells for the second track, and run wires off of the first set of opto sensors. As long as you only have one train on a track at any given time. This won't work if you have two trains on opposite tracks at the same time.

          Circuitron's approach uses one detector module per track, plus one flasher module to drive the lights. Pages 19-29 here:

          Logic Rail Technologies also uses one module per track:

          If your double track is directional (e.g. East on one, West on the other), you might be able to get reasonable behaviour using one circuit for two tracks. But both vendors state you won't get proper bi-directional operation by simply adding sensors to one unit.

              Like Louis, my crossing signals are almost exacting the same as his but I have likely an older version and I need to add a switch to reverse track power for the detection system to work with DCC. Not a big deal, but if it could be done electronically I would be happier.

              Circuitron and Tomar have some excellent products.
