This can be used to - throw a turnout - change a signals state - chante the state of a relay - show "occupied" on a s88; thus either telling a computer that a train is present, or a "memory unit", or others. You should look in the signal book to learn more; at least the old one describes the traditional uses of contact and circuit tracks.

There are also 24194 and 24294 curved circuit tracks that work the same. All are activated by a slider.

Any advice here? /Ulf Quote: [size=1" face="Verdana" id="quote]quote:Originally posted by McLae <br />If you look at my article "Simple block control" on the home page, the empty blue, yellow and red squares are 24X94 sections.

The magnets need to be at the correct height: too low and they snag on pukos, too high and the switch ignores the magnet. My .02$: If you are just starting, get a few circuit tracks and experiment. After you get an idea of how the train control works, you can switch to reed switches. I have a pair of LDT ocupancy detector modules waiting for testing.[:I] I will probably wind up using these with RR&Co Software to automate my main layout.

You have a transmitter in the Lok (more soldering[xx(]) and recievers that detect the signal, Lok X just passed dectector Y. I remember (Many moons ago) seeing pictures of how someone had set up IR detectors for train control on his DC layout. Lots of hard work to wind up with the same information that a circuit track can give you. If you have lots of money, and not many Loks (something wrong with that idea[}:)]) Lissy could be a viable option.

It provides a point source of train location. It is, however, a lot of work. I did a description of it some time ago. It can be found at: http://www.sem-co.com/~r.../trains/irifc/irifc.html I had originally planned to do all my detection with this system, but I've gotten lazy and I now use contact tracks where space is not a problem.

Yes, Lissy is doing the work, and very much more. Therefore, it's expensive too. Lissy is operating in a digital environment only, and also needs a central with LocoNet, like IB, Daisy, Digitrax, (Piko, Fleischmann). It indicates presence and direction, just as the circuit tracks, but in addition also - allows for identification - what train is there? - speed measurement - triggering actions in the digital system, with or without computer. Actions may be throwing turnouts and the like, or commands to the loco like slowing down, pull the whistle or whatever. In my view there is no relationsship between Lissy and mfx, except they are both present in the digital field. /Lars

Joined: 12/05/2005(UTC) Posts: 1,908 Location: Stockholm, Sweden		ok, now I've bought 3 of these circuit tracks. How do I connect them to my motorized swithces??? I assume the yellow goes to the feeder I have for lights etc. Do I connect the 2 blue cables to the switche's blue cables? TIA,Ulf

(On the side the train is comming from. I always get it wrong[:p]) Pretend your finger is a Lok slider. As you run your finger over the track, the first blue wire you encounter will be grounded as your finger passes. Same as pushing a button on the control pannel. Connect that blue wire to whatever you want to activate with that train, switch, signal, etc.

Joined: 12/05/2005(UTC) Posts: 1,908 Location: Stockholm, Sweden		I've tried circuit tracks and switches now, to no avail. the track works. I tested it with a 12v lamp. and the switch motors also work The circuit track seem to just send a short pulse. Not enough to throw a switch... What else might I need? TIA, Ulf

If you are using an MS, power the switches (yellow) from the Red (puko) wire. If I have the MS power understood, the MS red and brown are not the same as yellow and brown from the trafo.[B)] In the old system (6021, IB), brown was track, and was common. With MS, brown to track is NOT the same as brown from trafo. If you feed Yellow from trafo, brown from track (circuit track) will not work. Hope this helps.

Joined: 12/05/2005(UTC) Posts: 1,908 Location: Stockholm, Sweden		I have MS to power my system. The switch motors (and lamps) are powered by a second trafo (as the booklet describes). Could it be that I need the circuit tracks to send a pulse to a signal, which in turn can throw the switch? Or can the track itself throw a switch? /confused...

Connecting the extra transformers brown to the rails as well (common ground). Or, 2. Turn the circuit track. From factory the switch is connect by a cable shoe to the track; this may be removed. Instead connect that short cable to the brown of the extra transformer. This save expensive digital power. /Lars

However, If he is using an MS, he cannot be running many loks anyway. The small occasional switch power usage will probably not cause problems. Good trick for later. Meantime, happy to help![:I]
