I have some concerns about the size of the wires between the turn out and the hand controller. My track power comes from the Lionel Brick which maintains a constant 18 volts on the track. Are my concerns real.
Thanks,

Hi David,
Your concerns are real, but unfounded. The switch operates on low voltage DC. The AC is converted internally. The voltage actually traveling to the switch controller is +5vDC and a -5vDC to light the colored LED indicator lamps via the yellow wire.
The switching motor power (a small DC motor) is controlled by the board. The board controller is switched by the red, green and black wires. The controller lever only changes which circuit on the board is activated by mechanically momentarily contacting the green/black and red/black.
Finally, there is only milliamps of current flowing, which would be what one would have concerns about when considering wire size.
Yes, there is 18vAC on the track at 10amp potential on the track. The internal switch boards are designed to handle that and convert it to only the small DC power that is needed.
They do not require anything close to the amperage required by coil motored turnouts(switches)

What Carl said. 
Fastrack switches only have a small DC motor to activate the switch, they draw less than 100ma maximum during the switch operation, even less at other times. Since I run command pretty exclusively, I run the switches from track power to minimize the wiring issues. I use the command Fastrack switches, that way I don't really have to wire extra control wires either, just plug them in and go.

Thank you for your time and answer. I do have another question regarding the switches, I need to extend the wires from the switch to the controller about 15 feet, would I use the same gauge wires or go larger.
Thanks, Dave

Gunrunnerjohn,
Thank you for your time and answer.
Take care, Dave
Another related question, if I want to bury the wires below the platform, when disconnecting the wires is it preferable to disconnect from the switch or from the remote controller. Thanks
I cut mine, soldered the joints, heat shrink the individual wires back together and taped back in a bundle. I have done this on 4 of my fast track switches with no problems
It is much easier to disconnect the wires from the switch. I extend the wires with 4 conductor phone cable using terminal strips in between. I have short pigtails of phone wire with a phone connector on each switch and use a double female phone coupler to connect to the extension wire. If the switch needs to come out I can just unplug it under the layout. The phone cable wire colors match the controller wire to make it simpler.
Gentlemen,
Both Carl and Guns advise is absolutely true, I run my FasTrack Command Control switches off Track power as many as 99 of them. Low Voltage Switches, AC covered to DC at the switch, and it works like a dream. No need to worry about the Lionel wiring and you can run them in tandem if you like. IMO these low voltage FTCC Switches are one of Lionel greatest modern engineering accomplishments, and they can be controlled from either the Legacy Cab2 or the TMCC Cab1. A world class piece of engineering, wireless Lionel Command Control Switches in reality have no equals on the market today. Now if the foreign builders would just quit playing games with Lionel's engineering and supply the correct parts and test every FTCC Switch before it's shipped, all the switches would work perfectly when purchased.

The Construction on the new Donovan's Reef Bar layout, is progressing and all the FTCC Switches work perfectly, with more to come on the lower level which will feature our 18' Bar as a Big Train Tunnel.

John H,
I like your way of wiring and will use your method in the future, simple and easy
Thanks, Dave
I also have used a flat 4 conductor phone cable to replace the cable between the switch and the remote, to provide some additional length. I'm not sure what the wire gauge is for each of the individual wires, but they are quite small. Works perfect for me with no issues controlling the switch.
It helps to "tin" the wire leads with some solder before making the connections to the switch and the remote... to ensure a solid connection.

GRJ,
Do you run DCS as well as Legacy on your layout ? Reason I ask is I always understood that when running DCS it is recommended to power the Fastrack switches with accessory/external power and not track power ? 
Well, I use a little trick for mine. Yes, I have DCS, and so I use a 22uh choke to jumper the power to the switch power input instead of the jumper that Lionel supplies. DCS issues all fixed!

I believe that you received the info that needed. I saw those replies before I could respond.
The flat in the matching colors is easier to find than the old 4 wire phone cable. Most phone cable today is Cat5 cable, which works. It is just a little small in gauge and one has to be careful stripping it. It also doesn't tolerate a lot of bending. Something in a 20awg handles easier.
Carl,
Thank you for that info

I run DCS and I have not heard that before, using accessory/external power. What is the reason for that

One would assume that it is to avoid the DCS signal interference created by the control electronics in the FasTrack switch. I am not sure that a separate power source would help. The center rail would still be connected to the rest of the track.
Using the 22uh choke on the track power terminals is the solution. MTH RealTrax switches use coil motors to avoid the signal interference.
This is where I saw the original post about not using track power to power FT Switches when using DCS (and GRJ's RF choke suggestion) and I'm sure there have been other posts as well.
Try powering the FasTrack switches on track power.
That's a very bad idea when operating in a DCS environment.

Barry, has anyone ever tried adding RF chokes to the Fastrack switches to eliminate this issue? Just wondering if you've ever heard of a fix. With the command switches, it's very handy to just plop them into the layout and not have to wire anything, that's the reason I ask.
Nothing is so easy as the job you imagine someone else doing.
John,
Running the DCS signal through a magnet coil or the coil of a motor is a different source of interference than that caused by a CV board. I don't know if an RF choke would nullify that particular form of interference.

I guess it just has to be tested. However, Fastrack switches have a very small DC motor to activate the switch tracks, so there are no "magnet coils". If you can run a locomotive around with a motor, it would seem these would be similar.

I like the idea of track power, but I suspect adding a choke may be necessary to solve the DCS compatibility issues. Note that many Legacy and even some TMCC locomotives require an RF choke to avoid interference with DCS locomotives. I suspect Barry's comment is based on experience with folks having issues with them on track power, so something would probably have to be done.
Gentlemen,
I will let you know if I have any problems with my FTCC Switches on the larger layout, in the new Train Room/Bar. So far absolutely none. Switches powered from track power and controlled from the Legacy HHRC. Right now I only have about 10 switches in use, probably about 15 more will be added as we continue building the multi-level layout. Actually I do not look for any FTCC Switch problems. I do recommend running Legacy drops from the opposite outside Rail of the DCS connections, for some reason it helps when it comes to FTCC Switch operations.
PCRR/Dave
Can I put two Fastrack switches back to back with center rail jumpers removed on all 4 open ends? I am using auxiliary power on both. I have a friend with learning disabilities and he cannot operate the handhelds. He was using DCS / TIU and wants to go conventional all the way. I have removed the TIU and added switched block sidings but am not sure how to carry track power through the turnouts. (I may not have posted this in right place, but did not see a place to start a new topic, so if I need to move this post, please let me know.)
