Rich, Just reading information like this I want you to know I found this information out the hard way a long time ago. With as many questions I have observed lately, this should be very much appreciated by individuals trying to learn about round tables. Some of us are not as advanced in knowledge about O gauge as others. That's why this is such a great web-site.

If you are using MTH DCS then you need an isolated rail where the engine can be added or programmed to the system. So I use my turntable spurs as multiple isolated rails, since the engine is already sitting there. When " MTH Program" mode is switched, all tracks and spurs have power cut-off and only the isolated spur is active. Then I program that spur with that engine. So to quickly add all other engines on the spurs I simply switch the power to that spur via a rotary switch and then set...

One thing that can give a better signal if you have issues with this wiring. Use a pair of relay contacts in place of the switch, Move the actual switch to remotely toggle the relays on. The shorter wire runs from Terminal block to track will make DCS work better. This also lets you use lower power rating switches. The Relay contacts have to carry the heavy juice, the relay coil and switch won't need it. One relay for each siding.

One of the simplicities of Command Control locomotives, is a staging area like this, as long as you have no problem with locomotives sitting on the track, powered, with lights on. I have had good results with my TT/RH wired as one block circuit. Conventional Control is a complete different matter. We attempted something like this with the Club TT/RH using DCS with mixed results. The Track wiring set-up was not as friendly to DCS as it was to TMCC. Both RH's are Korber 304 with one additional...

Wiring new layout with insulated connectors

Bryant Dunivan 111417 ·
I am finishing up the rail laying phase of my project. Total track length is 2,033 inches with 14 switches. My question is: 1) Will I distribute power to center rail from a central point (buss) feeding individually from the buss to various locations for smooth power distribution? 2) Is the power (on/off) to each section controlled by insulators installed on outside rail. Or am I insulating the center rail instead. I did a search for a book that might be really up-to-date, but nothing new...

LED 3 Volt DC Lighting Issues...I'm Stumped & Need Your Help!

Maine Main Line ·
Greetings. I've read as many posts as I could on low voltage lighting and thought I was well prepared for the task at hand, but apparently even my electrical wiring expertise has left me clueless! I purchased some LED 3 volt lampposts to add some nice finishing touches on my layout from a vendor from China on eBay. After having issues just getting replacement light bulbs for my Lionel station platforms, I figured I would go to the much more realistic, and hopefully reliable, LED lighting.

Labeling Wires

I've seen some amazingly tidy and clean wiring on the electrical forums here. The best all seem to utilize color-coded wire (I'm sure there some that weren't, but I can't remember those).

Re: Proto-Sound 3 Powerports?

gunrunnerjohn ·
Do you run conventional or command? Unless you want to attempt to control the markers, I just use track voltage. For the flickering firebox, I buy the LED tea candles from a Dollar Store and remove the flickering LED, cheapest source I've found. They work great for the firebox, gives you the flickering effect for no effort, just a diode, capacitor, and a resistor from track power. You can power the classification LED's the same way. A 1N4003 diode, a 220uf 35V capacitor, and a 1K resistor...

Re: Proto-Sound 3 Powerports?

gunrunnerjohn ·
Well, the short answer is, it's difficult and maybe impossible, depending on the actual installation. That's why I asked. I'm not familiar with the wiring on the PS/3 stuff, but for PS/2, the sound files control the functionality of the various functions, and if they're not in the product, you usually don't have that control. The simple way is to just run them from track power. It may be possible to trigger them from the headlight, but I'm guessing you'd need some electronics as I don't know...

Re: Proto-Sound 3 Powerports?

gunrunnerjohn, I will likely use track power to run the lights. Firebox could go either way, track power or smoke unit power. I need to test the smoke unit power output prior to making a decision. I appreciate your insight.

Re: Proto-Sound 3 Powerports?

gunrunnerjohn ·
I'm sure the 10ma or so of power for the flickering light wouldn't be an issue for the smoke unit power supply. They do change the power to the smoke unit based on the smoke output setting, I think that's a PWM signal, but I've never measured it.

Re: DCS and wiring

Rod Stewart ·
Art; Since no one has jumped in yet, I'll offer a few comments. First, not sure why you want to run DCS in passive mode? DCS and Legacy will play well together, with the Legacy base cabled to the TIU using the MTH cable. Each TIU channel will handle 10 amps or 180 watts of power. This is enough to run several trains on each, or at least two long passenger train with incandescent lighting. You could easily run your lower level on one fixed TIU channel and the upper on the second fixed...

Re: DCS and wiring

Barry Broskowitz ·
Art, While DCS is a lot more tolerant of most wiring schemes than is advertised by MTH, star or home run wiring is almost guaranteed to give you the best possible DCS experience. Your proposed wiring scheme may work just fine, however, if you're building a new layout the absolute best way to go is star wiring. The additional increment in effoft is offset by the fact that you'll know that your DCS signal strength will be maximized if you follow the wiring guidelines in The DCS O Gauge...

My question is this- can I get away with 4 blocks and bus wiring otherwise I would need 12 -14 blocks and a whole lot more complicted wiring? I 'd bet you can. Use a tiu channel for each block, Only one way to find out though... hook up one block, then another etc.

thanks to all for your reply and to Barry your book is an excellent source - glad I have it. The reason for using DCS passive is as follows: I run conventional, Legacy and DCS. The starting voltage is to high for modern can motors but with Legacy or TMCC I can start from zero. In the passsive mode I can overlay DCS signal on any channel. At least this is what I am trying to accomplish. I did not realize that I can set variable to fixed. Would appreciate more info. If not, I am sure it is in...

I use common bus with no problem, with frequent out rail drops and the ground for accessories. I have much larger "loops" than you do, and use one TIU channel for each It's not hard to break up into 3-4 blocks per loop, and gives considerable opertaing benefits. Just run a length of 14-gauge (what I'd recommend on a layout of your size) to each blocks and sever the center rail between blocks. Can motors are not current hogs.

Re: DCS and wiring

One way to solve that issue is to stick a diode string in series with a motor lead in the locomotive. A couple of 6A bridge rectifiers will drop that 5V starting voltage to around 2V and give you the slow start you desire.

Re: DCS and wiring

ARt, if you have a Williams that starts that fast at 5 volts, you are inputting too much voltage to the TIU variable, resulting in a highly deformed AC wave. Cut the input voltage wat down and I think you'll be happy.
