Re: Complete beginner in DCC

I used DC/analogue when I had an OO layout, but when I replaced it with an N-gauge layout I converted to DCC. In my view DCC makes building the layout so much simpler than DC because you don't have to think about having separate isolated and switched sections to run more than one loco at a time; All...

Re: N gauge control

I think the complexity of your layout, and how you want to run it, is a greater factor than gauge when deciding whether to go DCC or analogue. I use Lenz DCC on my N-gauge layout. The advantages of DCC are simpler wiring of the layout -- no isolated sections are needed for running more than one loco...

Re: N Gauge Controllers

The insulated isolating rail joiners are just like the regular metal ones, except they're made out of plastic (nylon?) and have a spacer built into them so that the ends of the rails can't quite touch each other. You can see three of them still attached to their sprue here https://www.track-shack.co...

Re: N Gauge Controllers

Even if you have only one loco now, I would recommend that you insert isolating rail joiners at the start of each siding. For the moment you can simply connect them all to the main power feed without switches, so that they're all live all the time, but it then makes it simple to make them switchable...

Re: N Gauge Controllers

Although I use DCC on my N-gauge layout, I have to agree that for your layout analogue (DC) is quite sufficient. And, yes, you only need one controller if you only wish to run one loco at a time. But if you're going to have other locos sitting in the sidings, you'll have to have switches to isolate ...

Re: Soldering

Despite having a good soldering iron with a fair selection of tip sizes, I've always found it very difficult to solder direct to an N-gauge rail without damaging the plastic bits. So on my present layout I copped out and soldered a dropper to every rail joiner, and soldered the droppers to a 'ring m...

Re: Servo control

I built a whole bunch of servo controllers using PICAXE 08M microprocessors. They have switched outputs via transistors for LED route indicators, plus solid-state relays for frog-switching. Cost was about £9 each, plus cheap Hobbyking servos as mentioned above.

Re: Droppers

I use the individual wires stripped out of twin-and-earth 15A electric cable for my "ring main" feed around the layout. For support it passes through terminal blocks screwed to the underside of the table, and I cut gaps in the insulation wherever I want to solder a dropper wire to it.

Re: PECO Code 75 Double Slip Wiring

I had trouble with my single slips until I saw the diagram, like in Flashbang's link, that explained that the switch on one point motor switches the power to the other frog, and vice versa. After a bit of time with the diagram and some coloured pencils it all made sense :idea:

Re: Peco N-Gauge Code 55 Point Wiring Help Needed

With N-gauge you have to solder your own feeder wire onto the short link wire that's underneath. I don't understand why they don't supply it from the factory with an extension already attached, like they do with the 00-gauge ones.

Re: thinking of going dcc

Thanks all for the food for thought,as you have said Bufferstop its the rewire of track and updating my collection with decoders that is putting me off ...... Another vote here for DCC. So long as your existing wiring is solid (good connections and regular track feeds) there's no need for any re-wi...

Re: Why have my green LEDs turned yellow?

Update: It's just dawned on me what went wrong: I was connecting my monitoring circuits to the + and - of each LED to detect its state, but my monitoring circuits share a common 0v ground with the points drivers circuits, and what I was effectively doing was bypassing the 10mA LED drivers so that e...

Re: Suitability or not for DCC

There certainly are decoders small enough to install in N-gauge locos but, taking Lenz as an example (because that's what I use), their "mini" series, which are suitable for N-gauge, can only handle half the current that their regular series can. So mini decoders might not be man-enough fo...

Re: Why have my green LEDs turned yellow?

The idea is simple, but implementing it is proving problematic. An optocoupler in parallel with each LED might be an answer, but the ones I've looked at draw more current than the LEDs, and I don't really want to have to add any more components. Diodes to block any unwanted currents (if that's the s...
