Re: Staging yard wiring question
开云体育Scott For me, a bus(or sub-bus) connects many feeder wires as one electrical component; feeder wires run from the bus to individual rail segments.? Feeders always have one end attached to a rail.? In this implementation, a main bus feeds the sub-busses, one for each track in the yard; each one is relay-switched, and current-detected for occupancy.? The other rail in each track segment is returned to the main bus uninterrupted. If my sub-bus is your feeder, what do you call the wire running
from the feeder to the rail?? I've heard the term 'dropper' used,
but always thought that was just another term for 'feeder'. Blair On 6/21/2021 6:00 PM, Scott H. Haycock

Re: 1156 Bulb Short Protection and Powercab
And I'm with John. Until a good solution comes along - but I also want a reasonable price. You can't compare a bulb with a good circuit breaker. But. The price must be within my budget. And that bulb certainly does it's job and for what it cost - wow! I also think it is best on a small/ish layout where you can see the bulb. A buzzer wired in could be even better. But then, the cost goes up. I must admit, it's a good thing that NCE has that feature.? ? ? ? Morgan Bilbo, slightly over one year with very basic DCC

My question was focused on the best wiring of the second, common, rail.Hi Blair, In my opinion, there can never be too many feeders to any rail. It may seem like a lot more work on paper, but I have found, once you get the rhythm going, it is no big deal. On my layout I have a minimum, of one feeder per section, regardless of size, and one feeder every two feet, for both rails. Peace, Mike G. |

Re: Staging yard wiring question
开云体育Why is it that no one reads the original post any more?? As I said, there is a relay, and a block detector, for one rail of each track.? My question was focused on the best wiring of the second, common, rail. Blair

Re: Staging yard wiring question

I did this exact thing for the exactly the same reason.? In doing so, it prevents the command station from seeing a surge in voltage and therefore, a total power shut down.
To make the routing of power to a specific track as simple as possible, I use two, 12-position rotary switches, skipping every other contact so I am never more than one click away from shutting off the power to that track (each rotary switch controls the power
to 6 individual tracks).? I also placed a power reading LED neatly between the ties to confirm a "visual" when power was on.? But this feature is no longer needed because all 12 tracks hold "favorite" trains with lighted interiors, along with their startup
of sound.? You immediately know what track you've selected . . . .

One reason to have each track separately wired would be to prevent all the sound equipped engines in the yard from starting up at the same time when you power up!

Re: Staging yard wiring question
that was covered by the fact that I'm wiring one rail individually, and switching them when selected.? (i.e. when a turnout is aligned for a track, at either end, the track is energized).

Re: Staging yard wiring question
thanks, Steve, for the sanity check.? That's what I thought, but...? So the only reason I might run separate runs is if I want to provide the flexibility to split the yard across two boosters at some point in the future.

Re: Auto Reverser (s)
开云体育Maybe swap in a different AR1?? It's possible the relay contacts
are welded in the unit, and it's unable to properly switch
states.? Or, the circuit is fried completely, and unable to
energize the relay.? I threw out one last year, as it failed to
operate at all even when swapped into a location where another one
had been working fine. Blair On 6/21/2021 3:00 PM, BillMellott

anything?

I know for me.. and the HMRC (Housatonic Model Railway Club)
layout.. I had a great many AR's in PSX-1 districts - without a problem... and
without me having fully read instructions on the PSX-1 or AR's in use layout
(many different AR Mfg's)
Everything worked great.. till one day we finally got to using the
Wye in one Yard.. and the Wye would not work correctly.
Long story short I had to adjust the CV setting in the PSX-1 for
longer delay for the AR to trigger correctly.

Staging yard wiring question
I have a 12-track staging yard; in order to implement detection, I need to run one bus wire for each track's front rail, having run that wire through both an on/off switch and a current detector. All is fine there.? However, respecting the second bus wire for each track back rail, is there anything that prevents that wire being common to several/all of the tracks?? I.e. could I wire, in the extreme, all 12 back rails to one common bus feed?? I had already assumed I'd run a wire for each track, but it occurs to me that that may be excessive.

Re: 1156 Bulb Short Protection and Powercab
John Bauchiero
开云体育I have to agree with Morgan. I do run NCE but the 1156 did not work for me. I use the 1157’s brake filament. One filament of the 1157 ?is equivalent to the 1156 and the second is a higher current. The 1156 would not light on a short but worse, it would warm up and not pass enough current to the existing locos. I got brave and tried the 1156s in parallel without total satisfaction. So when using the high current 1157 element it worked well and the PowerCab did not trip. It lit on a short but I am not one to leave a short condition for a long time. ?I’m a gambler but not to a point to risk my rolling stock. ?I am sure if the current was slightly higher and more instantaneous, the PowerCab would go into protect mode.?This doesn’t mean this is the best way to protect the PowerCab but until I install a real protector, it will have to do. I am tending to lean toward the DCC Specialties PSX breakers. Flexible, functional and future DCC worthy. I would welcome comments or corrections.?

Re: 1156 Bulb Short Protection and Powercab
Just for those of y'all that don't use NCE. I use a 1157 bulb with my Digitrax and it works like it's supposed to. I mounted it at the center of my layout/command station, visible all long my shelf layout. And it has functioned perfectly. No matter where I stand, if I see it flash or light up. I know instantly where the problem is. And it's usually right where I'm at. LOL
