Re: DCC loco acting up

Doug Stuard <dstuard@...>
 

I assume wheels, wipers and contact strips are all clean and
touching what they are supposed to touch.

Does the DCC loco work OK on DC (assuming the option is enabled in
the decoder, which most are out of the box)?

Have speed step settings been checked? If the command station
assumes 14 steps while the decoder expects 28/128, funky things can
happen.

I am using ATLAS code 100 track with PECO turnouts.
I need to install a crossing track. ATLAS sells many
sizes with different angles. PECO only sells 2 sizes
but they are listed as insulfrog. The ATLAS crossings
do not say whether they are insulfrog. I would prefer
the PECO since they dont require any special wiring.
Would the ATLAS crossovers need special wiring to be
DCC freindly ?

Not an On30 Porter, but just put one in an HO Porter... Had to use
the smallest NCE they make with wires, then route the decoder into
the cab area and slide it ontop between the boiler and roof.

Re: Reverse/Return Loops

Blair & Rasa
 

Hi Ray
Okay. This is much easier.
As for reversing/return loops, I was asking whether you were trying to
define a "difference" between them that you saw; no problem.

Yes, viewed from one perspective, you have three sections that will need
reversing. However, you could serve the purpose with one reverser, two, or
three. Segments DG, DB, and CH could all be isolated and wired to the same
reversing control - caveat - this depends upon not entering both sections GF
and HC simultaneously, thus demanding two polarity swaps simultaneously.
Since you say you want to use these as meet/passing sidings, I think this
is a bad idea. Two reversers, one feeding GFD and BXFD and the other
serving HXC, would be much better; this also resolves the polarity issues
around the crossing at X nicely.

However, as another poster pointed out, you could achieve the same result by
isolating segment CDE (effectively, the whole track segment bounded by the
switches themselves - just connect all rail to the mess with plastic
joiners). What this does is give you a segment that reverses it's polarity
regardless of whether you are entering or exiting it, to align with the
polarity of the adjoining segment. I suppose to cover the X polarity
issues, you could extend this reversing section out through X to near-H.

Since the switches are close together physically, and functionally
interdependent, this would work well. However, long consists of lighted
passenger cars, multiple unit lashups, etc. may present a problem, as you
need to ensure that your reversing section is long enough to hold the
complete lashup. If those are not in your future, go for it.

I'm sure others will chip in further amplifications/corrections.

Reverse/Return Loops

Ray Freeman <rayfreeman3@...>
 

OK, once more into the breach.

I've posted a labelled partial track plan to the group site. A thru H are turnouts and X is a crossing.
Everything is on one level. What is a reasonable way to handle the reversing polarity issues
on the return loops (as opposed to reversing(?) loops)? I am aiming at DCC control for the locos, and a
mixture of manual and standard electrical throw turnouts (no DCC turnout control or block signals
anticipated at this time). I have a Tony's TE PSRev on order.

The term "return loop" was coined, on this board, by Marcus Ammann. You can call it anything you want,
I just want to know how to get this thing to work electrically before I dive into laying out wiring.

As you can see, there are a number of interlinked reversing loops here so I am anticipating having some
polarity problems to overcome. Am I underestimating or overestimating the problem?

ABE and AE are planned to work as passing tracks. So are HCD and HGFD.

Caveats: This is my first layout. I have severe space constraints. There will be a maximum of two operators
because there's no place a third can possibly stand.

Any advice on how to proceed would be appreciated.

Ray

Re: Atlas Code 80 Turnouts

The switch shown on my diagrams which are linked to the turnout's
throwbar, may be part of a switch machine solenoid. This is true on
NJ International solenoids which have three such switches on their
mechanism. Tortoise has two of them.

Code 83 is used by Atlas for HO scale. N scale uses Code 80.

The Atlas C80 N scale turnouts have insulated frogs (similar to Peco
Insulfrog) and are DCC friendly.

Re: RETURN LOOPS

Mark Gurries
 

If you have illuminated cars you will have to consider a more complex
solution because when the lit car spans the dead section, you'll have
double the voltage across the bulb and it will probably blow out.
I going to have to disagree with Earl on this one...

Voltage doubling can only occure under very secial circumstances that
involves incomplete or improper wiring AND there is more than one
booster involved.

-->>>It can NEVER happen if your multiple boosters all share a common
(ground) or Home ground connection between them as recomended by ALL DCC
manufacutures that support multiple boosters.

-->>>It can NEVER happen if you only have one booster.


This layout will only need on booster and a single PSREV. Earl is
correct about plastic wheels ( I hate them) in helping you operate
trains without concern about lenth relative to the reversing section.

Earl is also right about lighted passenger cars but ONLY in terms that
there will be a problem. A short circuit will occur BUT there will not
be ANY voltage doubling.

I really got confused on that. The bulb will experience zero voltage and will just go dark until both trucks cross the insulating gap.

Ray,

I have something close to yours but with only one section crossing
back onto it's self instead of three. Which is the section that I
added an AR1 and it works just fine! I believe that Loy's Toys
carrys a unit that will handle 4 return loops and includes circuit
breaker protection.

Re: RETURN LOOPS

Earl T. Hackett <hackete1@...>
 

I made a slight edit to your track plan. Any train that will be reversed must pass through the red section. Using a reversing booster on that section should handle everything. All routes through the section must be long enough to handle your longest loco consist, so I show the section extending along the main past the points of the lowest turnout. Isolate both rails at all connections. An entire train will not fit in this short section. If all your rolling stock has plastic wheels, it doesn't matter and you're done. If you have steel wheels, you will need to add a short section of electrically dead rail long enough to hold your longest truck. If you have illuminated cars you will have to consider a more complex solution because when the lit car spans the dead section, you'll have double the voltage across the bulb and it will probably blow out. A rectifier with a voltage regulator in the illuminated car may be a solution, but not one I've ever heard tried.

As for the crossing, the best bet is to put an auto reverser on the two problem frogs.

Re: RETURN LOOPS

Vollrath, Don <dvollrath@...>
 

You have 3 reversing track sections that would need to be or could be auto-reverse controlled. Not sure if the X-crossing is at grade or is an over-under pass w/ no rail connection.
Easiest way to implement is to provide isolated rail joiners (both rails, both ends) at the turnouts leading to each end of the reversing tracks. You could get by w/ only 1 or 2 A-R units depending on how many trains will be running at the same time w/o restrictions. Start by wiring all 3 track sections together at the output of your A-R unit. If you run only one train at a time, having one A-R unit will work w/ no polarity problems. Train length vs track length could complicate wiring if trains w/ steel wheels will be longer than the minimum reversing track section length.

Re: RETURN LOOPS

Blair & Rasa
 

Ray
I'm not sure why you are trying to distinguish between a "return loop" and a
"reversing loop", as in both cases you end up with a train returning to
source on rails of the opposite polarity to original, necessitating a
polarity reversal - either automatic or manual. In your case, I see three
such potential reversing sections. It is very difficult, however, to
discuss without some reference marks. Might I suggest you repost the
drawing with a letter beside each switch - then we can discuss in terms of
"the section between A and E...." instead of "um, the switch about 1/3 of
the way down the left side that diverges to the right and immediately..."
Also, some general commentary as to your vision of how the layout will be
operated - single operator, single engine, switching empire, or three
trains, three operators, playing chase your tail", would help us discern how
the layout needs to be wired.

Thanks
Blair Smith
