I am using 14 gauge wire for bus and 20 gauge wire for feeders.
I am not sure which type will work well for DCC.
I have a Mouser catalog which sells several types.

Re: Peco Code100 Points

Vollrath, Don <dvollrath@...>
 

Well...a combination of lucky & smart.
1. With electro-frog you recognized the need to provide insulated rail joiners at the diverging frog rails and permanently wired power for other track extensions. Good move.
2. But with a brand new switch you don't yet see a need to have the point rails and metal frog powered through extra rail feeders and a separate external switch. So far you have good connections to power those rails. Just wait until the points get dirty and internal connections start to corrode.
3. Without derailments you have not yet seen what happens when you get a wheel to opposite polarity point rail short while the point rail is being powered through the tiny contact area of the opposite point from a 5 or 8 amp booster. As soon as you burn the points good once or twice, re-read #2.

4. With insul-frog you don't need the insulated track joiners at diverging frog rails as those rails don't switch polarity. The frog itself is insulated. But now you have a known dead spot in the track. Usually works OK with all-wheel pick-up on diesels.
5. You can still have something similar to problem #3 above as connections to the inner turnout rails are bonded together be metal to metal contacts in the plastic molds rather than good solid soldered connections. Eventually you will wish you had added more rail feeder drops.

You don't HAVE TO do anything to these switches to run trains with DCC (except recognize the need for #1 above). Your luck and annoyance level may vary. Making them more DCC Friendly simply reduces the probable occurance of occasional annoying problems that takes the fun out of running trains when they keep stalling at track switches.

Subject: [WiringForDCC] Peco Code100 Points


I am new to modelling and trying out wiring of points prior to
building layout.
I have read a lot about wiring of Peco points, so tonight I set up
three straights with a point to see what happens.
I did it with both Elctrofrog and Insulfrog.
With Electro I used insulated joiners on the frog rails and no other
change and all three straights have power feeds and everything ran
with no problems.
I then changed to insulfrog using the same straights and metal joiners
on teh frog instead of insulated and again no problem.
Is this because I am not using a point switch for switching the frog
power or am I just lucky that I am not getting shorts.
The electrofrog is the same as the code 55 and old turnouts in the
wiring peco turnout section of web site.
Can someone please explain why I was lucky.
Thanks

hi
I am fairly new as well and have probably just read the same articles as
yourself and have done the same tests as yourself. The only difference is
that I am using code 75. I have gone for power routing of electofrog, to me
this seems to be the catch all except maybe thats its a little more work and
perhaps a little more expensive in that you have to provide a switch. Having
said that you have no dead spots even if you are running small shunting
locos at slow speed and no shorting problems with larger out of tolerence
locos. I have just started laying and so far think I have made the right
choice although I am sure there are many who will dissagree

Best of luck

Re: Circuit Schematics

wirefordcc <wire4dcc_admin@...>
 

Ray,

I see that another update to my webpage is in order. I used peak
and average in the following ways: The peak circuit will cause a
meter to read whatever voltage the circuit is attached to. The
average circuit will hold it's value briefly and it won't see
peaks. Unfortunately to the electronics savy, peak and average
reading capability also refers to measuring AC waveforms. Shame on
me for not making that clear in my webpage. I'll fix that at the
next update.

Which one should you build? Either one. When it comes to DCC, you
should read the same thing. I built the "averaging" one because
when I'm squatted down measuring my garden RR, I'm only momentarily
making contact and I didn't want a reading that jumped around. I
wanted to capture the reading briefly.

On the downside of the averaging one, because it does hold it's
reading, you need to let several seconds go by before you take
another reading.

Banana plugs is the name of the typical plug that is on the end of
the test leads for digital voltmeters and other test equipment. The
sides of the plugs LOOSELY resemble banana peels. Use your
imagination!

Alligator clips is the name of the typical clip on test leads for
clipping the test lead to something that you want to measure.

Re: wiring a helix

Vollrath, Don <dvollrath@...>
 

Nothing special required. Same as straight or curved mainline track. In the case of a helix, run the DCC bus up one of the helix risers and connect to the track at each level. Be sure to solder all rail joiners except for one pair on the side opposite of the DCC bus to yield good electrical connections, but yet leave a little room for rail movement for thermal expansion, etc. You may want to add insulated rail joiners at top and bottom of the helix to facilitate train current detector or reversing loop wiring at a later date.

I ma an NSCALE modeler using ALL Digitrax DCC equipment including one
of their power supplies (I have 2 more if needed for future

Circuit Schematics

rayfreeman3 <rayfreeman3@...>
 

Allan,

On your web site "Wiring for DCC" in Track Wiring, Part1, you have a
circuit diagram under the topic "Measuring DCC Track Voltage and
Current" Which shows leads to the track through a diode, capicitor and
resistor to a DC voltmeter.

Under this is two tables, one for Peak and one for Average.

Just to be clear, are you suggesting making two different instruments;
one for measuring peak volts and one to measure "average" volts using
essentially the same schematic?

I'm also afraid I'm not clear on the Alligator Clips vs Banana clips
immediately under this. Can you illuminate me?

What exactly is "Hybrid Drive"?

What exactly is "Hybrid Drive"?
I see the term used on the web in relation to some feature of a Lenz

Anyone on this forum ever get an explanation or even what the
benefit/advantage of Hybrid Drive is?

Re: Terminating Bus Ends

wirefordcc <wire4dcc_admin@...>
 

Mike,

I don't think you need to worry about terminating your bus ends. For
one thing, you have relatively short runs - 10' in each direction.
Second, you are using Digitrax boosters which don't seem to exhibit
the problem other manufacturers have.

Still, it won't hurt if you add the terminations. Or for other
readers of this thread that have longer runs or other manufacturers'
equipment, here is a link to the section on adding terminations to
your buses: http://www.wiringfordcc.com/track_2.htm#c2

Re: Atlas Code 55 NScale Turnouts

wirefordcc <wire4dcc_admin@...>
 

Mike,

I'm sorry I don't have your favorite turnout on my website. Since the
website doesn't put food on my table, I can't cover everything. Some
manufacturers send me stuff and sometimes modelers send me turnouts to
look at. But even if I had the turnouts to look at, I'm working full
time and going to law school part time. So updates only happen at the
end of the semester. Until I figure out how to make a money making
venture out of this website, I'll keep doing the best I can.

I'm not sure if I know what your question is. I wouldn't expect the N-
scale Atlas turnouts to be any different than their HO counterparts.
Use the HO information on my website unless something is definitely
different. Let me know if there is a difference. The next time I go
to the train store, I'll take a look at one of the turnouts.

Assuming what I have written for the HO turnouts applies to your N
turnouts, my website describes how to wire each manufacturer's turnout.

You don't have to worry about burning up any decoders. There really
isn't anything you can do wrong. I can imagine some pretty far out
screw-ups like wiring two boosters together or wiring a booster to
your turnout power source that would cause you trouble. If you follow
the wiring practices on my website, you shouldn't have any trouble.

If you can articulate a more specific question, I or someone else on
this forum will be glad to try to help you.

Atlas Code 55 NScale Turnouts

Michael Langford
 

List,

I am in the process of trying to figure out how to wire the new Atlas
Code 55 NScale Turnouts for a full DCC layout. I am using a Digitrax
Chief System. Your wonderful website doesn't seem to address these
turnouts. It seems to be a little out of date but it is still one of
the best references on the Internet.

I have a small Interchange section with 12 of them on it. Some
creating crossovers and some for stubs. The new turnouts have a
small tab on one side with a hole for soldering or using a screw.
The instructions that come with them all reference to the Atlas
switch machines BUT I am using Tortoise slow motion machines. I have
been trying to figure it out before I burn up a bunch of decoders.
Can you help me somehow?

I am uploading a JPEG of the interchange for you to look at. IT has
changed a little after the LDSIG gave me input but the design is
almost identical except for the distances between the switches.
Thanks in advance.

Yours Truly,

Re: Resistance Soldering

wirefordcc <wire4dcc_admin@...>
 

I'm glad to hear that people are watching the resistance soldering
video and getting something out of it.

You're right, the solder doesn't stick to the hemostat. I think the
hemostate is chrome plated. After about 7 years of use, some of the
chrome has come off my hemostats. Occassionally, it now sticks. But
until you mentioned it, I hadn't really thought about it. The solder
never flows around the hemostat. It does sometimes flow under the jaw
and does solder your wire and track together on the other side. But
not as much as you might think. The reason is that the hemostat sucks
a lot of heat away from the rail. So yes, things work out just like
in the video.

Happy Thanksgiving everyone!

Remember, hemostats make great stocking stuffers. Resistance
soldering stations make great Christmas presents. My wife says I
don't need any more locomotives. If I don't need any more trains,
what am I living for??? :-)

Resistance Soldering

jmscnw <jmscnw@...>
 

I will be purchasing a Resistance Soldering station soon but have
a question regarding demonstration video on WiringForDCC site:

It appears you are clamping down other end of wire with a hemostat
or other type of clamp. Won't the solder flow around the clamp and
fuse itself to the rail ? This doesn't occur in the video clip
so I am wondering how you accomplished this.

Decoder for Japanese Kato

The Newark part number is for a metal film resistor, Not wire wound.
I just like to see things run cool to the touch as much as possible.
For 54 cents a resistor, it's money well spent.

Hot is a relative term. Power resistors normally are hot to the
touch.
There is nothing wrong with using larger resistors if your goal is
to
reduce any discomfort you have in working with them or coming into
contact with them. But it not required. There is not enough
power to cause any fire hazard or burn.

You can always use a series string of resistors to spread out the
heat.
Example: you could use 3 1/2W 39Ohm resistors in series. That will
give
you a long 117 ohm 1.5W resistor. The resistance accuracy is not
the
critical.

Sorry...typo...39 ohm series...somehow I must have hit the zero button

Mark, shouldn't that read .....1/2W 390Ohm resistors in "parallel"?
I thought wattages are additive in parallel and resistance is
additive in series? Or am I all mixed up?
