Steven,
?
There are many different ways to isolate the rails of an electrical block.
?
The method I use is rather simple. I apply super glue to the rails at three ties on either side of where I want to cut the rails. I use the super glue not super glue gel.
?
After I am sure that the glue has dried I generally use a razor saw to cut the rails. I have also been know to use a Dremel jewelers cutting wheel. After I have cut the rails I apply another drop of super glue between the cut rails. When that has dried I use a 1200 grain sand paper to clean the top of the rails. The super glue between the cut rails insures no future short.
?
The above has been working great for me for over 20 years.
?
While it is not always necessary I always cut both sides of the rail at each rail at each end of an electrical block.
?
BTW I used the PM42 as a circuit breaker from the introduction of the PM4 until the introduction of the BXPA1 and BXP88.

Re: Peco Electrofrog - dead leg

 

If your solder joint doesn't start to make immediately, you probably need more cleaning. You can wipe the soldering iron tip on a sponge or damp paper towel, folded several times. For the rail, a fiberglass scratch brush works great as well as a wire wheel for a dremel (be careful of the ties). Other methods of cleaning the webbing on the rail work, these are just what I use. (I really like the scratch brush, it's fast but doesn't seem to bother the ties.)

Re: Digitrax PM 42

 

Yes, you need to separate the districts electrically. I have my version of the Red Oak Line and have a PM42. The front track is Zone 1. The hidden staging tracks is Zone 2, The hidden Staging tracks for the Interchange is Zone 3. The Interchange is Zone 4. The nice thing about using a PM42, is if you accidentally short a track, it does not shutdown the other Zones. I have plastic insulators on my layout. If you have already laid all your track, then you need to decided which tracks belong to which Zone and then use a dremnal tool to cut very small breaks in both rails. Cutting both rails is important.

Strictly not necessary, I would agree, but three factors warrant it in most cases, to me.
1) there may come a day when another booster is added; it's not advisable to connect either rail in this case.
2) there may come a day when it becomes necessary to make a section autoreversing, and the gaps will be needed.
3) when diagnosing a short circuit, having isolated sections makes the number of possible problems fewer.
Agreed, there will always be use cases that speak to other alternatives, but exceptions-to-the-rule need context.? In your case, you know what your doing, and can make a value judgement.

Just looked again at the video. He answered your question in the comments:

"I assume you are referring to the pushbuttons with the internal LED’s in the yard ladder I showed in the first control panel video. Those came from and are an LP1-OA-1-A-G with the last letter indicating the LED color, in this case green. They are $2.12 for 10 or more but the price does continue to decrease with increasing volume. I just checked and they still have them."

Looking for lighted push buttons

 

Larry Puckett (the DCC Guy) has some videos on YouTube where he explains how to build control panels. On one of his yard panels, he uses a lighted push button that lights when pushed and indicates the route going into that track is lined. He does not mention where he purchased or who makes the push buttons. Has anyone used something similar or know a source for these?

Re: Peco Electrofrog - dead leg

 

The key for soldering is speed.
If it takes longer that a second to make the joint, back off and try another technique.

I don't use resistance soldering, so have no idea how that works in real life.
Using a soldering iron, the correct solder is crucial.
Wrong solder:
can take too long to melt.
have acid flux (eats up wires and copper on boards).
not be best conductor.
hard to handle.

Also, more solder is not always better.?

Re: Peco Electrofrog - dead leg

 

Allan,
? I have a -few- Peco turnouts that have those wires.? They are all double slips.
If Peco has adopted an attitude/practice of "we'll do this for all turnouts" then
that helps anyone who is buying new.? I purchased my turnouts only about 2+
years ago and most of them do not have those wires.?
? I wish Peco would live up to their promise of "rolling out" (converting) to the
Unifrog method - they know how to do it but are dragging their feet on that
promise.? I might even replace all of my yet to be installed turnouts with the
Unifrogs ... but if they aren't available "across the line for all turnouts" I'm
probably not going to do that.? Probably.

Re: Peco Electrofrog - dead leg

 

Hi Jim,

Peco Electrofrogs, at least in recent history, has a wire attached to the frog that you can solder to, so that you don't have to solder to the frog.? Of course, the Electrofrog is being phased out for the Unifrog.? The tiny portion of the Unifrog that can be powered also has a wire for it.

Peco Electrofrog - dead leg

 

Hi all,

? I was soldering feeders to an HO Peco Electrofrog turnout using resistance
soldering.? I kept the heat on it too long and heard a "sizzle".? Sure enough
when I checked with my meter one of the short legs off the frog is dead.? The
dead part of the turnout was the segment between the frog and the points
but I am certain that the solder joint that 'sizzled' was the one on the short
(non-points) end of that wire since right above it was where I was working.
? I was soldering the feeder(s) into the web of the rail on the outside of the
rail?where the wheel flanges run.

? There are two fairly small wires that bridge the frog and provide?the
power continuity - each is a little over an inch long (1.5?).? They are
spot soldered at the factory to the underside of the rails on both ends
and embedded in?the plastic that forms the frog.
? What happened is - I'm deducing - the heat broke (unsoldered) one of
those factory spot solder joints.

? So - be extra careful when soldering to the short rails on the 'inside' of
the?turnout (the side of the turnout that is away from the points).? If you
do break the contact you can fix it ... but you are not going to "like" it (it's
not going to be "pretty" and will require some 'contortion of your hands to
get to where you want to solder).

? I would also recommend that you try to solder feeders to your Electrofrog
(and?Insulfrog as well?) turnouts before you install them on the layout.? If
you are clever you can probably even figure out how to do that on the
underside of the turnout where the feeders won't show at all.
? On my layout all turnouts are gapped on all 6 legs - and insulating
joiners are used on all 6.? The reason why I'm doing this is because I
will be detecting occupancy of the turnouts and using that status to
prevent (minimize?) throwing the turnout under any equipment.? "If
it's occupied - don't throw."? This is being done using LCC - for both
the detection and the decision whether to actually throw or not.? Yes,
the push button for the "throw turnout" request is momentary.
