I would like to wire my layout the same way it shows in the picture  here hoping it would stop the stalling of both my tmcc and legacy engines can this setup be done??I have the Lionel TPC 400 and the Lionel Legacy hooked up to my current layout what gauge wire would i need if  went the that rout shown in the picture could I use the MTH 24 Port Terminal Block / Strip and could I wire my layout the same way shown In the picture showing wires going to section of tracks

I don't run command and sound either; the electronics remind me of past work the mood has to be just right for me to enjoy them.

Interference is a case by case thing. I've worked on electronics that would refuse to operate correctly based on what outlet in a room was used, what type of hight voltage step down to local 440v was used, etc etc.. Just be confident very few folks don't track down their gremlin or have many (but a select few have put more than a fair share of effort to win... Cross the fingers; good luck )

The chicken wire is an issue,  gypsum content of wall material is another.  Either of the two can perform sheilding.

If I'm not mistaken the signal is run in the household ground. But regardless, one of the three is the carrier.

The answer is here somewhere if you search... but I usually try simple stuff by trial and error process of elimination and there's only two things to try and experiment with.

1. I'd start with the ground and try to simply run a wire along the "nice tunnel   ceiling to household ground. (Assuming it has a modern ground installation).  Use an outlet cover screw, that's should be ground. At the transformer is fine. If that didn't help, 2. a cheap extention cord would run the other two at once. But I'm pretty sure it's ground vs piggybacks on the two active lives.

How are you going to deal with the tunnel portals vs new track dia.? Tear it out, or only tear out what's needed.

It's always a shocker to me to a nice one like that get razed

Yes, you can definitely wire your layout like in the diagram you show. It is always good to have even power distribution. For a layout of your size, 16 gauge wire should be plenty good. You can use the MTH terminal block, but you don't have to. Wire nuts at the wire junctions work well enough.

I just want to make sure you are clear on the fact that that re-wiring the layout will probably not fix your TMCC / Legacy problem. TMCC is not picky about perfect layout wiring. (DCS is, but TMCC is not.) At my parents' we have a layout that is something like 17 x 30. It was built over the course of a decade, and the plan changed a few times. It was wired with whatever was lying around, or whatever was on sale. It's a rat's nest under there. And TMCC works just fine. What TMCC is picky about is interference. And that, I think, is why you are having trouble at the tunnel, because it is creating interference.

What Adriatic is suggesting, basically, is to get around the interference problem by putting a TMCC antenna inside the tunnel. Definitely try that. Get a single wire, and crimp one end under the screw in the center of the wall plate on an electric outlet. Make sure it is a 3-prong outlet. Run the other end thru the tunnel. The wire must not connect, electrically, to anything other than the screw at the wall outlet. This wire will serve as an antenna to get TMCC signal into the tunnel. See if that helps. (Try a couple outlets if the first one doesn't work, just in case you have non-standard wiring on some of them).

Unfortunately, Lionel's own documentation is not always super helpful on TMCC signal issues. The late Dale Manquen did us all a great favor by figuring this stuff out some years back.

Outer loop. It stalls at the curve section marked  with a black dot on the layout right before the main big  mountain tunnel begins.

I still don't understand why the engines stop at a single track that is outside the tunnel, but then I don't know anything about TMCC. I would think that if the chicken wire is the problem, the engines would stop somewhere in the tunnel.

Be that as it may, you said in an email that you laid a piece of solid wire near that spot and the problem went away. That suggests the signal is the problem and adding multiple power drops should fix things. Here's a diagram using your design with 3 power blocks. If this were DCS, I'd have twice as many blocks, but 3 might be enough for TMCC. The large brown rectangle is the transformer and the smaller one is a terminal strip. Maybe 14 gauge from transformer to strip and 16 or 18 gauge from there to tracks?

Did you try the conventional test? I assumed you had. If it stalls in conventional without a system hooked up, just a transformer, then you have dead track there.

Is it stopping inside the tunnels as you began with, outside the tunnel, or both, and what temp. solution was applied and what changed if anything....???

A weak connection could stop the signal also. Not 100% bad, but weak.  With a train on the problem track take a voltage reading from that track compared to elsewhere. I.e. a bad connection can flow low amp at full volts, but try to pull any amps and the voltage drops fast and hard; maybe stops flow altogether; a signal is even more sensitive to any weak connections.

Anyhow, I think you'll know soon enough if the track was the issue or if the signal is being blocked.

Mark those track sections where it stops now as you pull it out so later you can address it.

It stall at the before the tunnel the I give it a shove it starts  up then stalls inside the tunnel

Ok . Are there any power connections to bus, between these two points? 

You may have two issues. One section of bad track and signal loss in the tunnel. Run the "ground wire antenna" test see if it helps either spot. There is also another thing having to do with close parrallel track field isolation, but it's complicated. Start here if you want to hunt before you do anything.

 

Widows under the layout!  

  Actually, that happened to a cousins ho layout. A "pet" got away. He raised and sold scorpion, tarantula, widows, and rattle snakes.

  Once she spun a web he got her.  He sprayed something chemical, and something herbal at the doors and vents plus did a bleach washdown. Never did see the train run; the room, in between the washroom and lower level garage was sealed and off limits for the winter so a out a year total. But that could have been my Aunt & Uncle's call AND he was breeding ...? 

Call a pro. 

  If you can catch them without dying there's a market. They weren't cheap. But they love to get out and babies are oh so tiny. A bunch of tarantula would have sat better with me .

MTH bus wiring

If I did the way Dave's diagram  shows in the photo  can I use this MTH  block terminal when bus wiring my layout

That was just a basic idea and not intended to be an actual wiring diagram. But yes, the MTH terminal strips can be used, though there are many terminal strips on the market.

In any case, the diagram shows Block Wiring where main wires are run to 1 or more strategically located terminal strips and from there to individual connection points. Rather than run 3 long wires to each connection point, you run 1 long wire to the terminal strip and then shorter wires from there.

This photo shows Bus Wiring where 1 (or more) main wires are run around the track and then much shorter "drops" are connected to various points. In both examples, the idea is to separate the track into blocks and then run wires to a track in the middle of those blocks so power gets distributed fairly evenly.

  A terminal block can help you keep things straight by labeling &/or a list, and it can speed connections along by avoiding some splice work, but it isn't a necessity. I use an older "universal" no-name terminal block and like to cut apart nylon euro terminal blocks for the screw set splice ability vs connections vs a crimp, etc.. (the best blocks have a wire gripping jaw inserts connected to the screw tip vs a screw tip alone. Without finesse the tip can mangle and cut wire if it gets turned too tight... they still work ok though)

witch wiring diagram would be best to use with a terminal block  so I can get  started  as soon as I get rid of the black widow spiders they have made there home under my  train table to keep my Tmcc and Legacy engine from stalling on the layout

Like I said, I don't know anything about TMCC, so I'm going to have to let someone more knowledgeable comment. I don't know how many blocks this size layout should have, how many tracks in each block, etc. With DCS we tend to break things into blocks of 10'-13' lengths with 10 joints per block and the center tracks are isolated between blocks. We tend to use what we call Star Wiring, which is like my first example, though some use Bus Wiring too without problems. Maybe Adriatic will comment, but if no one responds, perhaps this is a question for the Electrical forum.

Reaching out to Adriatic about the the two diagram witch wiring diagram would you use if you were in my place adding a terminal block one diagram has more wiring around the layout then the other diagram tying to take care of the stalling of both my TMCC and LEGACY Locomotives

I'm pretty sure Tmcc blocks are more about separation of of additional transformers/ bricks, than being there for signal reasons like with dts.    With Tmcc the feeds don't HAVE to be blocks, but can be drops instead. A drop off a bus still delivers power easier than rails alone can. Plain and simple, the more drops the less voltage drop, which is good. 

Actually. This wiring isn't really 'blocks' to me because it's from one source. It's a bus and drops to equalized isolated branches, but I roll with it

DC's likes equal branches I guess. Tmcc doesn't usually, if ever, suffer from it that I've heard of, so why not?   I often build with "if" in mind. 

IMO The only reason to differ would be focused more on conventional running alternative, where I like to add power drops in the curves because that's where they slow down and a good feed really helps. But Dave's second grouping actually looks pretty good for both dts & conventional both. The Tmcc is less concerned and just wants it's unbroken track path and signal airspace around it. 

I had the last tab open for for hours before using it, didn't see the question right away 

The more drops the better, but it may or may not help any signal issues. Those signal issues never have one single cut and dry or one size fits all solution. A solution is found beginning with a process of elimination.

I can't even take a stab at it  without the results from the conventional testing; I don't know your even getting power there on the spot outside the tunnel or in. 

Mostly when folks ask a series of questions it is in an attempt to piece together a puzzle. I didn't get enough answers to do that .

With more drops a terminal board would be nice. That's why they are made. But nice and necessary are two different things.

At this point I'd likely set up the new track loosely, and use the wire you have. If the problem occurs again with the new track, then you know track is not the issue and you can address the signal alone; before the track is perminantly set.

I talked to my friend Jose hes is the one who made the tunnels and did the art work he told me he want's to redo the tunnels and remove the chicken wire from the tunnels what do you think Adriatic he also notice signal drops in both the TMCC and LEGACY engines
