12x12 layout Questions!!

[lionel2]

Do i need two or more sets of lockons for this size layout on each line??  or will one lockon closest to transformer be okay??  I am using a Z to power my trains.  Its postwar O gauge.  Cause i heard that the train loses power the further away from lockon it goes.  thanks.

That depends on how many feet of track you have.

A simple oval, NO.

If you made several loops with several switches, You might need more. If you run several powered engines and lighted passenger car. Watch it lights. If they dim then add another. If your engines slow down, again Yes.

What would help is making sure you clean the contact pins as you assemble the track.

I have a 12 x 12 O27 tubular layout and I have included 6 seperate lock-on positions, which I then developed into blocks.  I run mulitple routes as I have many switches, and the added lock-ons definately assist in delivering consistant power.  I run the newer ZW power in conventional mode and also have the layout wired for TMCC, for my 2 Command control engines.  I think adding additional lock-ons will be well worth the effort in your case.

I would just run it and see, then add feeders as needed.  But for that size of loop, probably around 40 feet, with decent rail joints (or, best, soldered joints), and a single block, it is very likely that you don't need feeders.  Consider that the farthest point of the loop is only about 20 feet, as the train runs, from the transformer and is fed from both ends.  That is equivalent to being only 10 feet from the transformer on a track that is not a complete loop.

If you do find that you need feeders anyway, use 14 AWG or larger.  Anything smaller will not make much difference compared to the track itself.

You mention "each line".  If you have multiple loops, I'll bet they get near each other at some points.  You can reduce some of any voltage drop by tying the outside rails together, loop to loop, at those places.  That way each loop acts somewhat as a feeder for the other(s).  (I assume that you have the transformer common, the U terminal, connected to the outside rails.)

Why my feeders didn't help much originally.

well...i tried just one lockon, it works great!!  prolley because of the power of my Z's.  I got all 4 of my transformers running for my layout,  i have 20 accessories hooked up to my 4 transformers.  Just 2 or 3 accessories per posts.

Congratulations!

I believe i need to add another lockon at the other end of layout.  cause my switches closest to the lockon get very hot from the 25 volts my Z puts out.  thanks.

If you are using the 022 switches for O gauge install the constant voltage plugs into the side of the switch and set them for around 18 volts, use handle B or C on the ZW transformer with just the switches hooked up. Also wiring the switches that way you will be able to have an engine go through the switch slower.
