Connect multiple feeders to same screw on 12 port MTH Terminal Block

Bryant,

I have a few blocks that are getting their power from 2 , sometimes 3 power feeders in one block.

If the feeders are going to center rails that are not isolated from adjacent center rails, that's a bad idea.

If the center rails are isolated from each other, then you actually have 3 blocks andthat's OK.

Can I piggy back them to one terminal on a 12 port  terminal block making that terminal responsible for all the power in 1track block?

Yes, you can.

Or is that going to work against good DCS and in addition Legacy operation. 

Multiple feeders to the same track block is the issue, not so much where you land the wires.

Regardless, Legacy operation isn't affected either way.

Barry,  If you look at the page where the 2 insulators are, am I correct that I should not have more than 1 power terminal between the insulators?

Bryant,

Yes, that's what I meant, i.e., you should have one and only one track connection per block. A block is is delimited by insulated center rail joins.

Thank you all.  Moving forward.  Time to re-read the book.  2 handle transformer to run conventional is my goal.  Good to have the ability.  For the most part I will use.DCS and can run Legacy too.

Barry, if you're running a smaller layout, is it possible to run one wire to the track to the tiu instead of running feeder wires every ten to twelve sections of track, and still get the dcs signal through the whole layout?

if you mean from like I changed above then "yes" it will work but signal might not be strong in all places.

You can try and, depending upon a variety of factors, it may work well (or well enough) to suit your needs.

However, I'd break any loops into at least two (center rail-insulated) track blocks each and run a TIU wire pair to each block.

That way is almost sure to not yield maximum signal strength. Multiple TIU connections to the same track block often has very unpleasant results.

Barry,  I added in yellow potential center insulation points which are marked in yellow.  I made sure that there would not be more than 1 power drop between insulators.  I also ordered a 24 port terminal block with intention of running 13 on one and 11 or so on the other terminal block.  Based on what you recommended, does it look like I am covered?  Thanks.

Bryant,

It looks reasonable.
