I'll toss in an opinion which echoes those of others. The diagram looks OK for the reversers I use, which are by DCC Specialities. I don't know the MRC unit. So I'll pose a couple of ideas: If the MRC

I used 2 MRC Reverser Units on the MWR Train Museum N Scale layout. This is on a Digitrax system layout. Both ends of both sections were totally isolated. That is, 2 isolating rail joiners at each

Sorry for the multiple posts, my computer crashed twice while writing that post! Jay

I was watching a video and they mentioned binding the wires in a loco to keep them out of the drive. It was something about a waxy threadlike material that sticks together when you press it to hold

Not familiar with anything that sticks together, but dental floss works fantastic for bundling up wires. We all have that package of floss that our dentist gave us...that we never use :) Craig

I have used “Bees Wax” from craft stores in sewing department. Slightly sticky helps string stay together. Kurt

Charles, disconnect the two output wires from the MRC unit. Then with power ON verify with a voltmeter that there is near zero volts across all 4 loop isolating gaps. If it is not zero you have an

This is typically referred to as cable lacing. http://www.aeroelectric.com/articles/cable_lace/cable_lace.html Mark P Stamm Mark at Euphoriatt dot Com Sent from my mobile device

It’s called Stator Lacing and Tie Cord. In another life, we used it to bind rewound coils of wire for motor stators and armatures. It is a braided flat cord (cotton?) that was coated with wax, or

Made a few updates. Thanks all for the advice. https://www.dropbox.com/s/oqbriyxcawabj5t/SCARM%20-%20playroomScarm_v30.pdf?dl=0

HiTom, You won't regret those changes. That's a lot more reasonable while still giving you lots of options. Like it! Wouter

Better.... Tom, Run some of the Green Track...while also making an attempt to run the Roundtable. On the way to doing this... Consider some Structures and Scenery as well as spacing. I expect a few

If I go with servo-based switch machines (e.g. Tam Valley or Walthers), how do I power them? It would be a pain in the posterior to have to provision AC and then a bunch of wall-warts around the

Dave, I have a 12 V DC power bus that runs around my layout. Then use small adjustable regulators from Banggood.com set to 5 V to power my servos. Paul O

Hi! You power both systems from the DCC Bus or a 12v supply. The control boards supply the power to the servos. Jay

A friend of mine uses a different approach to keeping wires out of the motor of a locomotive. He uses Aleene's Tack-It Over and Over. You can use the adhesive to hold down wires and you can peel

Walthers makes a 12v PS {filtered} to go with their new LCC switch control;. Keith

As updated there are no reversing loops except for the turntable itself. DonV

Hi Don, Are the turntables always in need of an auto reverser by default? Thanks, Tom

Hi Tom: We added reversing cam switches to the turntable shaft. They work OK, but there is a dead space where we have no tracks. You can also use a toggle
