Thanks for the response Paul.  I saw the 15 number on the website.  What about the length of the buss run?  Is there a noticeable power drop off the further away from the module the run goes?  Does that 15 locos drop down to a much lesser number if running numerous locos out in the "boonies" as it were, and thus drawing down the power on the entire circuit for that module due to the distance from the power source?  Jeff

Quick update, there was a short circuit in the module and Ring will repair at no cost.

Under the "New Users Start Here / Introduce Yourself" thread, Jeff asked, "Any input on how to go about installing the system, i.e number of power modules needed, where to locate said modules ( grouped in one place or distributed about the layout) etc. and any other tidbits will be greatly appreciated."

As they say, "it depends...."
Ring advertises that the PWR-56 has 56 Watts of output power to drive 15 or more typical modern HO scale locomotives.

I have three on my layout. My layout is an around the room, double-deck arrangement with a center peninsula. The room is ~21' x 20'. I have a construction blog about it over on the MRH website (I think you know that). Just search on "SP Lordsburg Sub - Construction".
* One for both the upper and lower return/staging loops  - each has seven (-7-) tracks.
* One for the lower operating level.
* One for the helix and the upper operating level.

Based on the way I have them allocated, I'm thinking I won't ever approach having 15 locos on any one of them simultaneously.
Mine are all located in one central location in the center peninsula, so its not a long reach to any part of my layout.

Hope that gives you an idea of what you might need for yours!

i don't have a photo handy, but when i did this i added a covering of Kapton tape to the module to protect the "guts" from an inadvertent short.  the install turned out fine.

go for it!!

I definitely share your concern on lack of availability of product, it was my concern when I decided to kneel at the Railpro Alter and go for it and jump in and see what happens. Got a little more concerned when SSS - Scale Sound Systems, whom I spent like $1100 with when I invested ... said they were not thrilled about selling RP, and didn't reply back to me via email when I told them what I wanted to order.(Above $500 worth) Just blew me off.

Everybody here sayes - "Not to Worry" RP isn't going anywhere. Just hope they don't crash, burn and fizzle.
I really like the system - so easy to use. DCC looks cool, but has alot of moving parts, lots of CV's to monkey with - finicky with dirty track ..
yata-yata ...

I think they have a pretty solid market on the Large Scale stuff, just hope - there is hope !

Anyone else get a warm and not so fuzzy feeling ?
