Number of PWR-56 Power Supplys for a Given Layout
« on: June 13, 2026, 06:13:25 PM »
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!

Good to know Espeelark, Mine will be 3 levels, 3 should be more than enough for me. Say if 3 triple loco consists get into 1 power district(9 locos)
Should be good still even if old units ?

First level is a 15 track stage yard, so maybe two consists (6 engines) moving at once, +helix up/dn.

Level 2 is for running and switching, worst case maybe 3 consists running (9 engines ?)(3 engine consists - more or less) +helix up/dn

Level 3 Mostly continuous running  - same a level 2 (9 at most) - will have engine terminal/roundhouse, may use level 3 to power helix ?

Doubt 1 person could handle all that, not even half on a good day, but when grandkids start coming into the picture - etc...?

15 modern locos = maybe 8 older blue box/atlas yellow box/ P2ks locos (Which I have alot of)...

Maybe 4 would be better ? My room is 14 x 18.
