Question - how does power get from approach track to turntable and from turntable to roundhouse since the tracks are not joined? Must be a simple answer - please advise. Thank you.
It’s been too many years to remeember; but I am guessing…
(I’ts a simplistic device) Power get its power from the approach track - or needs to. Should be automatic (pre wired).sideside Are there separate terminals for the turntable tracks? (Look on bottom or frame).
Power to ‘indexed’ tracks should be blocked and fed individually via DPDT-centeroff -(reversing) toggles.
Indexing was via blank cogs in a large cogged flywheel. Turntable is turned by optional motor, or by hand crank.
LAST WORD would be from Atlas’ Customer Service request for “instuctions to wire an older, used” model. It’s been available for 50 -60 yrs.
I think to provide power to the turntable tracks there are two contacts around the edge to feed power to. (fairly sure)
As for the roundhouse tracks, you need to supply power using feeder wires to each individual stall, best to use a toggle switch to cut power so locos can be parked in the RH. The round house is not intended to get its power from the turntable.
Club has one, but I won;t be around to look underneath til Sunday. But I was thinking power went to the center of the Turntable bridge itself, and up to the rails.
Use switches for tracks in roundhouse. Here is a look at the Atlas TT.

The feed to the turntable track is a pair of terminal screws on either side of the crank/motor drive. It connects to a split ring underneeth and automatically reverses polarity at a point when the table passes the drive. The track slots around the table have a letter embossed on the bottom (it will be covered when the track is installed) when it goes from A to B, the polarity reverses.
The feeds to the tracks is correct as stated above.
This is correct, 2 screws , 1 on each side of the TT motor area. Care must be taken to wire it in the same polarity as the approach track, very simple, DCC ready.
The power to the TT is only for the turntable tracks. All the tracks leading to or from the turntable have to be wired up individually. My last layout used an Atlas RH/TT, IIRC I was able to wire all the tracks together under the roundhouse with two leads going to power, with an on/off switch so I could kill the power (DCC) to all six tracks if I wanted to.
I wired all my turntable stall tracks to individual toggles, so I could leave the engines powered off when not in use. I was thinking DC at the time, and once I started using the turntable with DCC, the toggles seemed unnecessary. Then, I started running sound engines, and I was glad that I had wired in the toggles.
