Atlas O Turntable with MTH realtrax and DCS?

Just cut off the end of the track. You need a falt end to butt up against the turntable. As for DCS and Legacy control, as long as you have feeders on every turntable leg and good connections you will have no problems integrating your turntable in with your command systems

Would the adapter track sections mate up without modification? 

Juice,

I don't know the answer to that. I'm curious as well.

Use and modify the Realtrax "to" the turntable.   You will have to cut away the plastic roadbed to fit.  You might also have to make some height adjustments. Save yourself some pain and use Atlas Track for all of the "Whiskers".  The tracks (TT and Whiskers) get hooked up just like your main lines and DCS engines will work fine.

I have a bridge leading to my TT, so I just converted to Atlas track after the bridge.  I do have some scaletrax (not visible) leading to the TT behind those Reading engines.  You just have to play with he height adjustment.  Here is my Atlas TT and Atlas track as whiskers.

Have Fun!  Ron

I don't use Realtrax but I would think there should be a transition piece so you can transition from Realtrax to Atlas or Gargraves on the approach to the turntable. Then all the tracks connected to the turntable would be Atlas or something readily compatible.

I run my Fastrack right up to my Atlas TT.  As Ron045 said for the Realtrax, you just cut back the plastic road bed a bit, and it will butt right up perfectly and fit in the space for the track on the turntable.

I do use Atlas track for the legs going into the Roundhouse.

Then as far as DCS operation, just as others have said, just run the TT track power wires into your power feeds and the DCS signal will be present on the Turntable bridge.

Thanks for the responses everyone. I do have one more question/concerns. With turntable operation, are there phasing issues between the turntable track and the whiskers? I could see that limiting travel to a specific orientation every time. 

Thanks,

No, there are no phasing issues.  That's another one of the benefits of 3-rail versus 2-rail.

Use a 40-1011 RealTrax and Atlas #6095 to transition from RealTrax to Atlas track. Do the RH/TT in Atlas.
