Turntables can be a great centerpiece of your layout, I would hate to have you remove what can be a lot of fun.

 

I might suggest the problem to solve is upgrading to a more significant turntable like one from Millhouse studios or perhaps Ross.  These newer designs have a much more robust and reliable drive system.

 

Just my 2cents

 

Just some ideas... I don't use these tracks, but I find making them fit is a pure custom exercise. The Atlas site has the manual for an HO TT-DC power and a double switch with a reversing switch and move switch. maybe that diagram would help.

 

Why not move the other half of the double crossover to the opposite side?

 

I thought a wye off the inside line to access the yard/TT would look nice. But, I can't make it fit. It would look good in the middle of the area, give you a long yard and a way to reverse the direction of a train prototypically.

 

Outside train crosses over to inside, travels to wye, changes cars, leaves in either direction, crosses over to outside line. You get the idea.

 

Anyway, perhaps it will stir a new direction for your ideas.

I suggest too watch

Model Railroad Yard Design, Tips, and understanding the basics of real railroad yards. Track plans

Man dont give up the turntable,get a better one.

Well the TT came off the board on Sunday, dispite the awesome rendering, I gave it a solid 4 hrs of work trying to get it to work right. So I've totally reworked the yard and after watching the video that was suggested I am happy with the result. I will post a pic after I get the few switches I ordered today.

Too bad on the TT. It is a focal point of the layout and cool to operate. I hope you left room for it. You'll want one later.

 

yeah, your dilemma caused me to practice with the Ross\Gargraves combo and some object creation. The mainlines are as close to your dimensions that you posted as I could get. Cut a lot of flex to make it work.

 

I am looking forward to seeing your design. Did you put the other crossover back-in?
