Reverse loop design ideas wanted

Turning my trains around after traveling down the 24ft long x 1ft wide shelf.
I will use a 23 5/8" radius. Should I use a s curve or a angled straight at 15degrees to 30 degrees to get back to the junction?
Please provide any ideas or plans.This will be agriculture area.The 15 degree angle provides a longer Tapered run vs a shorter
nub by using  a s curve.

Personally, I would avoid the S curve.

I would recommend getting at least 8" or so (more if you're running longer cars) of straight track in there. Make it long enough that each loco and car can negotiate one curve at a time. The longer the straight section, the better, but of course that will eat up linear space.

Got a plan that you can post?

Im with Eric. I set up a reverse loop in my hidden staging with a S curve in there and while cars with couplers on the trucks behind 1 loco worked fine, as soon as I added a loco it all went bad. I added a straight section double the length of the logest car / loco I ahve in order for them to navigate each turn individually and all my problems went away..
