I have several curves similar to this in my switching yard.
All come off of radius curves that will not allow for
anything but slower speeds to enter.
The biggest problem I have encountered is the
binding I will sometimes get on some of my
rolling stock. this can be fixed with some modifications.
You are doing just fine. Heck, I have s curves,
u curves a few g curves and a T curve.
Just kidding. Lay it down and see what happens.
Best=it works fine.
Worst=pull up the pins and try something different!
