Dave;
Your yard tracks are considerably varied in length. That may not matter to you, but we often end up wanting more yard than we have (to store all those cool cars we just had to buy! 😄
You can get a little more yard capacity into the same space, by making the tracks closer to the same length. This involves changing the "yard ladder" (the string of "turnouts," aka track switches, at the right end of your track diagram. If you start on the left and look at the turnouts there, they combine to make a yard ladder that slopes downward from left to right...........At the other end of your yard, the yard ladder slopes upward. This automatically shortens each successive yard track, as you go downward on the diagram.
What I suggest is to move the green (main line?) track at the far right, further down, and build a new yard ladder at this right-hand end of the yard that slopes upward. This will change the overall shape of the yard from an inverted pyramid/trapezoid shape, into a diamond shape, which will have all the tracks closer to equal in length. This will mean that each yard track will be close to the length of your present top yard track. This scheme uses the same number of turnouts, though you may have to purchase right-hand ones instead of left-hand ones for that end of the yard .
A good thing you have already included in your yard design is "simple" ladders. That means that the ladder forms a simple straight track through all the turnouts in it. Many plans use turnouts arranged in such a way that a backing train has to snake back and forth through the ladder. This is harder to do, without derailments, than to back the same string of cars along a straight line until they make only one turn, into the selected track.
This problem doesn't come up as often in a double-ended yard like yours.* The trains move forward much of the time. However, if you want to sort cars into trains, you will have some backing movements, and of course, your stub-end tracks will need to be backed into.
* I don't know if you have priced turnouts yet, but your design uses a lot of them, and that means a lot of money.
