There are two reversing loops but only work for trains running in the clockwise direction. There is no reversing loop if running in the counter clockwise direction. Can you rework one of the return loops?
Your layout has room for two independent loop tracks, but you only have one complete loop. I have two loop tracks for when I just want to run my trains, especially in opposite directions so the pass each other. I recommend you relook the area I circled to see if you can have two independent loops.
