Scott, sorry, but RR-Track won’t let me save in 4.0 format. The best I can do is post photos to show the changes. Unfortunately, company is coming, so I won’t get to it until tomorrow.
The problem with adding just 1 crossover where you drew the red circles is that once you turn the engine, you can’t turn it back. You’d have to add another crossover with 2 left-hand switches. I don’t know how many engines you have or intend to buy, but my solution would be to simply dedicate engines to run in opposite directions. I will see if a double crossover can be added there of if 1 can be added somewhere else. I’m a fan of being able to turn engines and trains, so it’s just a matter of what will fit.
BTW, I assume you know you’re going to have to cut tracks to make everything connect.
