Sorry, Dave, I didn't notice it either when I added the 48" spur to the file. At Any rate, the small piece is a 4.25" straight. Unfortunately, there's no combination of RealTrax track that will directly replace the 10" straight. You really need a 5.75" track, but you can try using a 5.5" to see if there's enough wiggle room in the Gold tracks to let it all fit. The problem there is it shifts the entire section up 4.25" and you'll need to shorten the Red yard spurs. Doing that will leave just the Green 10" straight past the switch and that might not be enough room for an engine to escape. I've added a different yard configuration for you to consider, if needed.
