John,
This seems to be a bug in SCARM (I need to contact Mixy about it), so I don't use the Export option. If you hit the "Fit To Screen" menu button, you'll notice that the "fill" is based on the baseboard and not all the elements in your project. I believe this is the reason some of the jpeg image seems to be cut off.
Here's what SCARM "fits"...........
Here's what's actually in the project..........Note the green rectangle.
Instead, I use the Windows "Snipping Tool" to snip as much or as little of the SCARM image as I want. To find the tool, simply hit the Windows key and start typing "snipping tool". When you see it, you can pin it to the Start bar. It's really a handy tool for capturing anything on the screen and lets you mark it up to point out items of interest, like what I circled in Red.
And since I'm posting, I fiddled a bit with Jan's rendition to fit the new space. Note I simply added some straight tracks and another crossover just to point out that you need both in order to travel between inner and outer runs.
