Looking at the world upside down

I've been working on building a 4x8 layout that was designed on a computer. Laying things out on the first half of the layout has been only as hard as it had to be, but laying things out on the second half is quite a bit more confusing.

The problem is a view divider that goes down the back. The two halves of the layout are completely separate, in an attempt to make the layout feel bigger. However, the track plan ignores this distinction, so tracks that are on the right-hand side of the plan go on the left-hand side of the layout.

The easy solution, of course, is to turn the diagram upside down. However, when revising the plan on the computer it's impractical to work on the plan upside down. My method of dealing with it is to think about what track connects where, and to make the revisions accordingly. That is working out much better.
