How is it possible to connect to loops together using only a single track between the loops so that a train will run continuously? What sort of turnouts would be needed?
Here is a link to a graphic that gives you a very, very rough idea of what I’m talking about. This isn’t to scale at all, it just gives a basic idea of the space.

My basement looks like this, and I’m trying to think of a creatinve way to use the recessed coner that you see in the lower right corner.
You have to put a different connection in there. The classic is a “waterwings” or “dogbone” shape. Imagine two tear drops with the points facing each other and and connecting track connects the two points. Compare that to your diagram.
When you do this you will end up with reversing sections if you have a single connecting track. That means a train traversing between the loops will have to have the polarity of the rails changed under it.
A simpler way is to make two connectiing tracks between the two loops. Connect the two end loops with tracks so that a train running clockwise on one loop will enter teh other loop going clockwise (or vice versa)

It isn’t clear how much space you have in that recessed corner, but make sure there is enough room open alongside the layout to get back there! Keep in mind that you’ll have to get back there from time to time.
One thing you might consider is (assuming you have enough space in the recess) an out-and-back plan, with a loop on the upper portion and a yard and turntable in the lower portion and the recess–you can make up trains, send them out around the loop to various sidings and stops, then return them to the division yard to be broken down.
I hadn’t thought about the polarity issue. I was just looking for a way to save some space by only having one track. Having two connecting tracks will be just fine.
My idea is to have this loop dedicated to a train that makes a constant loop, so the turntable idea won’t fit that. It is worth considering for the rest of the tracks though.
