NEW LAYOUT

Robert, I want to make sure I understand. From what you just said and what I've gathered from past discussions. you have the following:
- 1 LT O72 switch
- 1 RT O72 switch
- 1 LT O48 switch
- 2 RT O36 switches
- various other straights and curves???

I believe you also said at some point that you don't want to buy any more switches. Is that all correct?

If so, here's what I see you working with as far as switches go.

Sorry, but given the limited number of switches and O72 ovals, I'm not coming up with much. There aren't enough switches to make a double crossover, so that means that once you go from one oval to the other you can't go back without backing up or at least reversing the engine. It's the same with only 1 reversing loop. If you're running diesels that's not so bad, but steamers will be more difficult.

Okay, Robert, here's a clean version of you buy the 2 O72s and 1 O48 switches. I noticed you didn't include the O36 switches.

As I'm sure you'll notice, I moved the crossovers to the corners on the curves. This will let you run faster speeds and transition through the crossovers without any hint of "S" curves between the switches. You still have the problem of only 1 reversing loop, but at least you'll be able to transition back and forth between mainlines.

That's a good way to use what you have and looks like it will work. I'd probably change the 1 3/8, O48 7.5, 1 3/8 and 10 segment following the O48 switch to a 1 3/8, O48 7.5, 1 3/8, 4.5 and 5 for a little better fitment. Of course, there might be enough give for either combination to work.
