running american flyer next to lionel

I have had a layout I on a 4x8 sheet of plywood with four ovals, with two outer ovals with S cauge track, the center loop was O-27, and an elevated figure 8 made out of O-27.

I had not taken any photos of the layout, as it was completed about a month before I got my orders to miserable Rotten Groton, CT. I had to dismantle the elevated section prior to the move. 

It worked out fine, except for the cats getting in the way and causing a 4 train pile up.

After my primary use Flyer engine blew it's reverse unit (234 C&O GP-7), I dismantled the "Flyer Sector", and made a separate 4x8 layout for the Flyer trains. 

There is a Hobby shop in Warwick, RI (Apponaug Color Shop) that has a rather nice layout in the store that has N, HO, O, and G on it. All it is is 4 concentric ovals, but still very nice with a number of action accessories that vistors can operate. 

I had intentions of making a 8'x10 layout in the back room that would have had S, O, and G on it, but the destruction of my only G scale engine, a Bachman Southern 4-6-0 (The shell is intact, but the drive components are ruined.)

I opted to just leave the 4x8 layout in the back room for S scale, and utilize the rest of the space as a workshop for my "Large Scale Tinplate Train" a ride on train that is 8 3/4" gauge.

The O gauge layout was rebuilt to have 3 loops, the outer one is O-42 and connects to the middle loop via 4 turnouts, and has a siding for the Lionel Crane I have. The center loop is just no frills to run the Marx fat-wheelers I have with no issues. 

To top it off, there is an elevated end-to-end for the Lionel Gang car that I got for $20 (the guy I bought it from said it was broken, all it needed was to be pulled apart and cleaned.)

I could never choose one scale over the other. Then again, I have 6 gauges to work with. (N, HO, S, O, G, and 8 3/4")

I will post photos if anyone wants. I think the Apponaug Color Shop has a photo of it's layout on it's website.
