Anyone Run HO Trains With Your 0 Train On One Of Your Layouts?

Houston Tinplate runs "N" on the large portable layout in Memorial City Mall.  Ii is their version of the "Hermann Park Railroad"

Sure!  I don't have the space for a large layout so my plans have centered around a compact stacked layout similar to the active display in my LHS.  It needs to fit in my crawl space area but be modular enough to get through the access way. 

Here's a photo of the second prototype.  I wanted bigger loops so I never finished it. I've since disassembled it and gave it to one of my employee's son so he can get a jump on the hobby. (I did keep the whiskey tumbler/beer holder assembly for myself.)

The third prototype is still on paper at this time.  Incorporating the lessons learned from the first two. I also wanted to work the Atlas O-90 and o-81 loops into the lowest level for larger steam.  I also wanted it to be simple to breakdown, transport, and re-assemble.  That way maybe I'll take it to the Dupage Train show at some point.

When operational I'll be able to run 6 HO-gauge and 4 O-gauge trains at the same time.  I'll live with the creative "compressed" perception of depth as one's view looks up the mountain.

No, to me HO has a historical rub. O-Gauge dominated the model train scene in the fifties and I was very happy about this. Then came along HO that changed the market greatly. I understand all the reasons why, but it has always been a nag to me, so no HO, NEVER.
