Now that is an interesting twist as I'd never expected to hear about O gauge trains sharing track with PlaRail, although it does make sense when you describe it like that. I'm aware that you can get some O gauge battery powered models out there, would be interesting to see one of those chasing after Thomas LOL!!
I'm aware of the 3D system that you mention and have considered looking into it more closely. However lack of space for O gauge is what has put me off till now. These models that I've been buying are stunning, but due to my space constraints are unfortunately only likely to be destined to be display models unless things change somehow...

Happily collecting things all my life...
