Straight answer is definitely. Heck you can put a O-gauge layout in those dimensions

However it entirely depends what you want out of your layout. The 0-gauge one would probably be an industrial type layout or small MPD, the OO-gauge similar but bigger or an end-to-end fiddle to terminus. N-gauge you could get a decent roundy in.

Truth be known - quite tight.. under 2ft. Kids have run trains at well over realistic speeds for decades on 6x4 baseboards.

Whether that LOOKS right, is a different question, but it will run just fine.

Looking at the track plan I can see a lot of potential problems and revisions needed. Can I suggest that you drop a post in the layout planning thread so you can take some advice.

As it stands the terminus is pretty much unworkable which will ultimately frustrate you if you don't revise it.

Out of interest what is the benefit of the 2mm motor over the almost identically sized Mashima 1015?
