OK John.   You got us off of our ivory towers.   You had to go and get practical.  

Good analysis.  Much more helpful to the OP.

Thank you Bob.  I hesitated because I didn't want to unnerve anyone--not my intent.  Guys are always saying to me "O scale takes too much room!"  And I point out the reality as above.  Technically it is significantly larger than HO; even the undersized stuff.  But, 3-rail was made to turn VERY sharply in order that people would have room for the oval of track.  In my day, the sets I saw were O27--that under a super-sharp HO scale 15 radius curve!  O looks awkward on O27, but it works.
