That sounds perfect.  I was scouting online and ran into a couple of those.  I thank you for the advice.

Of course while I was scouting I found a bunch of very cool stuff.  Out of curiosity - how many drive wheels are too many for O27 curves?

I dug through the box and found my old 1989 Lionel catalog.  Once again I found myself drooling over the Pennsylvania Railroad S-2 #6200 I lusted over as a kid.  Far too large and expensive for what I'm looking for now.  Perhaps someday if I keep falling down this very enjoyable rabbit hole...
