Wow. Great looking locomotives. Beats the heck out of anything I owned when I had a big HO layout.
I am currently trying to install a small oval of HO track, inside one part of the figure 8 in my O gauge layout. I plan to run an HO Gandy Dancer Handcar on it. My little oval has 12R curves (24 inch diameter curves). I have ordered the Handcar, and hope that that tiny short wheelbase loco can make it around those tight curves.
