ANYBODY KNOW WHAT THIS ENGINE IS?

I am sure I will be challenged by somebody MUCH more knowledgeable in old  O scale, but that looks like the 4-6-0 kit sold by that guy in Tennessee (I think somebody has bought the company from him).  I think that kit goes way back, to Varney, when Varney was in O scale.  Interesting that it has O scale flanges on the drivers and three rail collectors.  Would it stay on any commercial three rail track system, even with flat top rails?

I'll second the Varney guess.  Basically a generic design that allowed for different wheel configurations for a number of medium sized steamers.  Whoever the manufacturer, it resembles this Atlantic and contains many of the same individual castings.

I BELIEVE YOU BOTH TO BE CORRECT . I REMEMBER THE VARNEY HO KITS AND EVEN BUILT A COUPLE THAT I PURCHASED IN SAND SPRINGS OK . FROM A SMALL GARAGE HOBBY SHOP .

NOW I MUST DECIDE WHEATHER TO ATTEMPT TO RESTORE THIS OR JUST LEAVE IT AS A NICE DISPLAY ITEM , TIME WILL TELL.

THANKS FOR YOUR INPUT.

Varney. I have "the same engine" in the 4-4-0 version. Very 3-rail-able in my case - deep flanges. One day I'll...after the next dozen projects.

Absolutely - the 3/2 rail manufacturers use the same running rail profile (code/height may vary) regardless of the presence of a third one (this has been discussed many times). Based on its age and 3-rail track of the time, it may have run on plain Lionel tubular.

The center flanged driver would probably limit you to big curves - even 072 could be too small. Switches - that may be another matter with the big hi-rail flange ways.

Neat loco; worth resto-bashing. Varney O-parts are found on eBay, from time to time. A modern can motor could be installed, if need be.
