Selling my Santa Fe 30-1304-1 2-8-8-2 steam engine. Engine is in like new condition, used, comes with box and all paper work. Dual motored articulated locomotive with syncronized puffs and chuffs, really impressive at slow speeds. Engine crawls smoothly at 2-3 SMPH. Has blackened side rods and wheels (unlike stock photo here 30-1304-1) Includes two cab figures.

400.00 includes shipping to lower 48 states.

What is the minimum operating radius this will take?

If you click on the link provided, & then select the "instruction manual" download icon near the bottom, it states the engine will run on 031.

Yep, I have run it on 0-31 without issue on Realtrax, even the switches.
