I have the new 2-10-0. It's an excellent runner. The lack of a trailing truck and a wiper on the axle of the front truck means that under certain unusual conditions, it may lose ground power when running slowly. Cure is to run a #20 or #18 wire from the wiper on the tender front truck to the tender frame, like under a speaker screw.
The lighting is excellent, with dimming headlights, interior light that goes off when moving, flickering firebox.
